Abstract:
Summary Sarawak Shell Berhad has a number of offshore gas fields that produce from the Luconia carbonate formation, which can exhibit high-compressibility pore-collapse deformation. Recent accelerated subsidence has been observed at several of these fields, which extrapolates to final subsidence values well above previous estimates. This paper describes a geomechanical study involving core work to determine if the Luconia formation compressibility is sensitive to brine flow from the rising aquifer and a 3D geomechanical finite-element model developed to predict future subsidence and lateral movements for the F23 platform. Compaction tests were performed on the Luconia core from three different gas fields. Tests on twin plugs were conducted—one plug undergoing a standard uniaxial zero-lateral-strain compaction test, while its twin has several pore volumes of simulated-formation brine flowed through it (at virgin in-situ stress conditions) before the compaction loading. Four sets of compaction tests on twin plugs were completed. The higher-porosity samples showed characteristic pore-collapse behavior consistent with previous measurements on Luconia mouldic limestone core. No sensitivity to brine flow was observed. In-situ compaction logs in the field also do not show increased compressibility in sections flooded by the rising gas-water contact (GWC). The geomechanical model uses a relatively simple structural model comprised of four layers—two overburden formations, the Luconia carbonate and one underburden formation. A nonlinear deformation model for the Luconia formation captures the accelerating pore-collapse response observed in the core and in-situ compaction measurements. The model is calibrated to GPS-measured platform subsidence and is consistent with measured core- and field-compaction properties. The results predict that platform subsidence rates with depletion would level off, with a maximum subsidence of 18.5 ft +/- 1 ft at an abandonment pressure of 300 psi. Platform subsidence in the two years following the work continues to follow the predicted values. This work illustrates the importance of integrated geomechanical core testing, field-monitoring measurements, and modeling to accurately predict compaction and subsidence effects in highly compacting environments.

Abstract:
Across the Luconia continental shelf, the nature and structures of the crust are lacking geological understanding and precise characterization. Newly acquired, aeromagnetic, and airborne gravity data were used to assess deep and shallow sub-surface signals within the Central Luconia Province, off the coast of Sarawak, offshore Malaysia. Regional aeromagnetic anomalies appear to primarily reflect deep crustal features while depth (Z) tensors of airborne gravity anomalies evidence shallow subsurface structures. Strike directions of the interpreted structural trend on aeromagnetic and airborne gravity anomalies maps are measured and plotted into rose diagrams to distinguish the structural orientations for all datasets. Signature patterns extracted from the depth profiles were correlated with parallel seismic lines and nearest exploration wells and coincide well with the top of carbonate for Cycle IV/V and structures seen within the Cycle I and II sediments. The orientation of faults/lineaments at shallower depth is dominated by a NW-SE orientation, similar with the faults extracted from two recently published structural maps. Deeper subsurface sections yielded E-W to NWW-SEE dominant directions which were never presented in the published literature. The E-W oriented anomalies are postulated to represent the remnants of the accretion between the Luconia crustal block and southern boundary of the Palawan block. The NW-SE trend follows the same direction as prominent faults in the region. The insight into shallow and deep subsurface structures in Central Luconia Province imaged through airborne gravity and aeromagnetic data should provide guidelines and complementary information for regional structural studies for this area, particularly in combination with detailed seismic interpretation. Further evaluation on the response of Air-FTG® gravity and aeromagnetic could lead to the zonation of potential basement highs and hydrocarbon prospects in this area.

Abstract:
Reducing velocity inaccuracy in complex settings is of paramount importance for limiting structural uncertainties, therefore helping the geologic interpretation and reservoir characterization. Shallow velocity variations due, for instance, to gas accumulations or carbonate reefs, are a common issue offshore Malaysia. These velocity variations are difficult to image through standard reflection-based velocity model building. We have applied full-waveform inversion (FWI) to better characterize the upper part of the earth model for a shallow-water field, located in the Central Luconia Basin offshore Sarawak. We have inverted a narrow-azimuth data set with a maximum inline offset of 4.4 km. Thanks to dedicated broadband preprocessing of the data set, we could enhance the signal-to-noise ratio in the 2.5–10 Hz frequency band. We then applied a multiparameter FWI to estimate the background normal moveout velocity and the [Formula: see text]-parameter. Full-waveform inversion together with broadband data processing has helped to better define the faults and resolve the thin layers in the shallow clastic section. The improvements in the velocity model brought by FWI lead to an improved image of the structural closure and flanks. Moreover, the increased velocity resolution helps in distinguishing between two different geologic interpretations.

