Numerical solution of non-isothermal flow in heavy oil reservoirs using parallel computing

Resumo

In this work, we have used the OpenACC to parallelize a reservoir simulator aiming to simulate two-
dimensional non-isothermal flows in a heavy oil reservoir. We have considered the production scenario with

a vertical well and two static heaters. We have also applied the Control Volume Finite Difference Method to
discretize flow and energy governing equations. We have chosen the Conjugate Gradient Method to solve the
systems of algebraic equations to obtain pressure and temperature fields along with an operator splitting method. In
the study of computational performance, we have employed different computational meshes and achieved speedup
values greater than eight.
