Abstract

In the current study, a new simulator is designed to manipulate what is known as hybrid grid global system for oil reservoir simulation. The global system composed of two subsystems, one covering the regions around the well which is called radial (r-e) model while the second is linear (x-y) which covers the rest of reservoir regions. The constructed simulator is able to deal linear and radial two phase flow compressible oil water with the consideration of the rock compressibility. The two subsystems are solved simultaneously within the global system of the reservoir. The outer and inner boundary conditions between the two systems are treated and improved interactively during each time step depending on the relative positions of the two subsystems in reservoir. The method of formulation and system solving also are introduced with the main characteristics of the new simulator.
