Abstract
Oil and Gas Exploration activities in North Musi Cluster, South Sumatra Basin at PERTAMINA EP Block had been inactive since Mambang Field stopped producing in 2005. However, in 2024, a recent hydrocarbon discovery was made in the area from the DPT wildcat exploration well, which flowed & tested rate of 200 BOPD and 0.6 MMSCFD from drill stem test at Grid Sand Member (GRM) Talang Akar Formation. This recent discovery has opened new opportunities for exploitation and exploration activity. This well is a stratigraphic play opener in the area, shown through the Talang Akar Formation (TAF GRM) geological model, built from well data and 3D seismic data. A robust depositional model of TAF GRM is created through integration of well data, such as Gamma Ray log Correlation, Borehole Image Interpretation, Biostratigraphy Analysis and seismic data such as Sweetness seismic attribute which in turn unveil the full stratigraphic play potential within the North Musi Cluster.
