Abstract:
The Toro Formation of the Papuan Basin is the older diachronous fades correlative of the upper part of the Gilbert River Formation of the Carpentaria and Laura Basins. In the Carpentaria Basin the upper Gilbert River Formation is composed of the Coffin Hill Member which occurs in the southern part of the basin, and the Gleanie and Briscoe Members which occur in the Olive River area within the northern part of the basin. The Toro Formation is of Early Berriasian to Early Kimmeridgian age, and the Gilbert River Formation is of Late Barremian to Late Tithonian age. Surface sedimentologic data and subsurface core and wireline log interpretations are supportive of a revised Toro Formation to incorporate all shallow marine reservoir quality sandstones. A subdivision of the Toro Formation into an upper and a lower member is proposed, based on the amount of sandstones. The upper member is composed dominantly of sandstones and minor siltstones and mudstones. The lower member is highly variable and consists of sandstones, siltstones and mudstones. Sandstones in both the Toro Formation and the Gilbert River Formation are composed predominantly of plutonic monocrystalline quartz (85-95%), and minor feldspars and muscovite mica (<15%). They are classified as quartz arenites and quartz wackes based on the predominant amount of quartz and minor feldspar, and variable matrix content. The detrital constituents of quartz, feldspar and mica indicate that the provenance was a mixed terrain of intrusive igneous and high grade gneissic metamorphic rocks. Fades analysis of the Toro Formation indicates a total of twelve subfades that were deposited in three major environments within a shallow marine wave dominated prograding barrier bar to beach environment: (1) Lower shoreface, (2) Middle shoreface, and (3) Upper shoreface-beach. From the lower shoreface toward the upper shoreface to beach fades, there is an increase in grain-size, decrease in the intensity of burrowing activity, and improvement in reservoir quality. Fades analysis of the Gilbert River Formation indicates a total of six subfades that were deposited in five subenvironments within a fluvio-deltaic to shallow marine environment: (1) Fluvial channel/point-bar, (2) Fluvial flood plain, (3) Distributary channel/mouth bar, (4) Pro-delta, and (5) Barrier bar to beach. The Gilbert River Formation fades generally becomes more marine in ascending stratigraphic order. Reservoir quality sandstones in the Toro Formation are present in the barrier bar to beach fades. Optimum areas where reservoir sandstones in the upper member may have accumulated are the northern and northeastern margins of the basin. Potential areas where the lower member reservoir sandstones may have accumulated are the northeastern and southeastern margins of the basin. Reservoir quality sandstones in the Gilbert River Formation are present in the fluvial channel/point-bar fades, delta front distributary mouth bar fades, and the prograding barrier bar to beach fades.

Abstract:
Detailed facies analysis and sequence stratigraphic principles applied to outcrop and subsurface data have aided in the development of a reservoir geological model for the Pacoota P3B Unit at the Mereenie Field, Central Australia. Mereenie is a linear Northwest/southeast trending oil and gas field 4 km wide and 35 km long, and covers an area of approximately 130 km2. In this field, oil and gas are produced from some of the oldest known petroleum reservoirs in the word: reservoirs approximately 500Ma. The Ordovician Pacoota P3B Unit, is part of an overall transgressive succession which records the transition from non-marine to marine environments in the northeastern margin of the Amadeus Basin. This transgression was punctuated by episodic events of rapid sea level rise and periods of sea level fall. The resulting vertical succession consists of three Fourth-order deltaic sequences formed by the regular alternation of sand-prone, non-marine sediments with marine mud/sand-prone deposits that prograded northeast as the basin subsided. Unlike previous investigations, this study recognizes four distinct types of sandstone facies associations within the broad braid delta system that characterizes the Pacoota P3B Unit. Facies Association 1 records the depositional characteristics of a distal braid plain that was dominated by episodic sheetflood events. Facies Association 2 reflects a sudden change in fluvial style from fine-grained sheetflood lobes to a coarse to pebbly-grained braid-delta system during a short-lived regressive phase. With time, this basal braid-delta system evolved into a tide-influenced braid plain indicating a transgressive phase. Facies Association 3 records the abrupt change from fluvial to tidal processes. This association is interpreted as the product of a tide-dominated delta front that prograded northeast. The palaeoenvironment of Facies Association 4 is interpreted as the fill of a wide incised fluvial valley system, which marked the end of fluvial sedimentation at the margin of the Amadeus Basin during the Ordovician. This association is capped by the transgressive marine deposits of the Pacoota P3A Unit. These four facies associations represent a complex network of depositional environments that results from the deposition of superimposed sandy, deltaic systems affected by tidal currents. The vertical facies evolution is punctuated by erosional sequence boundaries. The development of a detailed stratigraphic framework allows the Pacoota P3B Unit to be subdivided into five correlative intervals that define reservoir compartments in the Mereenie Field. These reservoir compartments are bounded by key stratigraphic surfaces and represent the lowstand (LST), transgressive (I'ST) and highstand (HST) systems tracts of the Fourth-order sequences defined within the P3B Unit. Maximum reservoir quality is associated with amalgamated fluvial sandstones that define the LST of each sequence. Marginal to impermeable reservoir characteristics occur within the tidally-influenced TST and HST. From base to top reservoir intervals are: P3-250, P3-230, P3-190, P3-150 and P3-120/130. Of these, the lowstand P3-120/130, P3-230 and P3-250 Reservoir Intervals are the most prolific producers. The transgressive to highstand P3-150 and P3-190 Reservoir Intervals are considered as not economically profitable for hydrocarbon exploitation. Petrophysical characterization of lithofacies types observed in the succession indicate that within each compartment, depositional facies exert the primary control on reservoir properties. Flow units are associated with tabular, cross-bedded sandstones. Permeability barriers are associated with bidirectional cross-beds, parallellaminated sandstones, soft-sediment deformed sandstones and bioturbated beds. During transgression the upper part of the lowstand fluvial system was sheared off resulting in a transgressive surface capping the fluvial deposits. Reworked fluvial sediments were redeposited as reversing tidal flows above the lowstand intervals. These deposits, interpreted as neap-spring tidal cycles, consist of alternating sand and silt/mud and bioturbated beds. In this setting, intense bioturbation generate sediment mixing destroying the reservoir properties of this interval. Additionally the areally continuous and impermeable silt/shale intervals of the tidal deposits contributed to the vertical barriers to flow in the reservoir. This study illustrates how facies analysis and high resolution sequence stratigraphy can be applied to improve reservoir characterization in fluvio-marine successions deposited before the existence of land vegetation. In the Mereenie Field, these concepts have been successfully applied to: i) recognize with confidence all correlative reservoir intervals and ·ii) identify, orientate and map the LST of the Fourth-order sequences which represent the major reservoir intervals of the P3B Unit.

