Zimmerman R.W. Compressibility of Sandstones

Amsterdam - Oxford - New York - Tokyo 1991. Elsevier, 183 pages.This book presents a comprehensive treatment of the elastic volumetric response of sandstones to variations in stress. The theory and data presented apply to the deformations that occur, for example, due to withdrawal of fluid from a reservoir, or due to the redistribution of stresses caused by the drilling of a borehole. Deformations that occur over geologic time scales are in general excluded, since such processes involve chemical and thermal effects in addition to purely mechanical deformation. Note that while the data presented to illustrate the principles discussed in the book are exclusively for consolidated sandstones, most of the theoretical relationships, bounds, etc. that are discussed are applicable to all rock-fluid systems.Part one: Compressibility and stress
