Early sequence stratigraphic models emphasised the use of sequence stratigraphic surfaces for identifying and constraining the stratigraphic position of reservoir intervals at large scales (100s-1 000s of metres) using mostly seismic reflection data. In contrast, reservoir development focuses on resolving smallscale, largely lateral changes in reservoir quality and distribution where the stratigraphic position of the reservoir interval is generally already well defined. Also, due to the scale of analysis, the database for reservoir development studies commonly consists exclusively of well data (i.e. fullhole cores, wireline logs and image logs); fluid flow properties can be measured directly using the same data types that are employed to identify and map key surfaces. Despite well documented successes of the sequence stratigraphic approach at exploration scales, little information exists regarding the utility of sequence stratigraphic approach for reservoir development. This study investigates the utility of the sequence stratigraphic approach for aiding reservoir development of the Wyandra Sandstone Member at Tarbat-lpundu Field, Southwest Queensland. A sequence stratigraphic framework was constructed for the Wyandra Sandstone Member using a database of core, wireline suites, image logs, palynological data and modern analogues. The utility of the sequence stratigraphic framework for reservoir development was then evaluated using petrography and measurements of fluid flow properties from conventional core analysis and wireline logs. The Wyandra Sandstone Member is a -20m thick, volcaniclastic sandstone sheet that forms a fining-upward succession. Despite relative lithologic homogeneity, the sandstone sheet is characterised by severe variations in fluid flow properties stemming from complex patterns of diagenetic porosity/permeability occlusion and enhancement. A grain size control on the occurrence and intensity of secondary dissolution suggests that an understanding of grain size distribution within the_ Wyandra Sandstone Member is central to resolving reservoir heterogeneity. Sequence stratigraphic divisions of the Wyandra Sandstone Member indicate that it formed in response to a high-order regressive - transgressive cycle driven by glacio-eustatic fluctuation coupled with variation in the rate of basin subsidence from the Barremian to the Aptian. Seventy-three percent of reservoir rock within the Cadna-owie Formation is confined to the lower, fluvially dominated portion of the Wyandra Sandstone Member that is interpreted to represent a lowstand systems tract. However, the identification of the lowstand systems tract, in itself, is of limited value for reservoir development. Several uneconomic development wells have intersected low permeability sandstone within the lowstand systems tract. The largely lateral variations in reservoir properties within the lowstand systems tract of the Wyandra Sandstone Member stem from the partitioning of medium- to very coarse-grained sandstone to channelised fluvial distributary deposits. Although sandstone of fluvial distributary deposits show a range of fluid flow properties (0.01->1000mD), secondary dissolution of chemically unstable framework grains, authigenic clay and carbonate cement occurs preferentially in areas of intense channel amalgamation. These areas are interpreted as major fluvial axes similar to those that occur at the 'fan apex' of modern depositional systems of the Great Artesian Basin and modern transverse depositional systems occurring along strike-slip faults. The position of the major fluvial axes are interpreted to be controlled by localised changes in the style of basement faulting and related patterns of differential compaction in the overlying cover units. Mapping sequence stratigraphic surfaces, as distinct from lithologic surfaces, in the Cadna-owie Formation defines linkages of contemporaneous depositional systems. Consequently, the sequence stratigraphic divisions are compatible with studies of modern depositional systems, whereas lithologic divisions of the Cadnaowie Formation generally are not. As a result, a variety of analyses conducted with respect to sequence stratigraphic divisions, and particularly the utilisation of modern analogues, improves our understanding of the sedimentological processes operative during deposition of the Wyandra Sandstone Member. It is hoped that the conclusions stemming from this study provide a basis for more accurately accessing the development risk at Tarbat-lpundu Field.