Abstract:
[Truncated abstract] The realization in 1999 that the authigenic phosphate, xenotime, could be used in geochronological studies to place age constraints on burial events that affected sedimentary basins has opened numerous opportunities for establishing timeframes for sedimentary basin analysis. Since then, the mineral has been used to place new and novel age constraints on diagenesis, metamorphism, and hydrothermal alteration and mineralization events. Whilst these studies were successful, they identified many complexities in xenotime growth and were restricted to specific areas or single basins: they do not convey, demonstrate or explore the immense variety of geological applications in which xenotime may provide unique geochronological constraints. This thesis explores the nature of authigenic xenotime, utilizing studies in three different Proterozoic sedimentary basins: two in Australia, southwestern Australia and the Northern Territory, and the third in the United States of America. The thesis includes a number of discrete studies demonstrating different aspects of xenotime growth, elucidated from detailed petrography, geochronology and geochemistry of authigenic xenotime. An integrated textural, geochemical and geochronological study of authigenic xenotime from the Mt Barren Group, SW Australia, establishes an absolute timescale on some of the many processes involved during the diagenesis of siliciclastic units. ... positions and trends and broadly confirm the chemical discrimination criteria established for an Archaean basin. However, the Proterozoic data are shifted to lower Gd-Dy values and extend beyond the original field outlines, causing more overlap between fields intended to discriminate xenotimes of different origin. The plots were revised to encompass the new data. This study has significantly extended our knowledge of the nature of authigenic xenotime. It was found that xenotime may form in (meta)sediments in response to a large number of post-depositional processes, including early- and latediagenesis, (multiple) basinal hydrothermal events and low-grade metamorphism. A combination of detailed petrography and in situ geochronology provides the best avenue to decipher complex growth histories in xenotime. With further development, it is likely that xenotime geochemistry will also prove diagnostic of origin and can be incorporated into the interpretation of age data. The number of potential applications for xenotime geochronology has been expanded by this study.

Abstract:
[Truncated abstract] The Collie River drainage basin is an important water resource catchment in southwestern Australia. Salinisation of a major water supply within the catchment, the Wellington Reservoir, has arisen due to changes in the water and salt balance in response to land clearing over saprolite aquifers. Paired catchment studies, the Collie Experimental Catchments (CECs), established in the early 1970’s in high and low rainfall areas increased our understanding of water and salt (predominantly chloride) movement in these aquifers through the collection and analysis of high resolution spatio-temporal data. However, the conceptual models developed from this work take little account of landscape heterogeneity, and this has caused problems in subsequent modelling studies, where success in calibrating stream flow has been countered by difficulties in predicting salt loads. The challenge remains to better describe variability in the Collie landscape and understand the influence of climate, vegetation, geology and geomorphology on observed water and salt fluxes. The release of salt from the lower saprolite aquifer and the role of the surficial aquifer in buffering groundwater discharge were investigated. The acquisition, analysis and interpretation of new regolith and geophysical data in 2001-2003 from the CECs, together with data from a high resolution digital elevation model, and existing drilling information, were used to construct a geologicalgeomorphological compartment framework, to observe changes in aquifer behaviour ... Significant differences in the salt flux from compartments have been noted at a range of scales, with implications for both water resource and land management. The approach developed to identify compartments and assess their efficiency could be simplified, using catchment critical parameters determined from geological and geomorphological characteristics. As a consequence, the implementation of a compartment framework in catchments with saprolite aquifers should allow for more informed decisions to be made in the selection of sites for revegetation strategies or the development of engineering works. This is particularly important in the Collie Catchment where reclamation scenarios are currently being discussed. Consideration of the catchment as a compartmentalised system would help manage salt loads in the Collie River and return the Wellington Reservoir to a functional water resource.

Abstract:
The Canning Basin is a large intra-cratonic basin which underlies an onshore area of 430,000sq. km. The study area, located on the Barbwire Terrace, contains a series of stratigraphic boreholes drilled by Western Mining Corporation Ltd., which provide fully cored sections through the previously poorly exposed Grant Group. From this core, integrated with seismic data and wireline logs, the Grant Group has been divided into three new formations, each containing a number of distinctive and intimately related facies types. The basal Hoya Formation comprises a complex suite of interbedded diamictites, sandstones and mudstones. The diamictites are interpreted as lodgement tills, melt-out tills and flow tills, deposited from the retreating ice sheet. Interbedded with the diamictites are massive and laminated mudstones, deposited under fluctuating marine and lacustrine conditions. Stacked cross-bedded sandstone units are restricted to the west of the study area, forming subsurface linear mounded features, clearly displayed on the regional seismic. These sandstones are interpreted to be deposited from braided fluvial outwash systems. However, the majority of sandstones are massive and normally graded, of mass-flow origin, deposited from a series of subaqueous fans fed by meltwater from the ice sheet. The overlying Calytrix Formation contains a thin basal sandstone unit, rich in marine fauna, but is characterised by a thick sequence of basinal mudstones. It is overlain by the Clianthus Formation, which has a basal fluvial sandstone unit, capped by heterolithic sandstones, siltstones and mudstones, interpreted to be shallow marine shelf deposits. The Grant Group sediments record the gradual deglaciation of the basin, and indicate that the ice sheet was extensive during the Perm- Carboniferous. The Hoya Formation contains all the glaciogenic sediments, and provides evidence for periodic ice advance and retreat. The mudrock dominated Calytrix Formation is interpreted to reflect the rise in sea level subsequent to the main deglaciation phase, and the regressive package of sediments that form the Clianthus Formation result from isostatic uplift and basin fill under post glacial conditions.

