Sandstone Petroleum Reservoirs presents an integrated, multidisciplinary approach to the geology of sandstone oil and gas reservoirs. Twenty-two case studies involving a variety of depositional settings, tectonic provinces, and burial/diagenetic histories emphasize depositional controls on reservoir architecture, petrophysical properties, and production performance. An introductory section provides perspective to the nature of reservoir characterization and highlights the important questions that future studies need to address. A "reservoir summary" following each case study aids the reader in gaining quick access to the main characteristics of each reservoir. This casebook is heavily illustrated, and most data have not been previously published. The intended audience comprises a broad range of practicing earth scientists, including petroleum geologists, geophysicists, and engineers. Readers will value the integration of geological versus engineering interests provided here, and will be enabled to improve exploration and production results.

Sequence stratigraphy is a powerful tool for the prediction ofdepositional porosity and permeability, but does not account forthe impact of diagenesis on these reservoir parameters. Therefore,integrating diagenesis and sequence stratigraphy can provide abetter way of predicting reservoir quality. This special publication consists of 19 papers (reviews and casestudies) exploring different aspects of the integration ofdiagenesis and sequence stratigraphy in carbonate, siliciclastic,and mixed carbonate-siliciclastic successions from variousgeological settings. This book will be of interest tosedimentary petrologists aiming to understand the distribution ofdiagenesis in siliciclastic and carbonate successions, to sequencestratigraphers who can use diagenetic features to recognize andverify interpreted key stratigraphic surfaces, and to petroleumgeologists who wish to develop more realistic conceptualmodels for the spatial and temporal distribution of reservoirquality. This book is part of the ahref="http://www.sedimentologists.org/"International Associationof Sedimentologists/a (IAS) Special Publications.

The 3D geological model is still regarded as one of the newest and most innovative tools for reservoir management purposes. The computer modelling of structures, rock properties and fluid flow in hydrocarbon reservoirs has evolved from a specialist activity to part of the standard desktop toolkit. The application of these techniques has allowed all disciplines of the subsurface team to collaborate in a common workspace. In today's asset teams, the role of the geological model in hydrocarbon development planning is key and will be for some time ahead. The challenges that face the geologists and engineers will be to provide more seamless interaction between static and dynamic models. This interaction requires the development of conventional and unconventional modelling algorithms and methodologies in order to provide more risk-assessed scenarios, thus enabling geologists and engineers to better understand and capture inherent uncertainties at each aspect of the geological model's life.

Clay minerals are one of the most important groups of minerals thatdestroy permeability in sandstones. However, they also react withdrilling and completion fluids and induce fines migration duringhydrocarbon production. They are a very complex family of mineralsthat are routinely intergrown with each other, contain a wide rangeof solid solutions and form by a variety of processes under a widerange temperatures and rock and fluid compositions. In this volume, clay minerals in sandstones are reviewed interms of their mineralogy and general occurrence, their stable andradiogenic isotope geochemistry, XRD quantification, their effectson the petrophysical properties of sandstones and theirrelationships to sequence stratigraphy and palaeoclimate. Thecontrols on various clay minerals are addressed and a variety ofgeochemical issues, including the importance of mass flux, links tocarbonate mineral diagenesis and linked clay mineral diagenesis ininterbedded mudstone-sandstone are explored. A number of casestudies are included for kaolin, illite and chlorite cements, andthe occurrence of smectite in sandstone is reviewed. Experimentalrate data for clay cements in sandstones are reviewed and there aretwo model-based case studies that address the rates of growth ofkaolinite and illite. The readership of this volume will include sedimentologists andpetrographers who deal with the occurrence, spatial and temporaldistribution patterns and importance of clay mineral cements insandstones, geochemists involved in unraveling the factors thatcontrol clay mineral cement formation in sandstones and petroleumgeoscientists involved in predicting clay mineral distribution insandstones. The book will also be of interest to geologistsinvolved in palaeoclimate studies basin analysis.

