Abstract

This paper addresses the class of tarmat reservoir subject to bottom water drive. Different shapes of broken tar layers are assumed after the tarmat breaks down. These shapes were simulated by a three dimensional glass bead physical model to study experimentally the behavior of water-oil ratio and oil recovery. The experimental results were then simulated numerically by a three phase, three dimensional model. Five different cases of barriers were studied: A square and disk beneath the well, a hollow square and disk beneath the well and a half plane. The results showed that breakthrough time occurs earlier in the case where the tarmat barrier has a hole underneath the well while it is delayed considerably in the case of tarmat barrier shaped in the form of a disk beneath the well.