Abstract:
The Early Jurassic coal samples for the study were obtained from CRA Exploration Pty Ltd. (CRAE), drilled in the Gairdner and Mintaja Blocks, Gairdner Range of the Hill River Area, northern Perth Basin, Western Australia. The area is located approximately 280 km north of Perth. The coal measures subcrop in a half- graben bounded by the Lesueur-Peron Fault in the west, and the Warradarge Fault in the east. The coal occurs within the shallow sequence of the Cattamarra Member which is also described as the Cattamarra Coal Measures of the Cockleshell Gully Formation. Six sub-seams of seam G, namely G1 to G6, from the six drill cores, were examined for petrological and geochemical investigation. The coal predominantly comprises of banded, dull banded, and dull lithotypes, with minor bright banded, bright and fusainous types. Based on maceral analyses, the dominant maceral groups are vitrinite and inertinite, whilst the exinite and mineral matter are in minor contents. The vitrinite content has a range between 47.2% to 73.0%, and it is composed mainly of telocollinite and desmocollinite. The inertinite is dominated by semifusinite, fusinite, and inertodetrinite, and it has a range from 10.4% to 24.8%. The exinite group varies between 7.2% to 20.8% in content, and it is represented by sporinite, cutinite, alginite and resinite.The mineral matter dominated by clays and pyrite, ranges between 4.5% to 20.6%. The microlithotype analyses shows that the vitrite plus clarite content varies from 47.0% to 70.0%, intermediates between 8.0% to 26.0%, whilst inertite plus durite content is relatively low, varying from 6.55% to 14.0%. The maximum reflectance of vitrinite has a value between 0.47% and 0.53%, which represents rank at sub-bituminous level based on the Australian rank values and corresponding to the sub-bituminous A and B rank of the ASTM classification and to the metalignitous type of the Pareek classification. On the basis of carbon and hydrogen content, the coal is categorised as per-hydrous meta- to ortho-lignitous type. The trace elements As, B, Be, Cd, Co, Cr, Cu, Ga, Mn, Mo, Ni, Pb, Sr, Th, U, V, Y, Zn, and Zr, are spectrographically analysed in the coal ash. The B content in the coal supports the presence of marine influence during peat deposition in the basin. On the basis of lithotype, maceral, microlithotype, trace element distribution, pyrite and total sulphur in the coal, the depositional environment for coal and the coal measures, is interpreted as an upper to lower delta type within a regressive phase of marine transgression.

Thesis, University of Aberdeen, 1996. http://digitool.abdn.ac.uk:80/webclient/DeliveryManager?pid=229812.

Full text
Abstract:
Al Khlata Formation is an oil-bearing reservoir in Oman. Its origin during the Late Palaeozoic Gondwanan glaciation in the southern part of the Arabian Peninsula is demonstrated by its glaciogenic deposits. Outcrops of the AI Khlata Formation occur in a belt parallel to the Huqf fold axis, the best outcrops being found in the two wadis Al Khlata North and South. In the southern wadi, glacial deposits rest directly on dolomites of the Pre-Cambrian Khufai Formation, which have NE-SW trending glacial striations. One of the key aspects of this study was a detailed investigation of the outcrops which allowed the identification of the different facies units. Measured wadi-wall sections and lateral facies mapping allowed a better understanding of the complex nature of the depositional processes. This has further been integrated with the result of shallow boreholes cores to refine the correlation between the outcrops of Wadis AI Khlata North and South, and also the AI Khlata sequence in five oil wells between the Rahab and AI Huwaisah fields. Furthermore, a brief visit was made to Iceland to see a small active ice sheet and its marginal glacio-fluvial sediments, and also to W. Australia to see cores of the Permo-Carboniferous Hoya Formation from the Canning Basin for comparison with the Al Khlata Formation sequences. The AI Khlata Formation comprises four fades associations, which are further subdivided into facies. These are: (1) Diamictite Facies Association, which has been divided into a Massive Diarnictite Facies and a Stratified Diarnictite Facies, (2) Conglomerate Facies Association including Cross-stratified Sandy Conglomerate, Gravel Lag and Massive Gravel, (3) Sandstone Facies Association divided into Crossbedded Sandstone and Pebbly Sandstone and Rippled Sandstone, and (4) Fine-grained Facies Association which, in turn, has been divided into a Deformed SiltiMudstone, Laminated SiltstonelMudstone, Black ShalelMudstone, and Graded Rhythmite. These facies have been recognised in both outcrop and cores. Earlier workers proposed that the direction of ice flow was from the SW to NE. This is not accepted in this paper, where evidence is presented to support an ice-flow direction from NE to SW. Later fluvial flow towards the NE possibly resulted from the collapse of the continental margin towards a new Proto-Arabian Sea. The thesis presents a new hypothesis for the origin of the AI Khlata Formation. It is proposed that the Early Permian glaciation in Oman resulted from crustal uplift just prior to the calving of a microcontinent along the NE Arabia margin of Gondwana and the creation of Neo-Tethys. It is suggested that the triple-junction area, where Neo-Tethys and the Proto-Arabian Sea were later to meet, was a site of sufficient thermal uplift to become a centre of mountain glaciation.

