This monograph presents a wide range of examples showing the different patterns of behavior in permeable aquifers and highlights the interactions between the various elements involved. The author provides a comprehensive investigation of the effects of geometry, permeability, and fluid flow dynamical properties on the ability of an aquifer to retain oil and gas accumulations. With its highly accessible format, each chapter allows for a quick survey of specific factors in the development of hydrocarbon behavior using illustrations. Chapters also feature case histories and examples.
