Indonesia’s rapidly increasing demand for crude oil has surpassed 1.6 million barrels per day (MBOPD). Recognizing this urgent demand, the Indonesian government, through the Ministry of Energy and Mineral Resources, has set an ambitious target to produce 1 MBOPD by 2030. An innovative and efficient approach is required to achieve this target, with field development being a key strategic focus. This field development aims to maximize hydrocarbon production effectively and economically. This study focuses on developing the field at the primary recovery stage by comparing analytical and simulation calculations. The analysis is conducted on a static model of field "Z," which has 23.43 MMSTB of oil in place and 9 active wells. The analytical method calculates the Estimated Ultimate Recovery (EUR), drainage radius, and Recovery Factor (RF) for the existing wells and determines the number of wells that can be infilled. These results are then compared with simulation outcomes. The 3D dynamic simulation method uses Simulation Opportunity Index (SOI) and Movable Oil in Place (MOIP) maps to identify the locations of infill wells. The projection spans 20 years, from 2023 to 2043. The number of wells needed is determined using creaming curve analysis, which is discussed in the study.
