“…Third, the effects of time‐dependent deformation processes, such as subcritical crack growth, or rate‐dependent grain boundary friction have been largely neglected, leaving the rate dependence of the stress‐strain and yield behavior of sands and sandstones quantified to only a limited extent (Brantut et al, , ; Brzesowsky, Hangx, et al, ; De Waal, ; Heap et al, , ; Karner et al, ). Indeed, in many treatments of pressure depletion during oil, gas, or geothermal energy production from sandstone reservoirs, inelastic deformation is neglected completely and reservoir compaction is, in first approximation, assumed to be characterized by a simple, elastic compaction coefficient (Altmann et al, ; Geertsma, ; Lele et al, ; Mulders, ; van Eijs et al, ; Wassing et al, ; Zoback, ).…”