Abstract:
Throughout the James Ranges and Gardiner Range the Arumbera Sandstone forms prominent strike ridges with distinctive dark reddish slopes and pale red to orange-white cliffs. Because of their lithologic and stratigraphic similarities, the names Eninta and ''Quandong" for these units should be suppressed in favor of the name of Arumbera Sandstone, which has precedence. The stratigraphic and lithologic differences observed between the Quandong Conglomerate in the type locality and the Arumbera Sandstone in the study area suggest that these units are not equivalent. Similarites with the Areyonga Formation suggest the Quandong Conglomerate could be part of the Areyonga Formation. Lithofacies la, ld, and 2b, and Unit 3 of the Arumbera and its equivalents are typically recessive arkoses, subarkose, and mudrocks. They are interpreted as nearshore-marine to coastal deltaic deposits which include intertonguing tidal-flat, tidal-channel, and beach sediments. Lithofacies 1b and 2a consist of cliff-forming arkoses, subarkoses, and lithic arkoses. Lithofacies 2c is also resistant, and consists of orthoconglomerates and conglomeratic sandstones. Lithofacies 1e is moderately resistant, and consists of paraconglomerates, conglomeratic sandstones, and mudrocks. It and lithofacies 2c contain pebbles and small cobbles of chert, quartzite, vein quartz, silicified ooids, and limestone, dolostone, shale, and sandstone. These four lithofacies are interpreted as braidplain and fluvial sheet sands. In the east-central part of the Amadeus Basin the Arumbera Sandstone probably was deposited in a coastal environment as a sequence of deltaic sediments that was dominated by fluvial processes. The Arumbera Sandstone appears to be the molasse derived from the Late Proterozoic and Early Cambrian Petermann Ranges orogeny. Source rocks include sedimentary, low- to middle-rank metamorphic, and plutonic granites. Grain mineralogy and weathering characteristics suggest a hot, semiarid climate during deposition of the Arumbera. The Arumbera Sandstone and Quandong Conglomerate contain fair to good porosity and permeability, and petrographic evidence shows mesogenetic generation of secondary porosity. Previous and present burial depths are adequate for the generation of petroleum. The presence of suitable underlying .source rocks, overlying salt of the Chandler for a seal, and stratigraphic and structural traps suggest a good potential for petroleum. Production of dry gas from the lower part of the Arumbera at Dingo field, north of Deep Well Homestead, confirms the petroleum potential of this formation.

Abstract:
The Giles Creek and upper Chandler formations crop out in the northeastern Amadeus Basin from the north flank of Ross River syncline south to the Pillar Range, and from the nose of Ooraminna anticline east to the Simpson Desert. 'Twenty-four sections of the Giles Creek and nineteen sections of the upper Chandler were measured by the author in this area. The Giles Creek lies disconformably above the upper Chandler Formation and conformably below the Shannon Formation. The upper Chandler is conformably underlain by the lower Chandler throughout the area except at Ross River Gorge and Wallaby No. 1 well. There the upper Chandler overlies the Todd River Dolomite. The Giles Creek and upper Chandler consist of interbedded carbonates, terrigenous-rich carbonates, and mudrocks. Terrigenous-rich carbonates and mudrocks comprise over half of the volume of the Giles Creek at most locations in the area. Lime mudstones and cryptalgalaminated boundstones with dorral stromatolites are common in the Giles Creek. The Phillipson and Northern Facies of the Giles Creek are locally fossiliferous at the base. Ooids are present at the top of the Southern and Phillipson Facies of the Giles Creek at most locations. Anhydrite is present in the carbonates and mudrocks of the Giles Creek at Dingo No. 1 and Wallaby No. 1 wells. Gypsum is present in dolostones of the Giles Creek at Wallaby No. 1 well. Oncolite grainstones and boundstones, crystalgalaminated boundstones, and birdseye-rich lime mudstones are common in the upper Chandler. The mudrocks of the Giles Creek and upper Chandler are composed of quartz, K-feldspar, illite, muscovite, biotite, kaolinite, smectite, plagioclase, and anhydrite, with minor amounts of limonite, hematite, vermiculite, chlorite, and zircon. Calcite and dolamite cement the mudrocks. Acid-insoluble residues of the carbonates are comprised of the above noncarbonate minerals, organic matter, pyrophyllite, and witherite. The size and amount of terrigenous material in the Giles Creek increases to the west-southwest, which indicates that the terrigenous sediments were derived from a source area in that direction. Sediments of the Giles Creek and upper Chandler were dolomitized by seepage-reflux of a hypersaline brine. Lateral and vertical variations in the amount of dolanite are inversely related to the amount of terrigenous material, and indicate that permeability of the sediments was a controlling factor in the distribution of dolomite in the Giles Creek. Sediments of the Giles Creek and upper Chandler accumulated on shoals, in shoal-margin lagoons, on tidal flats, and in intracoastal lagoons. Shallow, open-shelf deposits are also present at the base of the Giles Creek at Ross River Gorge. Cyclicity in the sediments of the Giles Creek was caused by lateral shifts in the position of the tidal flats and intracoastal lagoons during continual subsidence of the basin. Both the Giles Creek and upper Chandler -were deposited during major regressions of the sea. Lateral relations of lithofacies in the Giles Creek indicate that the area was bounded by deeper water to the north and south during the Middle Cambrian. Differential subsidence of the basin resulted in deposition of greater thicknesses of Giles Creek sediments in the Phillipson Pound and Ross River-Fergusson syncline areas. Differential subsidence in the Phillipson Pound area was partially offset by salt-induced growth of Ooraminna, Tood River-Windmill, Brumby, and Teresa anticlines. Facies relations and lateral variations in thickness of the Giles Creek suggest that the amount of offset on the Rodinga and Carrel Flat faults is minor, perhaps on the order of 1 to 2 kilometers at most. Initial carbonate sediments of the Giles Creek and upper Chandler were altered by syngenetic inversion of aragonite to calcite, recrystallization of calcite, precipitation of pyrite, and replacer-rent of calcite by dolomite; anagenetic silicification, compaction, and fracturing; and epigenetic oxidation, precipitation of calcite, dedolomitization, and silicification. Post-depositional changes in the terrigenous sediments include syngenetic oxidation, alteration of clay minerals, precipitation of silica, and dolomitization.

