Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM).

It is proven to be able to provide a computationally efficient means of handling single and multiphase flow in a homogeneous medium through the comparison study with Comsol. The accuracy can be further enhanced by incorporating singularity programming and Laplace Transformation (LT) techniques; hence an alleviation of numerical errors caused by singularities and a time derivative is achieved.

It is observed that this method can be an alternative tool to analyze pressure transient performance in a single phase flow through which the important reservoir parameters can be estimated effectively; and study saturation profile and interface behavior for an immiscible flow which plays a key role in enhanced oil recovery processes.
