A block preconditioner for non-isothermal flow in porous media

Abstract:

In petroleum reservoir simulation, the industry standard preconditioner, the Constrained Pressure Residual method (CPR), is a two-stage process which involves solving a restricted pressure system with Algebraic Multigrid (AMG). Initially designed for isothermal models, this approach is often used in the thermal case. However, it does not have a specific treatment of the additional energy conservation equation and temperature variable. We seek to develop preconditioners which better capture th...