Abstract:
Il Bacino del Browse è localizzato nella porzione offshore del margine Nord-occidentale Australiano. La formazione di questo bacino è legato al susseguirsi di sei fasi tettoniche, a partire dalla fase di rift Permiana fino alla fase di breakup unconformity, che ha portato alla definizione strutturale del margine NW Australiano. In questo lavoro di tesi si è studiata l’evoluzione del margine successiva alla breakup continentale, i corpi sedimentari depositatisi a partire dalla base del Cretacico fino al Neogene e la fase di inversione oligo-miocenica. In particolare è stata studiata una struttura anticlinalica localizzata nella porzione meridionale del Bacino del Browse (Barcoo Sub-Basin). L’inversione strutturale è avvenuta a partire dall’Oligocene Medio. Nel Bacino del Browse si sono formate diverse strutture di inversione in prossimità della piattaforma. Lo studio di dettaglio si è basato sulla interpretazione di 8 profili sismici acquisiti da AGSO (Australian Geological Survey Organisation), tarati tramite dati di pozzo. Lo studio ha mostrato che il bacino è stato soggetto a variazioni nell’accomodation in risposta a variazioni nel tasso di subsidenza, apporto sedimentario e variazioni relative del livello del mare dal Cretacico fino al Miocene superiore. È stato inoltre osservato come la variazione nell’accommodation sia stato il principale fattore, rispetto alla strutturazione tettonica, che ha influenzato l’architettura dei corpi sedimentari. La geometria dei depositi, in particolare quelli oligo-miocenici, sembra essere poco influenzata dalla crescita delle strutture di inversione. L’architettura deposizionale risulta la medesima sia nelle zone di culminazione assiale dell’anticlinale sia nelle zone in si registra la chiusura della struttura stessa.

Full text
Abstract:
The Arumbera Sandstone consists of mappable informal units which are repeated in a vertical, cyclic succession. Sandstones of fluvial origin form resistant strike ridges separated by strike valleys, which consist of recessive sandstones and mudrocks of marine origin. Lithofacies 1a, 2b, and 3a are probably of marine origin in intertidal environments. Trace fossil assemblages in lithofacies 3a suggest Skolithos and Cruziana inchnofacies were present. Lithofacies 1e, 2a, 2c, 3b, and 4a are probably of fluvial origin, as the result of coalescing braided stream deposits. The Arumbera Sandstone probably was deposited in a deltaic environment characterized by low wave energy, a micro tidal range, and high input of sand-sized sediment br braided streams. In the western MacDonnell Ranges, the Arumbera overlies the Julie or Pertatataka formations along a sharp but conformable contact. The present upper contact is a low-angle regional unconformity which contains paleotopographic elements that resemble pediments, stripped structural plains, and steep erosional scarps. These paleotopographic surfaces are overlain from east to west by the Chandler, hugh River, and Cleland formations in an onlap relationship. The Arumbera Sandstone is considered part of a molasse sequence associated with the Late Proterozoic and Early Cambrian Petermann Ranges orogeny, which occurred along the present southern and southwestern margin of the Amadeus Basin. The uplifted Petermann Ranges shed detritus from metamorphic, sedimentary, and minor amounts of plutonic rocks. Paleocurrents suggest most terrigenous material was derived from the southwestern margin of the basin. The composition of detrital grains and lack of weathering features in labile detrital grains suggest a hot, semiarid to arid climate in the source area and in the basin of deposition. Sandstone samples examined petrographically primarily are subphyllarenites, subarkoses, arkoses, feldspathic litharenites, and lithic arkoses. The inferred paragenetic sequence is: Eogenetic: (1) mechanical compaction, (2) "dust rims" of hematite, illite, and chlorite, and (3) hematite cement; Mesogenetic: (4) syntaxial feldspar overgrowths, (5) syntaxial quartz overgrowths, (6) hematite cement, (7) carbonate cement, (8) kaolinite replacement, (9) formation of secondary porosity; Telogenetic: (10) chert cement and (11) gibbsite or hematite cement.

Full text
Abstract:
Alkalic porphyry style Au-Cu deposits of the Cadia district are associated with Late-Ordovician monzonite intrusions, which were emplaced during the final phase of Macquarie Arc magmatism at the end of the Benambran Orogeny. N-striking faults, including the curviplanar, northerly striking, moderately west-dipping basement thrust faults of the Cadiangullong system, developed early in the district history. NE-striking faults formed during rifting in the late Silurian. Subsequent E-W directed Siluro- Devonian extension followed by regional E-W shortening during the Devonian Tabberabberan Orogeny dismembered these intrusions, thereby superposing different levels porphyry Au-Cu systems as well as the host stratigraphy. During the late Silurian, the partially exhumed porphyry systems were buried beneath the Waugoola Group sedimentary cover sequence, which is generally preserved in the footwall of the Cadiangullong thrust fault system. The Waugoola Group is a typical rift-sag sequence, deposited initially in local fault-bounded basins which then transitioned to a gradually shallowing marine environment as local topography was overwhelmed. Basin geometry was controlled by pre-existing basement structures, which were subsequently inverted during the Devonian Tabberabberan Orogeny, offsetting the unconformity by up to 300m vertically. In the Waugoola Group cover, this shortening was accommodated via a complex network of minor detachments that strike parallel to major underlying basement faults. For this reason, faults and folds measured at the surface in the sedimentary cover can be used as a predictive tool to infer basement structures at depth.

