Analysis of Alternative Reservoir Development Plans to Improve Oil Recovery Based on Reservoir Simulation and Economic Evaluation

Abstract

Since the existing reservoir development plan applied only one well to produce the field depending on natural reservoir energy alone, this study focuses on well placement optimization and pressure maintenance techniques to improve oil recovery. In well placement optimization, addition of infill wells and new perforations are the main target. Reservoir pressure maintenance techniques applied in this study are limited to water injection, gas injection and simultaneous water and gas injection only. The study ends by calculating NPV of the base case and all the new simulated plans so as to determine the most profitable alternative plan to apply in Gulltop field.
