Abstract

Many reservoirs that experienced a decline in production pushed oil and gas companies to increase oil production and the technology used again. Enhanced Oil Recovery is a solution to the problem of a reservoir that has decreased production. One part of EOR technology is polymer gel. Gel polymer injection is one method that has been widely applied in the world oil field. The success shown by the polymer gel method is to increase oil recovery. The polymer gel method is a fairly economical method compared to other methods, to prove the economics of polymer injection it is necessary to calculate and analyze economic indicators such as net present value (NPV), Internal rate of return (IRR) and Pay Out Time (POT) . The purpose of this study was conducted to determine the economics of the polymer gel project to be carried out, so that the results of calculations can be concluded the feasibility of the polymer gel injection project. The contract used in this study is Gross Split. Based on the addition of the base split for contractors by 43%, the variable and progressive split obtained by the contractor division by 71%. The next stage by calculating the economic indicators of polymer gel injection with an investment of 2984 US $ M and an oil price of 61.96 US $ / bbl obtained from the calculation of the NPV value @ 10% = 4,970.89 US$M, IRR = 168%, POT = 0.4 years, PI = 2.67. The sensitivity analysis was carried out on this project by changing the assumptions to 85% and 115%. The results obtained indicate that the price of oil is a parameter that affects the value of the NPV followed by oil production, opex and investment. The critical point of oil prices occurs when oil prices are reduced to 62% of the project's initial price. Likewise, oil production experienced a critical point when production decreased by 49% of the total initial production of the project. Based on the results of the calculation of profit indicators and sensitivity analysis above it can be concluded that the polymer gel injection project is feasible because all indicators meet the eligibility requirements of a project.
