Geomechanical Modeling of Reservoir Compaction, Surface Subsidence, And Casing Damage at the Belridge Diatomite Field

摘要

Geologic, and historical well failure, production, and injection data were analyzed to guide development of three-dimensional geomechanical models of the Belridge diatomite field, California. The central premise of the numerical simulations is that spatial Gradients in pore pressure induced by production and injection in A low permeability reservoir may perturb the local stresses and Cause subsurface deformation sufficient to result in well failure.
