PetroChina’s Gemah-81 Well Delivers 4.8 MMscfd in Strong Initial Production Test

Feb 22, 2026


PetroChina International Jabung Ltd. (PCJL) has successfully completed the initial production test of the Gemah-81 development well in the Jabung Working Area, Jambi, marking another milestone for Indonesia’s upstream oil and gas sector. The drilling activity was conducted under the supervision of SKK Migas, the country’s upstream oil and gas regulator.

Head of SKK Migas Djoko Siswanto confirmed the positive test results, highlighting the well’s strong production performance following completion on February 11, 2026.

Based on well test analysis conducted at a 32/64-inch choke, Gemah-81 produced 4.8 million standard cubic feet per day (MMscfd) of gas at a wellhead pressure (WHP) of 1,080 psig, along with approximately 400 barrels per day (bpd) of condensate. The well targets three reservoirs, with the primary zone located at a depth interval of 7,259–7,281 feet measured depth (MD). The results indicate promising hydrocarbon potential within the Gemah field.

To accelerate production, PetroChina plans to connect the well to the existing Gemah Station production facility within approximately two weeks. The tie-in will involve the installation of around 300 meters of pipeline, enabling the well to commence regular production promptly.

Building on this success, the company is scheduled to drill two additional wells — Gemah-85 and NEB-85 ST — within the next month. SKK Migas expressed hope that these wells will deliver even higher production rates, further strengthening output from the Jabung Block.

Looking ahead, PetroChina reaffirmed its commitment to expanding exploration activities and optimizing existing assets in the block through technology deployment, cost efficiency, and collaborative efforts, supporting sustained production growth in the years to come.