Annotation:

The general objectives of the study are to assess the applicability of sequence stratigraphic concepts to non-marine deposition in a large intracratonic basin and to determine fundamental controls that affect the stratal architectures of this basin. During the last two decades, sequence stratigraphy has been emerging as a powerful tool to analyze marine sedimentary successions and has been successfully applied in many petroleum exploration programs. However, at present, there is still some debate as to the applicability of sequence stratigraphic concepts to non-marine successions. The early works in sequence stratigraphy (i.e. Vail et. al. 1977; Posamentier and Vail, 1988; Galloway, 1989) focused on passive continental margin settings. In these settings, eustatic change of sea level (such as published by Haq et. al., 1988) is the major factor in determining the facies architecture and stacking patterns of sedimentary rock strata. The model derived from these studies has often been used (or abused!) as a template for exploration works in marginal marine basins (Posamentier and James, 1993). Later it was realized that the concepts of sequence stratigraphy could also be applied to the study of sedimentary strata of non marine basins (e.g. Shanley and McCabe, 1993; Legaretta et al., 1993; Blum, 1993, among others) where global sea level change has little, if any, effect on the processes of sedimentation. Although the basic concepts of sequence stratigraphy, the control of sediment supply and accommodation, are valid in all basin settings, the specific models and schematic sections for marginal marine basins certainly need to be modified before being applied to basins that are isolated from the sea (Weimer, 1992; Posamentier and James, 1993).

Inter-aquifer mixing studies are usually made carrying out hydrochemical and isotopic techniques only. In this thesis these techniques have been integrated with three-dimensional geological modelling proving to be a better approach for inter—aquifer mixing assessment in regional areas, and also highlighting the influence of faulting in the understanding of groundwater and gas migration, which could not be possible using the two fist techniques alone. The results are of particular interest for coal seam gas basins and can even be used as exploration tools as areas of higher permeability and gas migration were identified.

Annotation:

This study integrates sequence stratigraphy of the Late Permian Toolachee Formation in the non-marine intracratonic Permian-Triassic Cooper Basin, Australia with 3-D seismic attribute analysis to predict the extent of depositional environments identified on wireline and well core data. The low resolution seismic data (tuning thickness 23 - 31 m) comprised of six seismic horizons allowed the successful testing of sequence stratigraphic interpretations of the productive Toolachee Formation that were based on wireline data. The analysis of 29 well logs and three 20 m core intervals resulted in the identification of eleven parasequences that comprise the building blocks of an overall transitional systems tract, characterised by a gradual increase in accommodation. The parasequences reflect cyclic transitions between braided and meandering fluvial systems as a result of fluctuations in sediment flux, possibly driven by Milankovitch climatic-forcing. The seismic horizon attribute maps image mostly the meandering fluvial bodies within the upper parts of the parasequences, but some maps image the lower amalgamated sand sheets and show no channel structures. Categorisation of the fluvial bodies in the overbank successions reflects a gradual decrease in sinuosity, channel width, and channel belt width up-section, supporting the overall increase in accommodation up-section. Similar acoustic impedance values for shales and sands do not suggest successful seismic forward modelling between the two lithologies. Geological interpretations suggest most imaged channel fill to be made up predominantly of fine sediments, as channel avulsion and abandonment is common and increases with time. Seismic forward modelling resulted in the interpretation of carbonaceous shale as a possible channel fill, supporting the geological interpretations. The three major identified fluvial styles; braided, meanders, and distributaries are potential targets for future exploration. Extensive sand sheets deposited from braided fluvial systems require structural traps for closure. Meandering and anastomosing channel systems represent excellent stratigraphic traps, such as the basal sands/gravels of laterally accreted point bars.

Annotation:

The Eromanga Basin hosts the Early Cretaceous reservoir sediments of the Murta Formation and its basal McKinlay Member of prograding fluvio-lacustrine and deltaic origin that are characterized by low oil production and recovery factors which are heavily controlled by depositional facies. The integration of the concepts of facies associations, sequence stratigraphy and petrography enabled this study to map the continuity of the Murta Formation and to point out the effect of the diagenetic features on the reservoir quality. The diagenetic effects and spatial distribution of the depositional facies in the basin are essential in nominating locations of good quality reservoirs. The aims of this study were: to characterize the chronostratigraphic depositional facies and distribution, to examine the affect of diagenesis on reservoir quality and to define those parts of the basin where potential reservoir sands are likely to be found. A detailed analysis of depositional facies in the Murta Formation and its basal McKinlay Member was based on drill core analysis and regional wireline log correlations. The application of non-marine sequence stratigraphic concepts to the wireline logs and core description data have led to the identification of 7 chronostratigraphic units. This data was used in constructing a series of schematic palaeogeographic and isopach maps of the study area to predict the changes in depositional styles with time and space. Six depositional facies were identified in the study area with overall fine-grained sandstones, siltstones and mudstones. These depositional facies include; distributary channels, shoreline, protected shoreline, deltaic mouth bars, tempestites and turbidites deposits. One particular unit, the transgressive systems tracts of the McKinlay Member, (Unit 7) is the best target for reservoir development because of relatively high proportion of pay sands, medium to coarse-grained sand sizes and good reservoir quality with low diagenetic affects. High stand systems tract units 2, 3 and 5 are considered to be secondary reservoir targets because of diagenetic affects and their fine-grained character. Units 1, 4 and 6 are not considered of economic value for oil production because of their extremely low reservoir quality and muddy lithologies. The main diagenetic affects on sandstones (quartzarenites) in the study area are quartz overgrowths, formation of authigenic clay (kaolinite), carbonate cement (calcite and siderite), formation of microstylolites (pressure solution) and dissolution of the framework grains to form secondary pores. The McKinlay Member of the Murta Formation in South Australia consists mainly of medium to coarse-grained sandstones of distributary channel origin (facies association 1). It has the highest recorded porosity and permeability (9.5% and 36.8mD respectively). Shoreline, protected shoreline, deltaic mouth bars and tempestites deposits, mainly from Jackson-Naccowlah Trend wells in Queensland, are of finegrained sandstones (facies associations 2, 3, 4 and 5 respectively). They have adequate average porosity (7%), but the formation of microstylolites and associated mica parallel to the bedding planes inhibited vertical permeability and has been recorded to be as low as 3.1mD. Turbidites in the central basin are characterized by extremely low reservoir quality (2.6% and 0.25 mD) and muddy lithologies of facies association 6 that are severely degraded by diagenetic effects.

Despite the prolific hydrocarbon and geothermal potential within the Cooper-Eromanga Basin, the thermal history of the region has largely remained elusive. This study presents new fission track, U-Pb and rare earth geochemical data for apatite samples from five wells within the Cooper-Eromanga Basin. Based on these data, thermal history models were constructed and an apatite provenance study was carried out. The apatite samples taken from the upper Eromanga Basin sediments (Winton, Mackunda and Cadna Owie Formations) yielded a dominant population of early Cretaceous and minor population of late Permian – Triassic apatite ages that are (within error) equivalent to corresponding fission track age populations. Furthermore, the obtained Cretaceous apatite ages correlate well with the stratigraphic ages for each analysed formation, suggesting (1) little time lag between apatite exposure in the source region and sediment deposition; and (2) that no significant (>~100oC) reheating occurred after deposition. The apatites were likely distally sourced from an eastern Australian volcanic arc, (e.g. the Whitsunday Igneous Association), mixed with sediment sources from the New England and/or Mossman Orogens. Deeper samples (>2000m) from within the Cooper Basin (Toolachee Formation) yielded (partial) reset fission track ages, indicating heating to temperatures exceeding ~80-100oC after deposition. The associated thermal history models are broadly consistent with previous studies and suggest that maximum temperatures were reached at ~95-70 Ma as a result of progressive heating by sedimentary burial and/or radiogenic basement heat loss. The interpretation of subsequent late Cretaceous – Palaeogene cooling remains more enigmatic and may be related with enhanced thermal conductivity as a response to aquifer flow and/or cementation. Four of the five wells recorded a Neogene heating event: however, more data would be required to assess the significance of this more recent thermal perturbation.

The Cooper and Eromanga Basin is located in northeastern South Australia and southwestern Queensland. Nine samples from four fields within the SA sector of the Cooper-Eromanga Province along the southwestern Patchawarra Trough (Sellicks and Christies) and western Wooloo Trough (Worrior and Arwon) were analysed. The aromatic source and maturity cross plot of 1-MP/9-MP versus 2-MP/1-MP was used to determine the ratio of mixing between Permian- and Jurassic/Cretaceous-sourced hydrocarbon in oils. These oils from the Patchawarra Formation within the Sellicks Field has ~0.9% Rc and is a Family 2 Permian end-member, which has migrated a minimum distance of 23-24 km. This same oil contributes 60-70% of the input to the Birkhead and Hutton reservoirs in the Christies Field. The Jurassic input (~0.6% Rc) came from a Birkhead source located 15-30 km to the east. The Worrior and Arwon Fields contain mixed oils within Jurassic and Cretaceous reservoirs. Here the Permian input decreases up section (Hutton 70%, Birkhead 65%, McKinlay 60%) with the Permian Toolachee Formation and Jurassic Birkhead Formation being the likely source rocks. The minimum migration distance for the oil sourced within the Birkhead Formation is 4-5 km from the west and ~24 km from the east.