Abstract:
An update of the geothermal gradient and heat flow maps for offshore Malaysia based on oil and gas industry data is long overdue. In this article we present an update based on available data and information compiled from PETRONAS and operator archives. More than 600 new datapoints calculated from bottom-hole temperature (BHT) data from oil and gas wells were added to the compilation, along with 165 datapoints from heat flow probe measurements at the seabed in the deep-water areas off Sarawak and Sabah. The heat flow probe surveys also provided direct measurements of seabed sediment thermal conductivity. For the calculation of heat flows from the BHT-based temperature gradients, empirical relationships between sediment thermal conductivity and burial depth were derived from thermal conductivity measurements of core samples in oil/gas wells (in the Malay Basin) and from ODP and IODP drillholes (as analogues for Sarawak and Sabah basins). The results of this study further enhanced our insights into the similarities and differences between the various basins and their relationships to tectonic settings. The Malay Basin has relatively high geothermal gradients (average ~47 °C/km). Higher gradients in the basin centre are attributed to crustal thinning due to extension. The Sarawak Basin has similar above-average geothermal gradients (~45 °C/km), whereas the Baram Delta area and the Sabah Shelf have considerably lower gradients (~29 to ~34 °C/km). These differences are attributed to the underlying tectonic settings; the Sarawak Shelf, like the Malay Basin, is underlain by an extensional terrane, whereas the Sabah Basin and Baram Delta east of the West Baram Line are underlain by a former collisional margin (between Dangerous Grounds rifted terrane and Sabah). The deep-water areas off Sarawak and Sabah (North Luconia and Sabah Platform) show relatively high geothermal gradients overall, averaging 80 °C/km in North Luconia and 87 °C/km in the Sabah Platform. The higher heat flows in the deep-water areas are consistent with the region being underlain by extended continental terrane of the South China Sea margin. From the thermal conductivity models established in this study, the average heat flows are: Malay Basin (92 mW/m2), Sarawak Shelf (95 mW/m2) and Sabah Shelf (79 mW/m2). In addition, the average heat flows for the deep-water areas are as follows: Sabah deep-water fold-thrust belt (66 mW/m2), Sabah Trough (42 mW/m2), Sabah Platform (63 mW/m2) and North Luconia (60 mW/m2).

Abstract:
Central Luconia Province displays various structures in different parts of the basin attributed to extensional, strike-slip, and wrench tectonics. This affected the growth of the EX carbonate platform, the heterogeneity of carbonate facies, and lithological properties variations in the EX field. Such complexities restrict the understanding of the structures and sediments and may lead to well placement problems during a development stage. This research aims to study the carbonate growth of the EX field in accordance with the structural deformation and to analyse the field’s sedimentology. Detailed research of the structures in the EX carbonate platform was done using seismic interpretation to determine the nature of the relationship between faults and carbonate formation. Concurrently, a comprehensive sedimentary analysis was conducted using core and thin section studies to interpret facies characterization and depositional environment. The spectral decomposition attribute was used to study the seismic response of the lithologies in this field by demonstrating the anomalies of the carbonate platform using frequencies ranging from 328 Hz to 356 Hz. This research contributed to the interpretation of individual faults and the generation of a conceptual growth and structural model based on a seismic, attribute, and structural interpretation. The anomalies were used to identify the EX carbonate body and features such as the rim of the build-up through the spectral decomposition attribute. The sedimentary analysis from the EX-4 well also improved facies distribution and depositional environment, ranging from a deeper lagoon to a reef environment. This research can be used as an input for further correlation studies of the Central Luconia basin at a regional scale.

