Book excerpt: "The Capel and Faust basins are located over the northern part of the Lord Howe Rise, a large offshore frontier region containing a number of basins with untested petroleum prospectivity. Recent data acquisition by Geoscience Australia has significantly improved geological knowledge of these basins. Given the diversity of acquired data, comparative sparseness of data coverage, lack of deep drilling control, and complexity of geological structure, effective data integration and analysis methods were essential for a meaningful geological interpretation of the Capel and Faust basins. By using the 3D visualisation and modelling environment provided by GOCAD?, the datasets were captured, processed and interpreted to create an integrated 3D model that enabled key geological and prospectivity questions to be answered. This report summarises the construction methodology and the resulting geological and prospectivity implications of the Capel-Faust 3D geological model."--Executive summary.

This book was released on 2015-10-19 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continental margins and their fossilized analogues are important repositories of natural resources. With better processing techniques and increased availability of high-resolution seismic and potential field data, imaging of present-day continental margins and their embedded sedimentary basins has reached unprecedented levels of refinement and definition, as illustrated by examples described in this volume. This, in turn, has led to greatly improved geological, geodynamic and numerical models for the crustal and mantle processes involved in continental margin formation from the initial stages of rifting through continental rupture and break-up to development of a new ocean basin. Further informing these models, and contributing to a better understanding of the features imaged in the seismic and potential field data, are observations made on fossilized fragments of exhumed subcontinental mantle lithosphere and ocean–continent transition zones preserved in ophiolites and orogenic belts of both Palaeozoic and Mesozoic age from several different continents, including Europe, South Asia and Australasia.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, three-dimensional (3-D) basin and petroleum system modeling of the subsurface through geological time has evolved as a major research focus of both the petroleum industry and academia. The major oil companies have independently recognized the need for basin and petroleum system modeling to archive data, facilitate visualization of risk, convert static data into dynamic processed data, and provide an approach to evaluate potential prospects in oil and gas exploration. Basin and petroleum system modeling gives geoscientists the opportunity to examine the dynamics of sedimentary basins and their associated fluids to determine if past conditions were suitable for hydrocarbons to fill potential reservoirs and be preserved there. The success of any exploration campaign requires basin and petroleum system modeling as a methodology to predict the likelihood of success given available data and associated uncertainties. It is not guaranteed that hydrocarbons will be found by drilling a closed subsurface structure. Early petroleum system studies began more than 50 years ago. Geoscientists seek to describe how basins form, fill and deform, focusing mainly on compacting sediments and the resulting rock structures. Since then, tremendous efforts have been concentrated on developing methods to model these geological processes quantitatively. Studies such as applying mathematical algorithms to seismic, stratigraphic, palentologic, petrophysical data, and well logs were employed to reconstruct the evolution of sedimentary basins. In the early 1970s, geochemists developed methods to predict the petroleum generation potentials of source rocks in quantitative terms. After that, they began to use sedimentary basin models as geological frameworks for correlations between hydrocarbons and their potential source rocks. Since then, many concepts have been widely used in the petroleum industry, such as oil system, hydrocarbon system, hydrocarbon machine, and petroleum system. The term "petroleum system" is now commonly used in the industry. A petroleum system comprises a pod of active source rock and the oil and gas derived from it as established by geochemical correlation. The concept embodies all of the geologic elements and processes needed for oil and gas to accumulate. The essential elements include effective source rock, reservoir, seal and overburden rock. The processes include trap formation and the generation, migration and accumulation of petroleum. These elements and processes must occur in a proper order for the organic matter in a source rock to be converted into petroleum and then preserved. Absence of any of those elements can cause a dry prospect. In this dissertation, we use "basin and petroleum system modeling" (BPSM) as a method to track the evolution of a basin through geological time as it fills with sediments that could generate or contain hydrocarbons. We could also use it to evaluate and predict undiscovered conventional and unconventional hydrocarbon resources and to further understand the controls on petroleum generation, migration, accumulation. In