Annotation:

Exploration undercover presents a significant challenge and relies heavily on the effective interpretation of geophysical data. Magnetotelluric (MT) surveying is an ideal method for characterising these covered terranes because it provides resolution from the shallow cover into the deep earth. Undercover terranes often lack constraining information, creating a significant impediment for translating geophysical features into geological interpretations. This thesis presents advances for understanding MT inversion uncertainty to produce better geological interpretations in data-poor areas. The project area is along strike from major Pb-Zn-Ag deposits at Mount Isa and George Fischer, and includes the location of a proposed suture between the Mount Isa Province and the North Australian Craton. The structure is interpreted from potential field data by previous workers but is not observable in outcrop. The prospective Proterozoic packages are concealed beneath 200-1200 m of Phanerozoic cover and consequently exploration success in this area has been very poor. The project dataset contains 1600 audiomagnetotelluric (AMT; 10-4 to 100 seconds) and broadband MT (BBMT; 10-2 to 103 seconds) sites; with approximate survey dimensions of 90 km north-south with line spacing of 5 km, and 150 km east-west with inter-site spacing of 2 km. The project area has scarce geological and geophysical information, and there is an inadequate understanding of the macro-scale geological structure. Three studies were undertaken with the aim of creating a new geological interpretation for the area. These studies were based on quantifying inversion variability and integration of information during interpretation. One study presents a workflow to objectively assess the variability of models produced during 3D magnetotelluric inversion. The workflow uses a sequential inversion methodology to examine model variability while minimising the computational demand of 3D inversion. The results highlight the high degree of variability permissible in 3D MT inversion models and reinforce the clear impact inversion parameterisation has on the inversion models. Our method allows objective differentiation between well- and poorly-constrained features. The second study integrates the results of 3D magnetotelluric inversion and variability analysis from the previous study, with deep crustal seismic and potential field data to refine our understanding of the southern Mount Isa Province. A new crustal-scale west-dipping feature is identified that is adjacent to a major change in crustal thickness and associated with a major change in crustal resistivity (that extends at least 400 km to the north). There is additionally a conductor located on or just above the interface and significant changes in the potential field response corresponding to both upper crustal and lower crustal depths. The structure is spatially associated with a low-resistivity feature (interpreted to be due to fluid movement or alteration), extends into the shallow crust and represents a possible exploration target. The third study is focused on resolving the depth to basement and basin morphology of the Neoproterozoic-Mesozoic cover basins in the project area. Resolving the depth to basement from MT data is inherently difficult due to the data’s insensitivity to the top of a resistive package (such as crystalline basement rocks). We used a combination of 1D probabilistic inversion, 2D deterministic inversion and synthetic modelling of downhole resistivity data to produce the final interpretation. The interpretation includes the base of the Eromanga Basin, an intra-Georgina Basin low-resistivity layer and depth to basement, all of which have associated error estimates. Understanding variability in geophysical inversion is integral to the construction of a well-supported geological interpretation. This is especially true for areas where constraining information is limited or absent. We demonstrate that an understanding of data resolution and model uncertainty enables interpretation of new, worthwhile geological information from MT inversion even in data-poor greenfield terranes. Our new interpretation de-risks mineral exploration and provide new insights into crustal structures important for exploration targeting.

