Jakarta, CNBC Indonesia – Upstream Subholding through PT Pertamina Hulu Energi Offshore North West Java (PHE ONWJ) managed to find a treasure trove of oil and gas reserves from the drilling of the GQX-1 exploration well in the North Java waters. The exploration well GQX-1 is located approximately 17 km from the existing MM field production facility.
Director of Exploration of PT Pertamina Hulu Energi (PHE) – Subholding Upstream, Medy Kurniawan explained that the GQX-1 well which was drilled at the end of April 2022 reached a final depth of 2958 feet Measured Depth (ftMD) in the middle of May 2022.
This well was successful in discovering oil and gas through the Drill Stem Test (DST) #1 which was conducted in a shallow marine sandstone reservoir of the Main Formation.
“From the results of the First Layer Content Test, a gas flow rate of 3.6 million standard cubic feet of gas per day (MMSCFD) and oil 108 barrels per day (BOPD) will be obtained. The Second Layer Content Test/DST#2 will then be carried out at intervals of 2494-2519 ftMD in the MR-26 layer,” he said in a written statement quoted on Friday (3/6/2022).
The discovery of reserves from the GQX-1 well complements the successful discovery of previous reserves in 2022, namely Sungai Gelam Timur-1 (SGET-1) wells in Jambi, Manpatu-1X in Mahakam, and Wilela-001 in South Sumatra.
In 2021, Upstream Subholding succeeded in drilling 12 exploration wells. In 2022, Upstream Subholding seeks to improve performance through an aggressive exploration well drilling work plan of 29 wells, or 242% compared to the realization in 2021.
Medy revealed that in the exploration strategy, Subholding Upstream has three main initiatives. The three main strategies include, among others, the existing Working Area (WK) assets where exploration contributions are needed to maintain and increase existing oil and gas production.
Furthermore, the New Ventures strategy is where Pertamina’s Upstream Subholding seeks new exploration potential. Lastly, the partnership strategy for risk & cost sharing as well as technology & knowledge transfer through accelerated domestic and international collaboration and joint bidding processes.
