Final Report: Approaches to Some of the Outstanding Problems of Heterogeneous Compactive Deformation of Geomaterials

PDF Version Also Available for Download.

Description

Evidence from laboratory experiments and field observations on porous rocks (and other porous materials) has indicated that compaction does not necessarily occur homogeneously, but, instead, is localized in narrow planar zones that are perpendicular to the maximum compressive stress. Because the permeability of these zones is reduced by several orders of magnitude, they present barriers to fluid flow across them. Consequently, their formation in reservoirs or aquifers can adversely affect attempts to inject or withdraw fluids, such as CO2. Because the zones are narrow, they will be difficult to detect from the surface and, as a result, it is important ... continued below
