Improved solution of displacements due to a compacting reservoir over a rigid basement

Abstract

Geertsma's analytical method is often used to compute strain and stress changes around a compacting geological reservoir. The present work extends Geertsma's solution by adding a rigid layer beneath the compacting reservoir. Analytical formulae are presented for all the components of displacement of a point in the subsurface. Our derivation includes the correction of an error found in the paper written by Sharma in 1956. © 2010 Elsevier Inc.
