The Integration of Rate Transient Analysis in Dynamic Material Balance Simulation to Predict Reservoir Performance in an Oil Field
Authors: ,
Abstract: Estimation of hydrocarbon in place and remaining reserves as well as being able to predict future reservoir performance for oil and gas reservoirs is extremely needed from time when such reservoirs are first discovered to future times when they are being developed. To achieve this purpose, Dynamic material balance simulation is one of good solution as this method is an advanced application of material balance method as well as integrated to production and system performance analysis. However, a lack of information or data in particularly reservoir characteristics is mainly become one of issue in performing production and system performance analysis. Consequently, it will affect the results will be not valid. Integration of rate transient analysis in dynamic material balance simulation could be an alternative solution in dealing with this issue. In this paper, the integration method is applied in an onshore oil field which is “X†Field. Material balance method is used in evaluating reservoir pressure and drive mechanism analysis. Type curve methods as application of rate transient analysis are performed to estimate reservoir characteristics which are permeability and skin factor. These results are used to support in modeling and obtaining production performance of the wells. Afterwards, integrated of these methods are performed in conducting dynamic material balance simulation for estimating remaining reserves and forecasting future reservoir performance. In summary, Reservoir drive mechanism in “X†Field is strong water drive mechanism as depletion of reservoir pressure is relatively low as well as currently it is still above the bubble point pressure and there is support from aquifer influx. The remaining reserves in “X†Field at end of prediction is around 705.80 MSTB based on existing artificial lift production method.