Abstract:
Des données sismiques, gravimétriques, de puits et d'affleurement sont intégrées pour étudier la structure crustale et l'évolution tectono-sédimentaire de la marge nord-est de la mer de Chine méridionale (NE SCS) ainsi que les implications pour l'évolution géodynamique des mers marginales. Les résultats illustrent la structure crustale contrastée de la marge étirée du NE SCS, comprenant un domaine proximal (Système de rift septentrional), d’étranglement (Bassin de Tainan) et distal (Southern Rift System - SRS et Southern High - SH). Le SRS est caractérisé par une forme en V, est séparé du domaine océanique par le SH, un domaine crustal moins aminci. Les résultats d’analyses géophysiques suggèrent que la croûte du SH a enregistré un magmatisme polyphasé durant la période pré- à post-rift. L’investigation du contexte paléogéographique pré-rift suggère que le SRS s'est formé au moins en partie le long de l'ancienne zone de suture entre l'Eurasie et le Bloc de Luconia. Les corrélations entre les domaines proximaux et distaux ont permis de discrétiser les principales étapes tectono-sédimentaires cénozoïques suivantes, qui enregistrent l'évolution syn-rift (fin du Paléocène à au début de l’Oligocène), post-rift (début de l’Oligocène à la fin du Miocène) et l'évolution liée à la formation du bassin d'avant-pays (fin du Miocène à aujourd'hui). Une analyse préliminaire de la géologie à Taïwan a permis de proposer des corrélations terre-mer entre certaines unités orogéniques et les domaines de rift du NE SCS. Ces observations ont été utilisées, conjointement avec les corrélations proximal-distal et l'analyse des faciès sismiques, pour déduire les environnements de dépôt des principales séquences sédimentaires du NE SCS
Seismic, gravity, well-log, and outcrop data are integrated to investigate the crustal structure and the tectonosedimentary evolution of the Northeast South China Sea Margin (NE SCS) and the implications for the geodynamic evolution of marginal seas. Results of this thesis show the contrasted crustal structure of the NE SCS rifted margin including its proximal (Northern Rift System), necking (Tainan Basin), and distal domains (Southern Rift System - SRS and Southern High - SH). Of particular interest is the presence of the V-shape aborted SRS that is separated from the oceanic domain by the relatively thicker SH. Quantitative geophysical analyses suggest that the crust of the SH recorded polyphase magmatism during pre- to post-rift time. Investigations of the pre-rift paleogeographic framework suggest that the SRS formed partly along the former suture zone between Eurasia and the Luconia Block. Proximal to distal correlations enabled the discretization of the main following Cenozoic tectono-sedimentary stages that record syn-rift (Late Paleocene to Early Oligocene), post-rift (Early Oligocene to Late Miocene), and foreland evolution (Late Miocene to recent). A preliminary analysis of the onshore geology of Taiwan enabled the proposition of onshore-offshore correlations between some orogenic units and rifted domains of the NE SCS. These observations have been used, with proximal-distal correlations and seismic facies analysis, to infer depositional environments for the main sedimentary sequences of the NE SCS

