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.

Product Description: Computer Climate Models are essential tools for understanding environmental change but the results of modelling exercises are seldom accessible to the wider community of teachers and researchers on their desktop machines. This CD ROM presents the results of a series of simulations of global climate for the Carboniferous (300Ma) through the Mesozoic (150, 95 and 70Ma), Tertiary (55 and 15Ma) and Quaternary (115, 21 and 6 Ka) to Present Day and enhanced greenhouse effect simulations (2 x CO2) for surface temperature, soil moisture, precipitation, cloud cover, surface pressure, wind strengths, storminess, and snow depth in up to three projection modes: Rectilinear, Mollweide and Polar...read more
