Book Description
This book discusses how sediments compact with depth and applications of the compaction trends. Porosity reduction in sediment conveniently indicates the degree of sediments compacted after deposition. Published empirical curves- the compaction curves- are depth-wise porosity variation through which change in pore spaces from sediment surface to deeper depths e.g. up to 6 km can be delineated. Porosity is derived from well logs. Compaction curves, referred to as the Normal Porosity Profile of shales, sandstones and shale bearing sandstones of different models are reviewed along with the different mechanical and chemical compaction processes. These compaction models reveals how porosity reduces depth-wise and the probable reason for anomalous zones. Deviation from these normal compaction trends may indicate abnormal pressure scenarios: either over- or under pressure. We highlight global examples of abnormal pressure scenarios along with the different primary- and secondary mechanisms. Well logs and cores being the direct measurements of porosity, well log is the only cost-effective way to determine porosity of subsurface rocks. Certain well logs can detect overpressure and the preference of one log above the other helps reduce the uncertainty. Apart from delineation of under-compacted zones by comparing the modeled- with the actual compaction, porosity data can also estimate erosion.

Book Description
Plan of Review This review of clay microstructure is aimed at the diverse group of professionals who share an interest in the properties of fine-grained minerals in sediments. During the last several decades, members of this group have included geologists, soil scientists, soil engineers, engineering geologists, and ceramics scientists. More recently, it has included significant numbers of marine geologists and other engineers. Each of the disciplines has developed special techniques for investigating properties of clay sediments that have proven to be fruitful in answering questions of central interest. Knowledge of clay microstructure-the fabric of a sediment and the physico chemical interactions between its components-is fundamental to all these disciplines (Mitchell 1956; Lambe 1958a; Foster and De 1971). Clay fabric refers to the spatial distribution, orientations, and particle-to-particle relations of the solid particles (generally those less than 3. 9 /Lm in size) of sediment. Physico-chemical interac tions are expressions of the forces between the particles. In this review, we trace the historical development of under standing clay microstructure by discussing key scientific papers published before 1986 on physico-chemical interactions in fine grained sediments and on clay fabric. Since the development follows an intricate path, the current view of clay microstructure is summarized. This summary includes a discussion of the present state of knowledge, the observations made so far, and the facts that are now established.
