A Computer Program for Excess Water Production Diagnosis Case Study– Heglig Oil Field – Sudan

Abstract

Heglig oil field is suffer from massive water production which is not only negatively affects the oil production rate, but also entails costly and time-consuming water management operationsin order to be able to tackle the excess water production problem effectively, it is vital to identify the source of the problem first. and therefore accurate methodology required to diagnose and evaluate water production mechanisms. In this work, a new developed program was presented for quickly diagnose of water production mechanisms, using Chan’sconning and channeling differentiation mechanism. Different 5 wells were studied using the generated program; through which 3 wells were presented water channeling behavior while one well was presented water conning and the last well appear to be water/oil contact rising through its plot.