deterministic forward modeling, basin and petroleum system processes are modeled from past to present using inferred starting conditions. Basin and petroleum system modeling is analogous to a reservoir simulation, but BPSM represents dynamic simulation through geological time. All of the dynamic processes in the basin and petroleum system modeling can be examined at several levels, and complexity typically increases with spatial dimensionality. The simplest is 1D modeling which examines burial history at a point location in a pseudowell. Two-dimensional modeling can be used to reconstruct oil and gas generation, migration and accumulation along a cross section. Three-dimensional modeling reconstructs petroleum systems at reservoir and basin scales and has the ability to display the output in 1D, 2D or 3D and through time. In general, which modeling approach is chosen depends on the purpose of the study and the types of problems to be resolved. Basin and petroleum system modeling continues to grow in importance as a tool to understand subsurface geology and basin evolution by integrating key aspects from geochemistry, geology, geophysics and stratigraphy. Among the above key aspects, geochemistry is the most important tool to understand the processes affecting petroleum systems. Better understanding of petroleum systems improves exploration efficiency. The first step in identifying petroleum systems is to characterize and map the geographic distribution of oil and gas types. Geochemical tools such as biomarkers, diamondoids and carbon isotope analysis are used to conduct oil-oil and oil-source correlation, which is key to understand and determine the geographic extent of petroleum systems in the basin. Chapter 1 offers a good example of how basin and petroleum system modeling and geochemistry improve understanding of active petroleum systems in the San Joaquin Basin, California. The modeling results indicate that there could be a deep, previously unrecognized source rock in the study area. Chapter 2 is a detailed unconventional geochemical analysis (i.e., diamondoid analysis, compound-specific isotopes of biomarkers and diamondoids) on petroleum systems in Arctic (Barents Sea and northern Timan Pechora Basin) to investigate deep sources in that area. Cutting-edge geochemical analyses were conducted in this project to identify the oil-oil and oil-source relationships and further understand reservoir filling histories and migration pathways. Since the deep source is at a great depth, thermal cracking always occurred in the source or the deeply buried reservoir, thus generating light hydrocarbons and gas. In addition, we hope to better understand the geochemical characteristics of worldwide Phanerozoic source rocks (Paleozoic source rock in Barents Sea-Timan Pechora area, Mesozoic and Cenozoic source rocks in the Vallecitos syncline in San Joaquin Basin). These results could also provide valuable input data for building basin and petroleum system models in the Arctic area once more data become available. Chapter 1 is a study of using basin modeling and geochemical analysis to evaluate the active source rocks in the Vallecitos syncline, San Joaquin Basin, and improve our understanding of burial history and the timing of hydrocarbon generation. Our earlier 1D modeling indicated that there could be two active source rocks in the syncline: Eocene Kreyenhagen and Cretaceous Moreno formations. The results differ from earlier interpretations that the Kreyenhagen Formation was the only source rock in the Vallecitos syncline, and suggest that the bottom of the Cretaceous Moreno Formation in the syncline reached thermal maturity as early as 42 Ma. The synclinal Eocene Kreyenhagen Formation became thermally mature as early as 19 Ma. Thick (~2 km) overburden rock in the central part of the syncline with additional heating from a thermal anomaly pushed the shallow Eocene Kreyenhagen source rock into the oil window in very recent times. In contrast, the Cretaceous Moreno source rock reached extremely high maturity (past the dry gas window). The 2D model results indicate that the bottom part of the Kreyenhagen Formation is in the mature stage of hydrocarbon generation and that the formation remains immature on the flanks of the present-day syncline. In contrast, the bottom part of the Moreno Formation achieved the gas generation zone and is in the oil generation zone on the flanks of the syncline. Biomarker analysis was conducted on 22 oil samples from the syncline. Source-related biomarkers show two genetic groups, which originated from two different source rocks. The 2D model results are supported by biomarker geochemistry and are also consistent with our earlier 1D burial history model in the Vallecitos syncline. In addition, we identified two potential petroleum systems in the Vallecitos syncline. The basin models for this study were conducted by me and Stephan Graham, Allegra Hosford Scheirer, Carolyn Lampe, Leslie Magoon. The detailed geological data was provided by Stephan Graham. The modeling related references and fundamental data were provided by Allegra Hosford Scheirer, but I conducted the modeling. The geochemical laboratory work and data analysis has been completed by me and supervised by Mike Moldowan and Kenneth Peters. The funding for this project was contributed by Basin and Petroleum System