en.Wedoany.com Reported - Recently, Bass Oil officially spudded the Bunian 6 development well at the Tangai-Sukananti KSO oil field onshore South Sumatra, following the completion of safety reviews and compliance certifications. After installing a 20-inch conductor pipe at a depth of 46 meters, the rig is now drilling the surface hole.

Bunian 6 is expected to reach a total depth of approximately 1,820 meters within 30 days, after which it will be completed and directly brought into production. Bass Oil considers the well to be low-risk and anticipates that after it comes online in early July, the total production from the KSO field will increase from the current 250 barrels of oil equivalent per day to 750 barrels of oil equivalent per day, with Bass Oil's net share rising from 140 barrels of oil equivalent per day to 410 barrels of oil equivalent per day.

The well primarily targets the TRM3 sandstone reservoir, with an expected initial production rate of 500 barrels of oil equivalent per day. Bunian 6 will also penetrate secondary GRM and K reservoirs—zones that have already produced oil or been tested in other wells within the field, providing supplementary data for evaluating production and reserve potential. The well location was selected near the structural crest to accelerate reservoir drainage, a plan confirmed by comprehensive field studies, including reprocessing of Sukananti 3D seismic data and advanced seismic attribute analysis. Additionally, the study identified further drilling targets in the Bunian West and Bunian North West areas.
