Indonesia’s upstream oil and gas regulator SKK Migas and the Ministry of Transmigration signed a formal agreement on May 4, 2026 to develop 13 new oil and gas wells within a transmigration land management area in Samboja, East Kalimantan, with drilling by PT Pertamina Hulu Sanga Sanga scheduled to begin in June 2026. The development comes as Indonesia faces sustained pressure on domestic production levels against a consumption base that has outpaced national output for more than two decades.
Key Facts At A Glance
- SKK Migas identified 13 potential new wells in Samboja, Kutai Kartanegara Regency, East Kalimantan, with estimated reserves of 0.96 million barrels of oil and 11.64 billion cubic feet of gas.
- All 13 wells will be developed by PT Pertamina Hulu Sanga Sanga, a subsidiary of Pertamina’s Upstream Subholding Regional 3 Kalimantan, which already operates 79 wells in the same area.
- The lead development well, MUT-346 OS HZ, is targeted to produce 7.3 million cubic feet of gas per day, with reserves estimated at 3.6 billion cubic feet.
- Based on an assumed gas price of $7.7 per MMBTU for 2026–2031 and an exchange rate of Rp17,000 per US dollar, the reserves are valued at approximately Rp471 billion, equivalent to around $29 million.
- Gross revenue from the development is estimated at Rp355 billion, with government revenue projected at approximately Rp87 billion after tax.
- Drilling operations are scheduled to begin in June 2026, with land management rights remaining under the Ministry of Transmigration under a Right-to-Use arrangement.
The Samboja Agreement
Indonesia’s Transmigration Ministry and SKK Migas signed a memorandum of understanding covering the utilization of transmigration land management rights in Samboja, Kutai Kartanegara Regency, for upstream oil and gas development. Transmigration Minister Muhammad Iftitah Sulaiman Suryanagara stated that the ministry would contribute to national energy self-sufficiency by enabling drilling activities on land it administers, describing the signing as a new chapter in transmigration area transformation.
SKK Migas Head Djoko Siswanto confirmed that the 13 new wells are located within the existing Sanga Sanga working area, where PT Pertamina Hulu Sanga Sanga currently manages 79 producing wells. Under the agreed arrangement, land management rights remain with the Ministry of Transmigration while SKK Migas and the ministry cooperate to facilitate development of the energy assets. Siswanto described the reserves as strategically important, noting that oil and gas remain critical to domestic energy needs and that identifying new reserves elsewhere is neither straightforward nor cost-effective.
Production Targets And Reserve Valuation
The most significant prospect among the 13 targets is the MUT-346 OS HZ development well, which SKK Migas expects to produce up to 7.3 million cubic feet of gas per day. The total gas potential across all 13 wells is estimated at 11.64 billion cubic feet, with oil reserves at approximately 0.96 million barrels. At projected gas prices of $7.7 per MMBTU for the 2026–2031 period, SKK Migas values the gas reserves at approximately Rp471 billion. Gross development revenue is estimated at Rp355 billion, with government revenue after tax projected at around Rp87 billion.
Indonesia’s Structural Energy Challenge
The Samboja development reflects a broader and persistent challenge in Indonesia’s energy sector. Indonesia has been a net oil importer since 2003, and domestic crude oil production has remained below one million barrels per day since 2007. National oil consumption stands at approximately 1.6 million barrels per day, against a production base of roughly 600,000 barrels per day, leaving the country structurally dependent on imported refined petroleum products.
Pertamina Hulu Energi, the primary engine of national upstream production, contributes approximately 69 percent of total national oil output, with a 2026 production target of 595,000 barrels per day from its portfolio. Around 80 percent of Pertamina’s fields are classified as mature, with water-cut levels reaching 70 to 95 percent, making new well identification in existing working areas such as the Sanga Sanga block an operationally lower-risk approach to adding incremental supply compared to greenfield exploration.
The Indonesian Petroleum Association has noted that activating commercially viable prospects within established working areas is more strategically immediate than new exploration, which carries longer timelines and higher technical risk. The Samboja agreement reflects this approach, extending production within a proven block using an operator already active on site, while introducing a cross-ministerial land access structure that could serve as a template for unlocking upstream development in other transmigration areas.
