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.

Linking Diagenesis to Sequence Stratigraphy (Special Publication 45 of the IAS)

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.

Carbonate Cementation in Sandstones

Quartz is the major porosity-reducing cement in many sandstone sequences. Therefore, Quartz cements represent a key source of petrographic and geochemical information about diagenetic history. They are also the major determinant of sandstone reservoir quality. While the ultimate goal of research in this area is to make robust predictions about the amount and distribution of quartz cements in a wide variety of depositional and burial settings, there are nevertheless large areas of the subject that are poorly understood and remain the subject of controversy. The aim of this Volume, which is based partly on papers submitted to a 1996 workshop in Belfast, and partly on invited contributions, is to bring together some of the main strands of research into quartz cements and provide a focus for debate and direction for future research. This book will be welcomed by sedimentologists, petrographers and geochemists involved in sandstone digenesis, as well as by petroleum geologists seeking a deeper understanding of the factors influencing reservoir porosity and permeability. Contributors from 11 countries and 4 continents. Represents the benchmark in quartz cement research.

Quartz Cementation in Sandstones (Special Publication 29 of the IAS)

Clay minerals are one of the most important groups of minerals that destroy permeability in sandstones. However, they also react with drilling and completion fluids and induce fines migration during hydrocarbon production. They are a very complex family of minerals that are routinely intergrown with each other, contain a wide range of solid solutions and form by a variety of processes under a wide range temperatures and rock and fluid compositions. In this volume, clay minerals in sandstones are reviewed in terms of their mineralogy and general occurrence, their stable and radiogenic isotope geochemistry, XRD quantification, their effects on the petrophysical properties of sandstones and their relationships to sequence stratigraphy and palaeoclimate. The controls on various clay minerals are addressed and a variety of geochemical issues, including the importance of mass flux, links to carbonate mineral diagenesis and linked clay mineral diagenesis in interbedded mudstone-sandstone are explored. A number of case studies are included for kaolin, illite and chlorite cements, and the occurrence of smectite in sandstone is reviewed. Experimental rate data for clay cements in sandstones are reviewed and there are two model-based case studies that address the rates of growth of kaolinite and illite. The readership of this volume will include sedimentologists and petrographers who deal with the occurrence, spatial and temporal distribution patterns and importance of clay mineral cements in sandstones, geochemists involved in unraveling the factors that control clay mineral cement formation in sandstones and petroleum geoscientists involved in predicting clay mineral distribution in sandstones. The book will also be of interest to geologists involved in palaeoclimate studies basin analysis. Latest geochemical data on clays in sandstones Provides important information for geologists involved in basin analysis, sandstone petrology and petroleum geology If you are a member of the International Association of Sedimentologists (IAS), for purchasing details, please see: http://www.iasnet.org/publications/details.asp?code=SP34