Abstract:
Aux confins maritimes du bas-poitou, lucon, ville episcopale, devient au xviie siecle un champ d'experimentation du renouveau catholique en france. L'impulsion est donnee par richelieu qui fait appel dans son diocese a de nouvelles congregations. Le bas-poitou devient terre de mission lorsqu'il favorise l'implantation des capucins et des lazaristes. Deux communautes educatives, les ursulines et l'union chretienne, contribuent a l'eradication de l'heresie protestante et a la formation de la jeunesse poitevine. Menee sur deux siecles, cette etude permet de mieux cerner l'evolution de ces ordres religieux. Si le xviie siecle coincide avec une recherche de l'absolu de dieu, le xviiie, a l'inverse, connait des periodes difficiles au sein de l'eglise. Capucins et lazaristes voient leurs effectifs decroitre et leur mission evoluer. Seules les deux communautes feminines resistent aux crises du xviiie siecle. Bien mieux, leur importance grandit. L'education des elites provinciales leur procure eleves et novices. Regulateurs de la transmission des patrimoines, ces deux derniers ordres beneficient d'une augmentation du nombre de leurs religieuses. Nees a la suite des guerres de religion, ces communautes disparaissent definitivement, de lucon, avec la revolution
On the coastal borders of bas-poitou, lucon, cathedral city, became an experimental field of france's catholic reneval in the xviith century. The impetus was given by richelieu who called on new congregations in his diocese. The bas-poitou became a land of missions when he favoured the settlment of the capucins and the lazaristes. Two educational communities, the ursulines and the union chretienne, contributed to the eradication of the protestant heresy and the education of the children of poitou covering two centuries, the study provides an insight into the development of these religious orders. Whereas the xviith century coincided with a quest of the absolute of god, the xviiith century went through hard times within the church. Capucins and lazarites saw their numbers shrinks, and their mission evolve. Only the two congregations of sisters resisted the crises of the xviiith century. More, their importance kept growing. The education of the provincial elites supplied them with pupils and novices. As regulators of the bequest of patrimonies, these two orders enjoyed a rise in the number of their nuns. Born after the wars of religion, it was with the revolution that these communities disappeared for good from lucon

Abstract:
Inspired by the core-shell composite structures found in nature, a range of protein based composites have been developed. These materials were made using synthetic approaches, which utilized the native protein architecture as an initiation point and size constrained reaction vessel for the piecewise formation of the second material. In the first illustration of this approach, a protein-P t composite was formed, where the protein cage has been modified to include a metal binding moiety for improved synthesis of metallic P t nanoclusters, which were shown to be an active H ₂ catalyst. This composite was analyzed by native mass spectrometry to determine the number of P t ions bound prior to mineralization and to measure the distribution of species after mineralization, which provided a unique view into the mineralization process. The second illustration was a material synthesized using the cage-like protein architecture as an internal guiding synthetic scaffold for the formation of a coordination polymer core inside the protein cage. The construction of this coordination polymer was unusual in that unlike normal coordination polymer synthesis, coordination of the metal preceded formation the ditopic ligands, which were afterwards completed using azide-alkyne click chemistry. Finally, a collection of protein-polymer composites were developed, which utilized a living radical polymerization method, atom transfer radical polymerization, to form internal polymer cores. By labeling one of these protein-polymer constructs with a Gd based MRI contrast agent a material with vastly improved relaxivity was made. The development of each of these three types of composites served to improve our understanding of the natural systems, from which they are derived, and provide a basis for further development of advanced multicomponent nanomaterials.

Abstract:
Central Luconia is a geological province on the Sarawak Shelf characterized by a widespread occurrence of carbonates of (largely) middle to late Miocene age. These carbonates have been a target of petroleum exploration since the late 1960s, leading to the discovery and development of a world-class gas resource mainly supplying the global liquefied natural gas (LNG) market. Carbonate growth in Central Luconia was initiated during a major regional transgression related to accelerated subsidence from crustal stretching associated with the formation of the South China Sea. Similar carbonate developments are seen elsewhere along the margins of the South China Sea, but the scale of Central Luconia, in terms of the large number of carbonate edifices, is unique. After a short “learning” phase, exploration in Central Luconia readily became extremely successful in the early 1970s, although the hoped-for “big oil” did not materialize; instead, large quantities of, almost exclusively nonassociated, gas were found. Being an export gas play, exploration in Central Luconia has been dictated strongly by market demand and therefore has been discontinuous over time, with fairly long periods of only piecemeal activity or even complete inactivity. In recent years, through growing LNG demand and improved commercial incentives, the play has seen a remarkable revival in terms of both activity and success. Despite its maturity with over 100 exploration wells drilled, the play still has important gaps in understanding, notably with respect to prospect specific charge and retention issues, and as a result, some very significant late-stage discoveries were possible. The carbonates proper have been the least of the concern in the total exploration effort to date; virtually without exception, wells drilled found carbonate reservoir rock of adequate quality for production of gas.