Abstract:
This thesis consists of six published papers. The present-day stress tensor has been determined using petroleum well data in the Gippsland and Otway Basins in Southeast Australia (Papers 1 and 4) and the Cooper Basin in Central Australia (Paper 5). In the Gippsland Basin, the present-day stress regime is transitional between one of reverse and strike-slip faulting and the maximum horizontal stress (SHmax) is oriented ~139°N. The present-day stress regime in the Victorian sector of the Otway Basin is also transitional between one of reverse and strike-slip faulting and SHmax is oriented ~135°N. Horizontal stresses are lower in the South Australian sector of the Otway Basin where the stress regime is one of strike-slip faulting and SHmax is oriented ~124°N. The orientations of SHmax in Southeast Australia are consistent with focal mechanism solutions, neotectonic structures and modelling of plate-boundary forces (Paper 4). Closure pressures from mini-frac injection tests are commonly used to determine the minimum horizontal stress (Shmin) magnitude. However, in high stress basins such as the Cooper and Gippsland Basins, these pressures may not reliably yield Shmin (Papers 2 and 5). In the Cooper Basin, high closure pressures (>18 MPa/km) were observed in tests where pressure-declines indicated complex hydraulic fracture growth. Closure pressures in these injections are unlikely to be representative of Shmin. They are believed to reflect the normal stress incident on pre-existing planes of weakness that are exploited by hydraulic fluid during the mini-frac injection (Paper 5). Sub-horizontal fabrics that are open at the wellbore wall were observed on image logs in the Cooper and Gippsland Basins (Papers 2 and 5). This fabric is believed to be at least partially responsible for the complex growth of hydraulic fractures observed in the Cooper Basin. The occurrence of these sub-horizontal fabrics and knowledge of rock strength have been used to constrain the magnitudes of SHmax and Shmin independently of mini-frac injections in the Cooper and Gippsland Basins (Papers 2 and 5). The present-day stress tensor is often quoted as a single gradient at a sedimentary basinor petroleum field-scale. Image logs and mini-frac data from Central and Southeast Australia indicate significant stress differences between stratigraphic units (Papers 3 and 5). Finite element modelling of the stress distribution between interbedded sands and shales in the Gippsland Basin indicates that stress is ‘partitioned’ to ‘hard’ lithological units in high stress areas. This accounts for the observation that borehole breakout only occurs in hard, cemented sandstones in the Gippsland Basin (Paper 3). A generic ‘mechanical stratigraphy’ derived from knowledge of wellbore failure (from image logs), rock strength and rock properties in individual rock units in the Cooper Basin allows an approximation of the present-day stress-state to be made directly from image-logs for individual rock units prior to mini-frac injection (Paper 6). This is important for predicting and understanding hydraulic fracture growth and containment. When considered together, the papers comprising this thesis provide significant new data on the orientation and magnitude of present-day stresses in Central and Southeast Australia. They also provide insight into the tectonic origin of those stresses and their distribution within sedimentary basins. In particular the papers develop and use new methods for constraining the present-day stress in regions of high tectonic stress. They also discuss implications for problems in petroleum development including wellbore stability and hydraulic fracturing.

Full text
Abstract:
2D and 3D basin models have been constructed of the southern and central parts of the Vulcan Sub-Basin, which is located in the Timor Sea, north-western Australia. This work was carried out in order to better elucidate the petroleum migration and accumulation histories and exploration potential of the region. The study area extended from the southern limit of the Swan Graben in the south-west to the northern part of the Cartier Trough in the north-east. The results from the basin modelling have been compared with the seafloor bathymetry and physiography, the spatial distributions of hydrocarbon related diagenetic zones (HRDZs) in the region, as well as the distribution of other leakage and seepage indicators. A new method for identifying potential HRDZs using seismic data has also been developed. The 2D/3D modeling results from the Swan Graben indicate that horizontal and downward oil expulsion from the source rocks of the Late Jurassic Lower Vulcan Formation into the upper Plover Formation sandstones was active from the Early Cretaceous to the present day. Oil migration from the Lower Vulcan Formation into the Late Cretaceous Puffin Formation sands in the Puffin Field was simulated via lateral migration along the bottom of an Upper Vulcan Formation seal and by vertical migration above the seal edge. Modelling also indicates that Late Jurassic sequences over the Montara Terrace are thermally immature and did not contribute to the hydrocarbon accumulations in the region. On the other hand, 3D modelling results indicate that the Middle Jurassic Plover Formation in the Montara Terrace became thermally mature after the Pliocene and hence it could have contributed to both the specific hydrocarbon accumulations and the overall hydrocarbon inventory in the area. In the southern Cartier Trough, the Lower Vulcan Formation is typically at a lower thermal maturity than that seen in the Swan Graben, due to a combination of a relatively recent (Pliocene) increased burial and a thinner Lower Vulcan Formation. Here, horizontal and downward oil/gas expulsion from the Lower Vulcan Formation into the Plover Formation sandstone was active from the Late Tertiary to the present day, which is significantly later than the timing of the expulsion in the Swan Graben. In the central Cartier Trough, the areal extent of both generation and expulsion increased as a result of rapid subsidence and deposition from about 5.7 Ma to the present day. This Pliocene loading has resulted in the rapid maturation of the Early to Middle and Late Jurassic source system and expulsion of oil very recently. Oil migration from the Lower Vulcan Formation into the Jabiru structure, via the Plover Formation carrier bed, was simulated in both the 2D and the 3D modelling. In particular, the 3D modelling simulated oil migration into the Jabiru structure, both from the southern Cartier Trough (after the Miocene) and also from the northern Swan Graben (in the Early Cretaceous). Early gas migration, and the attendant formation of a gas cap, was also simulated. Importantly, this result provides a potential alternative interpretation for the formation of at least some of the residual zones in the Timor Sea, as well as in other areas. Traditionally, most of the residual zones within the Timor Sea have been attributed to fault seal reactivation and failure. However, the simulated early gas cap in the Jabiru structure has formed as a result of gas exsolution as the migrating hydrocarbons entered the Jabiru trap (and its shallow flanks), which was then only located a few hundred metres below the surface. The rapidly decreasing pressure allowed the gas to form a separate phase, with the result that in the Early Cretaceous, in the 3D model, the Jabiru trap was composed of a relatively large gas cap with a thinner (“black oil”) oil leg. Progressive burial through the Tertiary, and the attendant increase in pressure, resulted in the gas going back into solution. The associated decrease in the bulk volume of the hydrocarbon accumulation produced a “residual” oil zone at the base of the column, purely through a change in phase, rather than through loss of hydrocarbons from fault seal failure, for example. The processes outlined in this scenario would be essentially indistinguishable from those produced by fault seal failure when assessing traps using fluid history tools such as GOI. Such a process could be critically important in the case of shallow, low-relief traps, where only the exsolved gas could be trapped, with the “black oil” component displaced below the spill of the trap. Small, sub-commercial gas fields would thus be located around the periphery of the source depocentres - though these would be the result of an early, rather than late, gas charge. Small black oil accumulations could be developed inboard from such gas fields. A new method to extract HRDZs from 3D seismic data has predicted the location of new HRDZs in the northern Vulcan Sub-basin. Further investigation is needed to confirm/refine the method but it has the potential to significantly aid HRDZ mapping (and seal assessment and hydrocarbon migration studies). A workflow for future studies is proposed which includes inputs from basin modelling, leakage and seepage mapping, and fault seal and fault reactivation studies. Implementation of this workflow should ultimately allow a more reliable estimation of GOR prior to drilling.

