Numerical Investigation on Geomechanical Response and Well Performance in Shale Condensate Gas Reservoirs

Compared with conventional reservoirs, shale gas flow is greatly affected by matrix/fracture deformation, as well nonlinear coupled transport mechanisms. In this paper, a hydro-mechanical model presented to describe the fluid in deformable formation. A unified compositional developed for modeling of multiphase phase transition. series mechanisms, including Knudsen diffusion, multi-component adsorption, confined behavior and molecular are considered accurate description reservoirs. Matrix deformation based on linear poroelasticity theory. The fractures complex geometry modeled embedded discrete fracture (EDFM). mechanical responses handled different constitutive models, which implemented into model. geomechanical models spatially discretized using finite volume method (FVM) element (FEM), sequentially iterative approach applied solving Then impacts orientation, in-situ stress condition, bottom hole pressure production investigated through sensitivity analysis. With multiple mechanisms dynamic incorporated, response performance condensate reservoirs can be accurately captured.
