Rock Physical Controls on Production-induced Compaction in the Groningen Field

Abstract Advancing production from the Groningen gas field to full depletion generates substantial, field-scale deformation, and surface subsidence. Quantifying associated risk requires understanding physical processes in the subsurface, in particular those related to deformation of the Permian sand...