Modeling (BPSM) and molecular organic geochemistry industrial affiliates (MOGIA) programs. This chapter was submitted to Marine and Petroleum Geology with co-authors Stephan Graham, Allegra Hosford Scheirer and Kenneth Peters. All co-authors contributed important ideas, discussion, and guidance. Chapter 2 documents the existing deep source in the Barents Sea and northern Timan-Pechora Basin. Total thirty-four oil samples were analyzed to understand the types and distributions of effective source rocks and evaluate the geographic extent of the petroleum systems in the study area. Taxon-specific, age-related and source--related biomarkers and isotope data provided information on the depositional environment of the source rock, source input, and source age of the oil samples. A relationship between biomarker and diamondoid concentration was used to identify mixed oils having both oil-window and highly cracked components. Compound-specific isotope analyses of diamondoids and n-alkanes were used to deconvolute co-sourced oils and identify deep source rocks in the basin. The results suggest five major source rocks in the Barents Sea and the northern Timan-Pechora Basin: Upper Jurassic shale, Lower-Middle Jurassic shale, Triassic carbonate/shale, Devonian marl and Devonian carbonate. The Upper and Lower-Middle Jurassic source rocks are dominant in the Barents Sea. Triassic source rock consists of carbonate in the ons ...

This book was released on 2018-04-03 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the major changes induced by hydrocarbons (HCs) affecting rocks and surface sediments and their implications for non-seismic exploration methods, particularly for marine territories near Cuba. It examines the use of a digital elevation model (DEM) at 90x90m resolution for the detection of subtle, positive geomorphic anomalies related to hydrocarbon microseepage (vertical migration) on possible oil and gas targets. The results support the conclusion that the DEM data provides a low cost and fast offshore oil and gas preliminary exploration strategy. This data is useful serving to focus prospective areas with supplementary unconventional methods such as magnetic-induced polarization (MIP), useful to propose more expensive volumes for detailed 2D–3D seismic surveys.

Book excerpt: Basin Modelling: Practice and Progress aims to focus on the application of basin modelling tools to real problems, and to share experiences as to which techniques have worked and which have not. Modelling is a valuable process of risk reduction in exploration prospectivity assessment. It is an area which has significant room for risk reduction in new technologies, or in better practices with existing technologies. The impact of basin modelling on the exploration business is on risking source effectiveness, and by providing the timing framework for petroleum generation, migration and reservoir/trap formation. The reconstruction of the geological evolution of a sedimentary basin, and numerical quantification of this information is now considered to add considerable value. Insight into the development and understanding of a basin that develops during a basin modelling study provides as much value as the final numerical results.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Basin and Petroleum System Modeling (BPSM) is coupled-physics approach that tracks over the course of basin history, the evolution of basin geometry, compaction, pressure, fluid flow, temperature, and chemical transformation of organic matter to quantitatively predict petroleum generation, migration and accumulation. The measured data from petroleum wells, conversely, can help us improve our knowledge of the basin's geologic history. For basin modeling, the initial model building requires parameters that are derived from our geologic knowledge of various aspects of the basin history through time (typically tens to hundreds of millions of years), like stratigraphy, geochemistry, timing of tectonic events, and boundary conditions like heat flow. But because of the spatially and temporally changing depositional environments in a basin, it is very challenging to accurately know the large number of input parameters required to represent the basin history. In addition, current workflows of constraining the inputs to measured data or evidence often do not account for the various non-unique possibilities that can create the outcome that is the present. To address this challenge, we demonstrate the use of data from drilled wells and basin models in Bayesian networks to create a workflow that provides a quantitative way to: 1) Vary model parameters: consider all hypothesis without biasing to one, 2) Reduce uncertainty by calibrating the model to measured evidence without repeated manual adjustments 3) Update the understanding of model parameters when new data becomes available, without re-running computationally heavy coupled-physics simulations, by using Bayesian Networks and 4) Create traceable workflow with an integrated economic analysis to make optimal decisions under the reduced, but still present uncertainty using Influence Diagrams. An example of prolific petroleum producing Jeanne d'Arc basin, offshore Newfoundland, Canada, is used to illustrate how the workflow facilitates constraining the source rock quality, thermal history, and migration