Offshore oil wells frequently encounter production challenges such as reservoir pressure depletion and high water cut, limiting natural flow to the surface. To address this, Sumur X in Lapangan Y has been utilizing a gas lift system since 2006. While effective in maintaining production, the system demands high gas consumption, particularly in deep wells with high water cut. This study proposes a dual artificial lift configuration by combining a jet pump at the lower section and a gas lift at the upper section of the well. Using nodal analysis in commercial software, four scenarios were simulated: natural flow, single gas lift, single jet pump, and dual artificial lift. The results indicate that the dual system successfully lifted fluids to the surface and reduced the gas injection rate by 45.5% compared to the single gas lift system. This demonstrates the potential of dual artificial lift to optimize production and improve operational efficiency, making it a promising solution for offshore wells with complex production challenges.
