Sandstone

This book is exclusively devoted to a broad perspective of research interests centered around environmental geochemistry and the coupling of geology and geochemistry in sandstones. The main focus is to provide a well-balanced, up-to-date overview of all aspects related to geology, geochemistry and the understanding of ground-water systems, as geochemistry has contributed significantly to the understanding of ground-water systems. Water imbibition is fundamental to waterflood performance in low permeability reservoir rocks. Measuring the thermal properties of rocks and rock-fluid systems is difficult and time consuming and the results from such measurements are of limited value unless complete descriptions of the rock and fluids are given. The book also addresses an existing need for a method of predicting thermal behavior from other more easily measurable properties, cementation of sandstones and sources of silica during the diagenesis. Presented here are correlations developed for predicting the thermal conductivity of consolidated sandstones from the knowledge of density, porosity, permeability, and the formation resistivity factor.
