Poro-Mechanical Coupling for Flow Diagnostics

Abstract Accounting for poro-mechanical effects in full-field reservoir simulation studies and uncertainty quantification workflows using complex models is challenging, mainly because of the high computational cost. We hence introduce an alternative approach that couples hydrodynamics through existing flow diagnostics simulations with poro-mechanics to screen impact coupled processes on performance without significantly increasing overheads. In diagnostics, time-of-flight distributions influence regions can be used characterise field reservoir, which depends distribution petrophysical properties are altered due production-induced changes pore pressure effective stress. These extended calculations enable us quickly how dynamics reservoirs (e.g. connectivity, displacement efficiency, well allocation factors) affected by interactions between hydrodynamics. Our poro-mechanically informed account steady-state single-phase conditions based poro-elastic theory assume does not contain fractures. Fluid rock deformation sequentially. The equations discretised a finite-volume method two-point flux-approximation virtual element method, respectively. solution system considers stress-dependent permeabilities. Due nature proposed coupling strategy, these remain computationally efficient while providing first-order approximations interplay hydrodynamics, as we demonstrate series case studies. diagnostic provides complement traditional assess broader range uncertainties.
