A critical review on coupled geomechanics and fluid flow in naturally fractured reservoirs

Naturally fractured reservoirs have been a source of challenging issues with regard to field development, well stability, drilling, and enhanced oil recovery, as connected fracture system can totally dominate the flow patterns. Because high degree heterogeneity in characteristics reservoir geomechanics, several mathematical, numerical discretization methods are proposed predict hydrodynamics behaviour naturally reservoirs. This paper presents critical review terms geomechanics fluid flow. In case poorly fractures high-density networks, compared characteristic length interest, multi-continuum approaches widely applicable. The dual continuum approach handle matrix interaction implicitly much more conveniently than Discrete Fracture Network (DFN) Matrix (DFM) approaches, but it cannot capture geometry explicitly where is main path area interest. Distinct mathematical modelling also addressed this paper. context, various coupling schemes discussed. Recent research challenges related multiphase flow, schemes, reviewed. It concluded that despite efforts, coupled still issue models hydrodynamic behaviour, such deformation at adopting best very dependent on desired hydro-mechanical aspects be investigated. • Modelling Fluid Flow Transport Fractured Porous Media.
