Abstract
Kaji Semoga (KS) field has produced primarily from Baturaja Formation, which is a limestone formation 2,600-2,700 ft TVD. In early 2001, when the reservoir pressure was decreasing and the wells ceased to flow, gas lift was installed and became the main artificial lift in KS. But due to the decline in gas production, and to reduce the decline, an artificial lift implementation project was conducted in 2007. The objective of the project was to convert some gas lift wells to ESP wells. As a result of implementing these projects, ESP will be the dominant artificial lift for production wells in KS, contributing to approximately 70% of total oil production