Comprehension of the character and stratigraphic architecture of sedimentary rocks in the subsurface is derived from the observation of modern depositional processes on the surface of the Earth and field-based studies of similar depositional systems exposed in outcrop. In Australia’s Eromanga Basin, the Murta Formation is a substantial hydrocarbon reservoir; however it does not outcrop, data from wells are sparse and the depositional setting has previously been interpreted to be both continental lacustrine and marginal marine. Through extensive field and laboratory work, both for the Murta Formation and depositional analogues, this study investigates and discusses the sedimentology, stratigraphy and provenance of the Murta Formation in the Eromanga Basin. Murta Formation sediments were deposited in the Lower Cretaceous during the Berriasian to Valanginian, a key time of increased variation in global eustacy, continental breakup, climate change and just after a catastrophic mass extinction event at the Jurassic-Cretaceous boundary. Core investigations reveal that the Murta Formation is primarily composed of fine sands and muds, often arranged in coarsening up parasequences that become increasingly sand-dominated up section. The Murta Formation thickens over the Patchawarra and Poolowanna troughs, suggesting a basin depocentre in this area. Two basin-wide transgressive-regressive events are interpreted to have occurred and these most likely correspond with marine incursion in the Upper Murta Formation as the Eromanga Basin transitioned from continental lacustrine to marginal marine conditions. Zircon data indicate that sediments are sourced from mature cratons and younger volcanic provinces. This implies that the potential for unexplored reservoir presence on the western side of the basin is substantial, as mature, clean sands in were most likely deposited there in proximal deltaic environments. This project was motivated by research questions arising from the discovery of the Cuisinier Field, which unexpectedly yielded hydrocarbons in a new facies type within the Murta Formation. Sands within the Cuisinier system most likely represent a delta system deposited during a basin-wide marine regression and transgression event. As data for the Murta Formation are sparse, fluvial terminations in low accommodation basins are not widely-studied and marine transgressions in epicontinental seaways tend to be complex, analogue studies were also conducted. Lake Yamma Yamma in central Australia was investigated as it includes a substantial area of fluvial termination deposits at the main lake inlet, and has a similarly low-gradient basin setting to that of the Murta Formation. The geomorphology and sedimentology of deposits at the Lake Yamma Yamma site were described in detail, and controls on deposition interpreted. Based on this analogue study and literature review, ideas around the theme of fluvial termination deposits in a low gradient basin setting were applied to interpretation of the Murta Formation. The Dakota Formation, deposited at the initiation of the Cretaceous Western Interior Seaway, in Colorado, USA, was considered in detail at a specific outcrop locality and used as an analogue for the Murta Formation because it comprises a net transgressive system preserving internal transgressive and regressive cycles. Overall, the transgression was complex and piecewise. The size and shape of the deltaic features are similar to those observed in core in the Murta Formation, so thus provide a useful indicator for likely facies arrangements, as well as reservoir connectivity and geometries in the Murta Formation. These new studies of deposits in modern and outcrop localities, in combination with published literature, allowed an improved facies model to be developed for the Murta Formation. They also provide new insights into previously unstudied deposits, and contribute to aspects of research focus that are presently understudied. Lake Yamma Yamma has not previously been the focus of any papers despite being the largest playa lake in Queensland, Australia, and containing a substantial dryland terminal fluvial deposit, features often interpreted in the ancient record but not well studied in modern environments. As a part of this research, a new classification scheme to aid in the description and interpretation of dryland fluvial termination deposits is proposed. Although the Dakota Formation has been the focus of previous studies, the particular locality studied in this thesis has not been described in detail or assigned a comprehensive stratigraphic framework. As well as providing a detailed description of the sedimentology and a stratigraphic framework for the study area, this study also contributes new detrital zircon ages, which enabled an improved understanding of regional paleogeography. Furthermore, deposits preserved as a result of transgressions of epicontinental seas are not well understood and with no observable modern analogues, the detailed process-based understanding contributed by this study is very important in understanding similar deposits in the subsurface. In addition to contributing new perspectives on the Murta Formation of the Eromanga Basin, dryland fluvial termination deposits and the Dakota Formation of the Western Interior Seaway, the results of this thesis will provide a useful resource for the interpretation of similar systems in the geologic record.