The study area extended from the southern limit of the Swan Graben in the south-west to the northern part of the Cartier Trough in the north-east. The results from the basin modelling have been compared with the seafloor bathymetry and physiography, the spatial distributions of hydrocarbon related diagenetic zones (HRDZs) in the region, as well as the distribution of other leakage and seepage indicators. A new method for identifying potential HRDZs using seismic data has also been developed. The 2D/3D modeling results from the Swan Graben indicate that horizontal and downward oil expulsion from the source rocks of the Late Jurassic Lower Vulcan Formation into the upper Plover Formation sandstones was active from the Early Cretaceous to the present day. Oil migration from the Lower Vulcan Formation into the Late Cretaceous Puffin Formation sands in the Puffin Field was simulated via lateral migration along the bottom of an Upper Vulcan Formation seal and by vertical migration above the seal edge. Modelling also indicates that Late Jurassic sequences over the Montara Terrace are thermally immature and did not contribute to the hydrocarbon accumulations in the region. On the other hand, 3D modelling results indicate that the Middle Jurassic Plover Formation in the Montara Terrace became thermally mature after the Pliocene and hence it could have contributed to both the specific hydrocarbon accumulations and the overall hydrocarbon inventory in the area. In the southern Cartier Trough, the Lower Vulcan Formation is typically at a lower thermal maturity than that seen in the Swan Graben, due to a combination of a relatively recent (Pliocene) increased burial and a thinner Lower Vulcan Formation. Here, horizontal and downward oil/gas expulsion from the Lower Vulcan Formation into the Plover Formation sandstone was active from the Late Tertiary to the present day, which is significantly later than the timing of the expulsion in the Swan Graben. In the central Cartier Trough, the areal extent of both generation and expulsion increased as a result of rapid subsidence and deposition from about 5.7 Ma to the present day. This Pliocene loading has resulted in the rapid maturation of the Early to Middle and Late Jurassic source system and expulsion of oil very recently. Oil migration from the Lower Vulcan Formation into the Jabiru structure, via the Plover Formation carrier bed, was simulated in both the 2D and the 3D modelling. In particular, the 3D modelling simulated oil migration into the Jabiru structure, both from the southern Cartier Trough (after the Miocene) and also from the northern Swan Graben (in the Early Cretaceous). Early gas migration, and the attendant formation of a gas cap, was also simulated. Importantly, this result provides a potential alternative interpretation for the formation of at least some of the residual zones in the Timor Sea, as well as in other areas. Traditionally, most of the residual zones within the Timor Sea have been attributed to fault seal reactivation and failure. However, the simulated early gas cap in the Jabiru structure has formed as a result of gas exsolution as the migrating hydrocarbons entered the Jabiru trap (and its shallow flanks), which was then only located a few hundred metres below the surface. The rapidly decreasing pressure allowed the gas to form a separate phase, with the result that in the Early Cretaceous, in the 3D model, the Jabiru trap was composed of a relatively large gas cap with a thinner (“black oil”) oil leg. Progressive burial through the Tertiary, and the attendant increase in pressure, resulted in the gas going back into solution. The associated decrease in the bulk volume of the hydrocarbon accumulation produced a “residual” oil zone at the base of the column, purely through a change in phase, rather than through loss of hydrocarbons from fault seal failure, for example. The processes outlined in this scenario would be essentially indistinguishable from those produced by fault seal failure when assessing traps using fluid history tools such as GOI. Such a process could be critically important in the case of shallow, low-relief traps, where only the exsolved gas could be trapped, with the “black oil” component displaced below the spill of the trap. Small, sub-commercial gas fields would thus be located around the periphery of the source depocentres - though these would be the result of an early, rather than late, gas charge. Small black oil accumulations could be developed inboard from such gas fields. A new method to extract HRDZs from 3D seismic data has predicted the location of new HRDZs in the northern Vulcan Sub-basin. Further investigation is needed to confirm/refine the method but it has the potential to significantly aid HRDZ mapping (and seal assessment and hydrocarbon migration studies). A workflow for future studies is proposed which includes inputs from basin modelling, leakage and seepage mapping, and fault seal and fault reactivation studies. Implementation of this workflow should ultimately allow a more reliable estimation of GOR prior to drilling.

Abstract:
The Late Devonian-Early Carboniferous Drummond Basin and overlying Late Carboniferous-Middle Triassic Galilee Basin are extensive intracratonic basins with predominantly fluvial sediment infill. They are inferred to have developed on Proterozoic and Early Palaeozoic basement similar to the adjacent Charters Towers Province and Anakie Inlier. Depositional and structural architecture of the basins have been investigated through a combination of seismic, geophysical well log and gravity data sets with lithologic information obtain from well cores, surface mapping and sedimentary petrography. Comprehensive interpretation of 750 km of seismic traverse resulted in the recognition of eleven seismic facies, several of which have distinctive internal signatures, separated by reflection boundaries that can be traced basin wide. Lithologic and geophysical logs from sixteen wells and boreholes can be matched to seismic stratigraphic units and allow the basinal infill to be described in terms of the lithostratigraphic frameworks already established in the literature. The construction of structure contours for unit boundary surfaces has identified extensional structures associated with rift phases of basinal development and the pattern of thrust and thrust fold features associated with basin inversion. Eleven new structural features that have continuity through the Drummond and Galilee Basins have been defined and other features noted in the literature have been reinterpreted based on evidence from seismic profiles. The construction of isopachs for each unit has allowed tracking of basinal infill thickness trends through time. Analysis of geophysical and lithologic logs from petroleum wells and boreholes, augmented by sections documented from surface exposure has resulted in the recognition of some 16 discrete sequences, each based on a repeating pattern of three types of non-marine systems tract that mainly reflect basinal tectonics but also the influence of climate and eustatic sea level change. Both basins share a common style of sequence development that is not reflected in the current literature. Provenance interpretation based on petrographic data from 121 thin sections representative of most of the Drummond Basin and all of the Galilee Basin suggests that the majority of basin infill was derived from a recycled cratonic source, such as the Thomson Fold Bel to the west, and less material derived from an eastern volcanic arc than previously thought. However SHRIMP-derived U-Pb age data for zircon populations from two samples broadly representative of quartz arenites prominent in the basinal successions conflict with this view. Such data for a sample from the Mount Hall Formation of the Drummond Basin indicates that its source was largely from Early to Mid Palaeozoic igneous terranes like those represented in the Charters Towers Province to the north and inferred for the Thomson Fold Belt to the west. Zircon ages of a sample of Warang Sandstone of the Galilee Basin indicates a Late Palaeozoic igneous source, with derivation largely from an eastern magmatic arc. The Drummond Basin commenced as a back-arc extensional basin, progressed through a thermal sag phase and ceased development during mild compression associated with a far-field expression of the Kanimblan Orogeny. Structural patterns show initial rift architecture, with compartments separated by newly defined transfer fault zones. Extensional faults between the transfer structures extend further through the basinal succession than previously thought. This basin developed a broad sag phase but the final stages show a foreland influence induced by Kanimblan thrust loading on its eastern margin. Basinal structure has been strongly modified by inversion in the Middle Triassic associated with the Hunter-Bowen Orogeny. The Galilee Basin commenced as a foreland basin expressing continuity with the late-stage development of the underlying Drummond Basin from which its division is arbitrary and based on historical misconceptions of Kanimblan tectonism. Thermal subsidence related to the rift phase of the Drummond Basin continued as an influence in addition to foreland subsidence. Tectonic quiescence marks a mid-stage of basinal development reflected in a regionally developed paraconformity and deposition of a basinwide coal measure sequence related to eustatic sea level rise over a stable substrate. The upper part of Galilee Basin infill reflects a foreland phase of development and records two episodes of thrust loading on the eastern margin associated with the Hunter-Bowen Orogeny. Ongoing crustal contraction during the Hunter-Bowen Orogeny resulted in inversion of the Drummond and Galilee Basins with the development of large-scale thrust dislocations and associated fault bend anticlinal structures. The Middle Triassic Clematis Group is the youngest unit that shows folding due to inversion. Much of the western parts of both basins remain relatively undisturbed apart from gentle regional pre-Middle Jurassic tilting that marked the final phase of Hunter-Bowen tectonism.

Abstract:
Four dynamic processes interact to create the stratigraphic record in a basin: climate, sediment supply, eustasy, and subsidence. To identify the contribution of each of these processes, techniques that can uniquely separate the effect of each component process on the stratigraphic record must be applied to produce a thorough understanding of the process, how it evolves through time and interacts with other processes. Recently published techniques (sequence stratigraphy, one- and three-dimensional backstripping), as well as techniques developed herein (Relational Tectonic Analysis), provide high resolution basin eustatic and tectonic histories. Integrating these new techniques with standard stratigraphic methods illuminates aspects of basin evolution heretofore hypothesized but unrecognized. Application of integrated analysis techniques indicates that plate tectonic reorganization events occurring during the Cretaceous Period had profound effects on the recognition of important sequence stratigraphic surfaces in southeastern and northwestern Australia. Seven reorganization events are recognized to have influenced the Cretaceous motion history of Australia. Eleven third-order eustatic cycles are recognized to have occurred during deposition of the Neocomian sediments of the Exmouth Plateau/North West Shelf. Sixteen third-order eustatic cycles are defined in Late Cretaceous sediments of the Otway Basin. The numeric ages determined from these twenty-seven biochronostratigraphically dated eustatic cycles are used to produce one- and three-dimensional subsidence histories. Each tectonic event creates a paired increased subsidence-decreased subsidence cycle. Each change in subsidence induces changes in the space available for sediment deposition. Changes in subsidence that create more space for sediments causes depositional systems to retrograde and transgressing the continent. Transgressive aspects of sediments deposited during each sea level rise associated with third-order eustatic cycle are amplified and therefore easier to recognize. Concurrently, the ability to recognize the regressive aspects of each eustatic cycle is diminished. If subsidence change reduces space available for sediments, the opposite effect occurs: depositional systems prograde, and regressive aspects of the third-order cycles are enhanced. Not all subsidence rate changes are due to tectonic reorganizations. Change in flexural subsidence induced by sudden large localized sediment influxes also cause enhancement of aspects of third-order eustatic depositional patterns.
