Field Development Analysis Based on Analytical Approach in Order to Improve Simulation Reservoir Performance Prediction

Reservoir simulation represents powerful tool for future prediction of reservoir performance. However it is exposed to subjectivity of reservoir engineer. Therefore, analytical approach is used to reduce subjective influence of interpreter and improve future reservoir performance prediction accuracy. Material Balance is used in order to reduce uncertainties prior to simulation modeling. Initially connected hydrocarbon volumes (STOIIP) was determined. This was followed by determination of possible reservoir compartmentalization and determination of hydrocarbon contact. Since adequate Material Balance model was determined, estimation of reservoir drive mechanisms through analysis of reservoir pressure and fluid production was performed. Further, more efficient history matching procedure was conducted. Eventually, future performance prediction using analytical approach was performed. Finally, results obtained using Material Balance analysis were used for more accurate simulation and performance prediction. These results were compared and studied in order to provide recommendations for field development optimization.
