Quantitative Diagenesis Recent Developments And Applications To Reservoir Geology

Reservoirs generally consist of sandstones or carbonates exhibiting heterogeneities caused by a wide range of factors. Some of these formed depositionally (e.g. as channels, palaeosols, clay seams or salts), others may be diagenetic in origin (e.g. carbonate or silica cemented zones, authigenic clays, karstic surfaces). The severity with which diagenesis affects rock systems results from the interplay between the diagenetic process itself and the timescale over which it operated. The book provides a wide-ranging overview of diagenetic processes and responses in calcareous, argillaceous, arenaceous and carbon-rich (microbial and organic) sedimentary systems. It introduces diagenetic concepts, reviews existing knowledge, and shows how existing qualitative approaches might be developed in more quantitative ways. Several chapters consider mass balance calculations and the temporal and spatial aspects of diagenetic processes. It is unique, as a textbook, in providing such a breadth of diagenetic subject range and such depth of coverage in each topic. It provides a source reference for advanced students and professionals active in reservoir and aquifer studies.

This book honors the career of Professor Elizabeth Gierlowski-Kordesch who was a pioneer and leader in the field of limnogeology since the 1980s. Her work was instrumental in guiding students and professionals in the field until her untimely death in 2016. This collection of chapters was written by her colleagues and students and recognize the important role that Professor Gierlowski-Kordesch had in advancing the field of limnogeology. The chapters show the breadth of her reach as these have been contributed from virtually every continent. This book will be a primary reference for scientists, professionals and graduate students who are interested in the latest advances in limnogeologic processes and basin descriptions in North and South America, Europe, Africa, and China. *Free supplementary material available online for chapters 3,11,12 and 13.

This book represents the proceedings of the 9th written by a very active group of physicists at Kongsberg seminar, held at the Norwegian Mining the University of Oslo - physicists interested in Museum located in the city of Kongsberg about complex systems in general and geo-like systems 70 km Southwest of Oslo. The Kongsberg district in particular. is known for numerous Permian vein deposits of The content of the book is organized into three native silver, and mining activity in the area lasted major parts following the introductory chapter. for more than 300 years, finally ceasing in 1957. Chapters 2 to 7 primarily treat the role of fluids The previous eight Kongsberg seminars were in specific geological environments, ranging from focused on ore-forming processes and all of these sedimentary basins (Chapters 2-3) to contact were organized by Professor Arne Bj0rlykke, now metamorphic/hydrothermal scenarios (Chapters director of the Norwegian Geological Survey. 4-5) and regional metamorphic settings (Chapters Since process-orientated research tends to break 6-7). The following four chapters (8-11) focus down the traditional barriers between the different on various properties of fluid-rock systems that geological disciplines, this seminar has always are critical in controlling flow and transport been a meeting point for people with a variety through rocks. These include: mineral solubility of geological backgrounds.

This textbook outlines the physical, chemical, and biologic properties of the major sedimentary rocks, as revealed by petrographic microscopy, geochemical techniques, and field study. It covers the mineralogy, chemistry, textures, and sedimentary structures that characterise sedimentary rocks, and relates these features to the depositional origin of the rocks and their subsequent alteration by diagenetic processes during burial. In addition to detailed sections on siliciclastic and carbonate rocks, it also discusses evaporites, cherts, iron-rich sedimentary rocks, phosphorites, and carbonaceous sedimentary rocks such as oil shales. This second edition maintains the comprehensive treatment of sedimentary petrography and petrology provided in the first edition, and has been updated with new concepts and cutting-edge techniques like cathodoluminescence imaging of sedimentary rocks and backscattered electron microscopy. It is ideal for advanced undergraduate and graduate courses in sedimentary petrology, and is a key reference for researchers and professional petroleum geoscientists.

Sequence stratigraphy is a powerful tool for the prediction of depositional porosity and permeability, but does not account for the impact of diagenesis on these reservoir parameters. Therefore, integrating diagenesis and sequence stratigraphy can provide a better way of predicting reservoir quality. This special publication consists of 19 papers (reviews and case studies) exploring different aspects of the integration of diagenesis and sequence stratigraphy in carbonate, siliciclastic, and mixed carbonate-siliciclastic successions from various geological settings. This book will be of interest to sedimentary petrologists aiming to understand the distribution of diagenesis in siliciclastic and carbonate successions, to sequence stratigraphers who can use diagenetic features to recognize and verify interpreted key stratigraphic surfaces, and to petroleum geologists who wish to develop more realistic conceptual models for the spatial and temporal distribution of reservoir quality. This book is part of the International Association of Sedimentologists (IAS) Special Publications. The Special Publications from the IAS are a set of thematic volumes edited by specialists on subjects of central interest to sedimentologists. Papers are reviewed and printed to the same high standards as those published in the journal Sedimentology and several of these volumes have become standard works of reference.

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.

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.