Abstract:
This paper describes the deposition of Miocene carbonates around Sarawak in a tectono-stratigraphic framework. The onset, termination, and location of the two main carbonate units, the Subis or Lower Cycle II limestones and the Luconia limestone, were controlled by tectonic processes, each beginning with a subsidence event, and terminated by influxes of siliciclastic sediments due to hinterland uplift. New data are presented on the intra–late Miocene decline of Luconia Limestone platforms that is correlated to the uplift of onshore Sarawak (Tinjar Province) and renewed siliciclastic sedimentation, which is dated as being at the same time as major uplift in northern Borneo. Miocene sedimentation around Sarawak was controlled mostly by extensional tectonics with several rapid subsidence events, which produced transgressive unconformities with mappable focal areas. Away from these focal areas, the contrast in facies, before and after the event, gradually diminishes in a predictable manner. This property of the unconformity is governed by Walther’s Law in that one well or field section cannot be exempt from the mappable trends in facies contrast observed in surrounding wells. This relationship constrains the interpretation of seismic, mapping, and analytical data, as illustrated by an example of a misdated unconformity that previously violated this balance of facies change in space and time. The tectono-stratigraphic model is a refinement of an existing empirical scheme devised in the area, with units called “Cycles” (Cycles I to VIII). This evidence-based framework is argued to be a genetic description of depositional units that developed in a dynamically evolving depocenter, subject to geographic rotation and relative variations in sea level that were dependent on location. This shifting basin configuration precludes use of a passive margin sequence stratigraphic approach, which assumes and requires a constant proximal to distal sedimentary direction and steady basement subsidence.

Abstract:
Karst is a common phenomenon in carbonate buildups worldwide. It has significant economic effects on exploration, drilling, field development, and secondary recovery mechanisms. In Malaysia, over 250 Miocene carbonate buildups were mapped offshore in the Central Luconia province of Sarawak, and roughly 65 carbonate buildups have been drilled. Almost every field has encountered indications for high permeability zones likely associated with karst, such as mud losses and drill bit drop during drilling activities; some fields were left abandoned due to mud losses that could not be controlled. Hence, it is important to predict and avoid karst features while drilling, during field operations, and for future carbon dioxide storage, to reduce development costs. The geometry, distribution, and dimension of karst structures in Central Luconia fields remain poorly known, as there have been very few systematic studies conducted. This paper provides a comprehensive characterization of karst features typical of Miocene carbonate buildups. The analysis was based on core and thin-section description, well-log characterization, and seismic spectral decomposition attribute interpretation. Importantly, the subsurface description is supplemented with the analysis of drilling parameters of some 68 wells from 36 carbonate buildups located across the Central Luconia province. A total of 51 wells encountered mud losses of varying intensities, which have been classified and plotted on maps. Loss circulation depths were recorded and compared to core samples that showed characteristics indicative of dissolution and exposure, such as chalkified texture, and were marked on well logs, which often showed unusually high porosity readings in the karstified intervals. All possible karst intervals were documented for further detailed seismic interpretation. Seismic spectral decomposition attributes techniques were applied to seismic data of Jintan and F6 platforms in order to map karst features, which were observed to be dendritic, round, and elongated patterns of several hundred meters in diameter and tens of meters deep. These features are particularly well-developed below backstepping external buildup geomorphology. The analysis showed that particularly strong losses occurred in stratigraphic intervals located toward the center of buildups. These were predicted using seismic spectral decomposition attribute signatures of karst features. The most extensive buildups with the strongest karstification were observed in the central part of the Central Luconia province.