Quartz is the major porosity-reducing cement in many sandstonesequences. Therefore, Quartz cements represent a key source ofpetrographic and geochemical information about diagenetic history.They are also the major determinant of sandstone reservoirquality. While the ultimate goal of research in this area is to makerobust predictions about the amount and distribution of quartzcements in a wide variety of depositional and burial settings,there are nevertheless large areas of the subject that are poorlyunderstood and remain the subject of controversy. The aim of this Volume, which is based partly on paperssubmitted to a 1996 workshop in Belfast, and partly on invitedcontributions, is to bring together some of the main strands ofresearch into quartz cements and provide a focus for debate anddirection for future research. This book will be welcomed by sedimentologists, petrographersand geochemists involved in sandstone digenesis, as well as bypetroleum geologists seeking a deeper understanding of the factorsinfluencing reservoir porosity and permeability. Contributors from 11 countries and 4 continents. Represents the benchmark in quartz cement research.

This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs. Promotes pragmatic interpretation of deep-water sands using alternative possibilities Validates the economic importance of SMTDs and BCRS in deep-water exploration and production Rich in empirical data and timely new perspectives

This conference was arranged by the Norwegian Petroleum Society in order to commemorate the first 25 years of exploration on the Norwegian Continental Shelf. Sixty papers and posters were presented of which 25 have been selected for this volume. Since the start of exploration activities during the mid 1960's the North Sea has not only proved to be one of the main petroleum provinces in the world, but has also established itself as an excellent laboratory for geoscientific research and application. This development has been stimulated greatly by the openess towards exchange of technical data encouragement by the Norwegian authorities. The objective of this book is to assess the results of 25 years of exploration in Norway. It focuses on lessons learned from past experiences as well as considering future challenges facing geoscientists in the industry (relating to both exploration and exploitation activities). Included, are papers which assess the status and future trends of exploration in the main geological provinces on the Norwegian Continental Shelf from the Central Graben in the south to Svalbard and the Russian Artic in the north.

Over the past 20 years there has been a major growth in efforts to quantify the geometry and dimensions of sediment bodies from analogues to provide quantitative input to geological models. The aim of this volume is to examine the current state of the art, from both an industry and an academic perspective. Contributions discuss the challenges of extracting relevant data from different types of sedimentary analogue (outcrop, process models, seismic) and the application and significance of such information for improving predictions from subsurface static and dynamic models. Special attention is given to modelling reservoir properties and gridding issues for predicting subsurface fluid flow. As such, the volume is expected to be of interest to both the geoscience community concerned with the fundamentals of sedimentary architecture as well as geological modellers and engineers interested in how these characteristics are modelled and influence subsurface predictions.

The Norwegian Continental Shelf (NCS), focus of this special publication, is a prolific hydrocarbon region and both exploration and production activity remains high to this day with a positive production outlook. A key element today and in the future is to couple technological developments to improving our understanding of specific geological situations. The theme of the publication reflects the immense efforts made by all industry operators and their academic partners on the NCS to understand in detail the structural setting, sedimentology and stratigraphy of the hydrocarbon bearing units and their source and seal. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings. Special attention is given to the integration of both analogue studies and process-based models with the insights gained from extensive subsurface datasets.

Carbonate cements are very common and abundant in clastic sequences. They profoundly influence the quality of hydrocarbon reservoirs and supply important information on palaeoenvironments and the chemical composition and flow patterns of fluids in sedimentary basins. Despite this importance, their distribution patterns in time and space and their geochemical evolution are not yet deeply explored and elucidated. This Special Publication contains 21 review papers and case studies on carbonate cementation in clastic sequences written by invited specialists on the subject. These papers present a wide and deep coverage that enhance our knowledge about carbonate cementation in various clastic depositional environments, tectonic settings and burial histories. The book will be of special interest to researchers, petroleum geologists and teachers and students at the postgraduate level.