pathways. The thesis is comprised of three main chapters. They are written in journal format, each designed to be a standalone chapter: Chapter 1 presents a comprehensive basin study of the Jeanne d'Arc basin. This work examines the past five decades of research of the Mesozoic -- Cenozoic (250 million years ago to present) evolution of the basin. We closely examine the unknowns and uncertainties, and where some studies differ in their findings. We create a 3 -- dimensional numerical basin model spanning an area of about 3200 km2 and use the framework to incorporate large regional fault trends, spatial variation in the quality of organic matter, and to test the conceptual models of elevated basal heat flows associated with the rifting of North America from Africa, Iberia, and Greenland. The model can also help us understand the evolution of neighboring basins: Orphan and Flemish pass, which have a large resource potential. Chapter 2 presents the novel use of Bayesian Network approach to quantify the multi-dimensional uncertainty created from non-linear interactions of basin parameters and insufficient constraints. We show how the Bayes Net structure incorporates expert knowledge about cause-effect relationships like Total Organic Carbon (TOC) and quantity of hydrocarbons produced, as well as the conditional independence of temperature to the TOC. We elucidate with an example why this network representation can summarize the joint probabilities in a compact form. We then illustrate how the relationship between parameters is learnt from data produced by different realizations of the basin model, and how uncertainty in the input parameters is reduced by conditioning to measured evidence. With the 120 basin models created with varying input parameters, we show how this method helps quantitatively reduce uncertainty in both our understanding of geologic history and our predictions of drilled hydrocarbon fluid quantities. Sensitivity analysis shows that hydrocarbon accumulation is more sensitive to fault sealing properties than the basal heat flow in the range of present uncertainty. Our analysis finds that the time-varying permeability of faults largely impacts the leakage and filling of deep and shallow reservoirs, and hence their accumulation volumes. Chapter 3 illustrates a structured decision-making process that is informed by a quantitative evaluation of risks and returns from exploration decisions using influence diagrams. Once we learn the probabilities of different predictions of accumulation volumes from the methods developed in Chapter 2, a question arises: how do we use these probabilities to quantitatively inform decisions and actions? We compare influence diagrams to the more conventional decision trees and then use data from different times in the exploration history of the Jeanne d'Arc to demonstrate the use of influence diagrams to calculate the value of information and predict optimal survey, drilling, and production decisions. Finally, we argue that the graphical formulation is an excellent communication tool that can incorporate quantitative uncertainties, expert knowledge, and decision maker preferences for different types of decision scenarios. Our illustration with real data paves the path for incorporating this workflow in large organizational settings.

Available in PDF, EPUB and Kindle. Book excerpt: "Oil and gas discoveries in Australia's offshore basins are concentrated on the North West Shelf (Northern Carnarvon, Browse and Bonaparte basins) and Bass Strait (Gippsland, Otway and Bass basins). While discoveries have been made in a few regions outside these areas (e.g. Perth Basin), a large proportion of Australia's offshore basins remain exploration frontiers. However, the decline in oil production from the North West Shelf and Bass Strait basins since 2000 has led to an increasing exploration interest in the frontier basins. In order to improve our knowledge of the offshore frontiers and encourage exploration to these areas, from 2003-2011, Geoscience Australia was funded by the Australian Government to undertake a series of pre-competitive data acquisition and analyses programs in frontier basins around the Australian margin. This Record presents a comprehensive inventory of the geology, petroleum systems, exploration status and data coverage for 35 frontier basins, sub-basins and provinces, that draws on the results of those pre-competitive data programs, as well as exploration results and the geoscience literature. The Record also provides an assessment of the critical science and exploration questions and issues for each area. The results of each basin assessment are summarised in a prospectivity ranking. The availability of data and level of knowledge in each area is reflected in a confidence rating for that ranking. While the prospectivity of some areas is widely acknowledged to be high (e.g. Ceduna Sub-basin), the perception of prospectivity in many basins is negatively affected by the amount or quality of data available; in these basins, the acquisition of new data or targeted research could make a significant difference to the understanding of petroleum potential and likelihood of success. Therefore, recommendations for future work that could assist in addressing key knowledge or data gaps are included in each basin assessment." -- Online abstract.
