Abstract
Currently, Indonesia is experiencing various changes and improvements to the regulations for the work contract system, which is in line with the activities carried out in the oil and gas industry. Things like this will certainly have an impact on investment in the upstream oil and gas sector. The decrease in production rate is one of the main problems in oil and gas production which is caused by the damage to the production well formation, to increase it again, namely using the matrix acidizing workover method by injecting solvent. Seeing the unfavorable condition of oil and gas and high cost recovery, and the results obtained were not comparable to that of the contractor, so there was a change in the new contract system by adding the number of splits for the contractor to be considered in managing the fiel. The PSC Gross Split Scheme is the newest oil and gas contract scheme which is the first to be implemented in Indonesia and in the world, which was released by the Minister of Energy and Mineral Resources (ESDM). In contrast to the PSC Cost Recovery contract scheme, the split between the government and the contractor in the PSC gross split is set at the beginning and then the gross revenue is directly divided between the two according to the criteria for variable and progressive factors, which of course the contractor split will be bigger than the Government. However, the government gets revenue from the tax and the split results. In this study, we compared two wells using the PSC Cost Recovery and PSC Gross Split schemes with an investment of US $ 542,100 wells Alfa and US $ 554,569 wells at average oil price US $ 85.75 oil prices, so that the NPV results of Alfa wells using the PSC Cost Recovery scheme were US$ 2.447.340,06 and an IRR of 256.35%, for the GS scheme US $ 4.745.286,13 with an IRR of 482.01%. For the Beta well, the PSC Cost Recovery scheme received an NPV of 2.573.225,31 US $ and an IRR of 267.57%, the GS scheme received an NPV of 5.005.787,81US $ with an IRR of 527.63%. From the results of the PSC Gross Split economic indicators, it shows results that are more profitable and attractive to contractors when applied to the oil and gas field. The sensitivity analysis was performed by reducing or adding up by 15% to 85% and 115%. From the results of the analysis carried out, the oil price and cumulative production are the parameters that most influence the results of the NPV, IRR, POT, PI and other economic indicators.