Abstract:
Isolated carbonate platforms are abundant and widespread in Cenozoic strata and in the present-day oceans of Southeast Asia. The purposes of this article are (1) to describe the basic oceanographic setting of present-day Southeast Asia oceans; (2) to synthesize, compare, and contrast observations of the character of extant platforms in the context of fundamental oceanographic controls; and (3) to leverage these insights to develop a more complete understanding of older isolated platforms, especially the Miocene systems of Central Luconia. The data, presented to mimic an offshore-to-nearshore transect, illustrate Holocene platforms with a spectrum of sizes, depositional relief, facies abundances, and water depths. Although the first-order patterns of relief, size, and orientation are controlled by the geologic setting and Pleistocene history, the results demonstrate the influences of physical processes (waves, tides, currents), siliciclastic sediment, and chemical oceanography (nutrients, salinity, temperature) on the sedimentologic and geomorphic character of these platforms. Careful and critical application of these concepts to Central Luconia reservoirs in isolated carbonate platforms provides actualistic examples and process-response analogs. Although these perspectives offer understanding into controls on horizontal and vertical reservoir heterogeneities, they also emphasize that any one modern system can only be a partial analog for an ancient reservoir in an isolated carbonate platform.

Abstract:
A generic strategy for modelling gas fields in Miocene isolated carbonate platforms leverages insights from over 20 analogue fields in the Central Luconia Province in Malaysia, some with 30+ years of development and production history. The strategy advocates customizing modelling efforts to answer the questions required to make business decisions at hand (decision-based modelling) while keeping the models as simple as possible (fit-for-decision models). Four presented examples vary from (1) a conceptual, scaled simulation model that is used to investigate various host tie-back options (screening development options—two examples), through (2) a static reservoir model with seismically constrained reservoir properties combined with a simulation that uses local multipliers to test the impact of key heterogeneities on well-placement options (development optimization), to (3) a full-field static and dynamic reservoir model that is matched to a long and detailed production history to accurately forecast late-field-life gas and water production (wells, reservoir, and facilities management). In combination with standardized work flows for reservoir property modelling, the strategy shifts the modelling focus from elaborate base-case models with uncertainty ranges to testing multiple scenarios that span the range of possible outcomes. The use of this generic modelling strategy has led to faster turnaround of subsurface work, enabling faster development and asset management decisions. Although the examples presented in this paper are specific to Miocene carbonates in Central Luconia, a similar strategy could be suitable for other geological settings.

Abstract:
Middle to late Miocene carbonates from Central Luconia, offshore Sarawak, Malaysia, contain significant hydrocarbon reserves. However, the complex pore system of the carbonate reservoir poses drilling and production challenges, such as water coning. Moreover, capturing and storing CO2 in depleted carbonate buildups requires the pore type architecture to be well understood. The aim of this study was to investigate pore types in a stratigraphic context and to propose a 3D conceptual model of the pore type distribution. The case study discussed here is the E11 Field. E11 is considered the type location for Central Luconia carbonates because of its unique, almost complete core coverage. The data used for this study included a 3D seismic volume, core descriptions, together with petrographic and petrophysical data. The workflow used involved partitioning the buildup into specific lithofacies, pore, and cement types within stratigraphic sequences and depositional environments. Results show that the E11 Field represents a coral and foraminifera-dominated isolated carbonate platform. Fifteen lithofacies and ten microfacies were identified. Paragenetic alterations include five stages of calcite cement, three stages of dolomite cement, one stage of dedolomite, and a minor stage of pyrite mineralization. Diagenetic changes took place in various environments ranging from early marine phreatic, to mixed meteoric-marine, to meteoric realms. Minor burial diagenesis led to the formation of late-stage cements. Early diagenetic alterations closely resemble the primary facies arrangement in distinct environments of deposition and stratigraphic sequences. Interestingly, these sequences mimic in places distinct changes of the seismic geomorphology of buildups. In particular, the middle to upper Miocene boundary (TF2/TF3) coincides approximately with a major reduction in buildup diameter. This backstep corresponds to a meter-thick, low-porosity flooding interval observed in the core of the E11 buildup. Tight (low-porous) layers in the E11 buildup mark the upper and lower boundaries of stratigraphic sequences and are partially traceable on seismic reflection data across the buildup. A lithological correlation across the E11 field showed that wells located near the inner, lagoonal part of the buildup are more prone to dolomitization and attract higher thicknesses of low-porosity flooding interval. The combination of depositional sequences, diagenetic phases, and seismic geomorphology allowed the buildup to be divided into six stratigraphic sequences, each approximately 50–70 m thick. These sequences can be compared to neighboring buildups and to regional stratigraphic sections using biostratigraphic and chemo-stratigraphic data. Larger benthic foraminifera; i.e., Miogypsina and Austrotrillina, are restricted to the middle Miocene stage “TF1” and “TF2” (where TF is a stage of the Tertiary Period), (19–11.1 Ma), whereas Amphistegina and Cycloclypeus are more indicative of the late Miocene stage TF3 (11.1–7.1 Ma). The biostratigraphic boundary TF2/TF3 was correlated with its strontium isotope signature. This allowed the age of the middle to late Miocene boundary to be estimated. These observations from the E11 buildup were synthesized in a conceptual depositional and diagenetic model. The description of E11 may serve as an analog for carbonate buildups elsewhere in Southeast Asia (Vietnam, Indonesia, and Philippines) and aid in the proposed CO2 storage project.

Abstract:
Estimating the geometry and sedimentary heterogeneities of carbonate platforms is a very challenging task. In recent decades, numerical stratigraphic forward models have been developed to provide a quantitative view of sedimentary processes with the resulting stratigraphic architecture. Although used in many academic and industrial studies, this numerical approach is rarely used in everyday exploration and appraisal workflows. The calibration of these models on available seismic and well data is indeed a challenging and time-consuming process. Here we use the DionisosFlow model to simulate a carbonate platform typical of the Miocene formations observed in Central Luconia, South China Sea. We build a reference simulation or virtual ground truth from literature data, using for instance the Haq et al. (1988), Laskar et al. (2011), and Bosscher and Schlager (1992) curves, which prove indications on sea-level variations, orbital parameters, and carbonate production as a function of water depth, respectively. We analyze the sensitivity of the simulation results to the parameters controlling the physical processes: accommodation space creation, carbonate production, and sediment transport. Results show that stratigraphic modeling makes it possible to test the concepts of sequence stratigraphy in a virtual digital world, thus opening the possibility of testing the sensitivity of the different characteristics of a sedimentary system to physical parameters. We also propose an innovative approach to using this stratigraphic modeling in operational cases. The first step is to identify a diachronous geological body such as the carbonate platform sensu stricto, which is easily identifiable using seismic data. A comparison of the geometry of this geological body with the thickness maps derived from the seismic interpretation provides a first regional metric controlling the shape of the studied sedimentary systems. The second step is to validate the simulation results with well data, and, in particular, facies from the log interpretation. The computation of vertical proportion curves (VPC) in the vicinity of wells facilitates understanding the local variability of facies in the digital world as well as in the real world. This second metric, based on a comparison of VPCs, makes it possible to assess sequences and sedimentary heterogeneities and to define much smoother cost functions, thus facilitating the use of automatic optimization algorithms. In conclusion, this work shows that numerical stratigraphic forward modeling is a tool that reproduces stratigraphic concepts using simple physical laws. Through the use of well and seismic metrics adapted to the resolution of the model, use of this numerical approach in daily exploration work to complement the interpretation of seismic and well data provides a quantitative stratigraphic view of the studied area to better access uncertainties and risk in exploration.

Abstract:
Abstract High CO2 encountered in various wells throughout Sarawak basin have always been area of concern for both exploration and development. As the contaminants negatively impact economic value as well as hinders our commitment toward net zero carbon, understanding the source of these requires critical and urgent attention. This paper presents an integrated basin scale petroleum system modelling approach to understand source, generation, and distribution of CO2 in Sarawak offshore. A regional scale CO2 Model in Sarawak Basin is constructed covering West Luconia, Central Luconia, Tatau, and Balingian area. A comprehensive Petroleum System Model is generated integrating geophysical, geological and well data to predict concentration and risk of CO2 in Sarawak Basin. The model incorporates contribution from both organic and inorganic CO2 sources to understand generation and charge evolution histories.
