The Upstream Oil and Gas Regulatory Task Force (SKK Migas) and Contractor Contract Cooperation (KKKS) Jindi South Jambi B Co. Ltd. have discovered hydrocarbons in the form of gas through re-entry exploration activities and re-entry layer testing at the Bungin-1 exploration well in Bengku Village, Bajubang District, Batanghari Regency, Jambi Province.
The Bungin-1 well re-entry exploration was carried out to test and re-evaluate in the long term (prolonged test) the hydrocarbon content found in the main objective in the Pre-tertiary basement formation by re-perforating and adding one new perforation so that gas reserves can be identified.
Head of Drilling and Well Division at SKK Migas, Surya Widyantoro, said the Bungin-1 Well (re-entry) was first drilled in 1980 by Chevron Pacific Indonesia and Gulf Oil International with a final depth of 10,337 feet Measured Depth (ftMD).
Re-entry was continued by Oil Contractor Jindi South Jambi, currently performing re-testing activities of the layer test in the exploration well using Surface Well Test and Slickline.
“Results of re-testing on the layer test reveal that the Bungin-1 well (re-entry) discharged gas of 9.45 million cubic feet of gas per day (MMSCFD) at a choke opening of 48/64 inches,” Surya said in a statement as quoted on Tuesday, October 22, 2024.
SKK Migas and Jindi South Jambi B are still conducting Pressure Build-Up (PBU) Test or pressure testing on the well. Both have planned to continue the re-entry layer test activity at the Bungin-1 exploration well for the next 40 days starting on October 18, 2024.
Head of Program and Communication Division at SKK Migas, Hudi D. Suyodipuro, said that this gas discovery was the second discovery in Southern Sumatra, after the previous oil discovery in Banyu Lencir, Muara Enim on October 14, 2024.
“Exploration will continue so that energy security can be achieved. SKK Migas also continues to encourage the monetization of projects that have been and will be running to be realized immediately,” Hudi said.