Regolith and sedimentary material overlying potentially enriched basement, is an ever-present obstacle in the highly prospective Olympic iron-oxide copper gold (IOCG) Province, South Australia. The Eromanga Basin, composed of Mesozoic sediments - Algebuckina Sandstone, Cadna-owie Formation and Bulldog Shale - overlies the northern extent of the Stuart Shelf, including the Olympic Dam IOCG province. The closest surface exposures of these sediments to Olympic Dam, is around the opal mining town of Andamooka. The formation and distribution of the precious opal has been previously linked to fluctuating water tables. However, oxidation of pyrite by fluctuating water table height, caused by intracontinental extensional faulting in the area, provides an enhanced interpretation linking opal distribution with the presence of jasper and silcrete lag. Extensional fault boundaries were identified through contrasting regolith and landform components observed from field mapping and remote sensing imagery. ASTER band ratios and relative absorption-band depth ratios complimented field observations with ratios primarily useful in distinguishing high reflectance homogenous mineral groups e.g. opal diggings and sand dunes. A regolith-landform map and digital elevation model over the area identifies the contrasting units, with opal diggings (digitised from ASTER imagery) strongly associated with higher elevations. The potential for secondary economic mineralisation is proposed for the Andamooka area. A source material (Olympic IOCG Province), transport mechanism (extensional duplex faulting), and potential trap rock (REDOX boundaries and varying permeability of Mesozoic units) all contributed to a prospective exploration model for the area.

The Eromanga Basin, a major Jurassic-Cretaceous intracratonic basin in eastern Australia, and the underlying Permo-Triassic Cooper Basin are examined from two perspectives - the subsidence history and the present day thermal state.The backstripping method for subsidence analysis is assessed for sensitivity to the porosity/depth relationship and it is shown that the overall shape of subsidence curves are not affected, although the absolute magnitude of the values will be different. Assumptions regarding palaeo bathymetry, sea level variations and isostatic models are likely to introduce more significant errors, especially to individual values. Tectonic subsidence curves were obtained for 40 wells in the region. The Permian was a period of dominantly fault controlled subsidence and the Triassic-Jurassic subsidence phase is consistent with a thermally driven mechanism. It is not possible to tightly constrain the thermal time constant (50-200 m.y.) or the time of initiation of subsidence (260-180 Ma) of this latter subsidence phase. An unconformity in the Late Triassic is attributed to processes at the eastern plate margin superimposed on the subsidence history as rather than a change in the formation mechanism of the two basins. During the Cretaceous the simple subsidence pattern was interrupted and the subsidence rate increased rapidly. This is attributed to a relatively rapid influx of sediment from an active volcanic arc to the east of the region. A simple model of excess sediment influx is presented which predicts the the observed sediment thicknesses and explains the departure from the thermal subsidence trend. The model predicts a topography up to 200 m above the present day observations and an additional subsidence mechanism needs to be invoked, possibly related to continental margin rifting or phase transformations beneath the basin. This mechanism is~ however, poorly constrained from the available information. The proposed excess sedimentation model provides an explanation for the transgressiveregressive nature of the Cretaceous sequence without appealing to global sea level changes or continent wide uplift. As vitrinite reflectance observations are commonly the only available constraint on the thermal evolution of a sedimentary basin. an examination of the discriminatory potential of such observations was made. An inversion procedure was developed and results with synthetic data suggest that the early heat flow history of the Eromanga/Cooper Basins could not be adequately constrained. The present day geothermal gradient in the central Eromanga Basin region is up to 60"C/km, considerably higher than average continental values. Divided bar measurements on core samples, combined with downhole lithology information lead to a depth averaged thermal conductivity value of 2.0-2.2 wm-1K-1. However, unlike the subsidence analysis, estimates of the thermal conductivity are sensitive to the assumed lithologies. A reasonable range for the heat flow is about 75-120 m wm-2. In some wells higher heat flow is associated with granitic basement. Numerical modelling of the steady state thermal regime implies that much of the central southern Cooper Basin is underlain by granite. Individual granites have been previously dated at between 10 and 60 m. y. older than the oldest sediments and provide evidence for a thermal event prior to the commencement of subsidence. One 39 Ar I 40 Ar age spectrum for a basement granite presently at nearly 200"C supports conclusions previously drawn from vitrinite reflectance and, more recently, apatite fission track analysis that the present day elevated thermal state is a relatively recent(< 10 Ma) phenomenon. No detailed examination of this feature was undertaken but qualitatively it is considered that advective, as opposed to conductive, heat transfer is active as there is no topographic expression of a deep heat source.
