Modeling of Reservoir Compaction and Surface Subsidence at South Belridge

Abstract

Summary Finite-element models of depletion-induced reservoir compaction and surface subsidence have been calibrated with observed subsidence, locations of surface fissures, and regions of subsurface casing damage at South Belridge and used predictively for the evaluation of alternative reservoir-development plans. Pressure maintenance through diatomite waterflooding appears to be a beneficial means of minimizing additional subsidence and Assuring as well as reducing axial-compressive-type casing damage.
