COMPARISON FOR OIL RECOVERY BETWEEN WATER AND POLYMER FLOODING IN THE U-THONG OIL FIELD
Keywords:
U-Thong oil field, water flooding, polymer flooding, reservoir simulationAbstract
The objective of this research is to compare water and polymer flooding case studies by using a reservoir simulation to simulate the improvement of oil recovery in the reservoir of the U-Thong oil field and to study the economics of both methods to find the best case scenario. The physical properties of the reservoir rock and fluids, porosity, permeability, and reservoir pressure were collected from a literature review and theoretical assumptions. The reserve size of the reservoir is around 6.48 million barrels injected with a direct drive pattern (2 production wells and 2 injection wells) in the 1st year. Results of this research revealed that polymer flooding is the best method./, as the summary of the oil recovery factor and net present value result is 55.03% and 35.53 MMUS$, respectively (more than water flooding at 5.57% and 2.52 MMUS$, respectively).
