JAKARTA, INDONESIA AND DANVILLE, CA, May 26, 2026 (GLOBE NEWSWIRE) -- Indonesia Energy Corporation (NYSE:INDO) ("IEC"), an oil and gas exploration and production company focused on Indonesia, today announced that rig mobilization is complete on the K-29 well, the first of two planned wells during 2026 at its 64,000 acre Kruh Block. The rig has been successfully set up at the wellsite and centered on the hole. Pictures and videos can be viewed on the IEC website: https://ir.indo-energy.com

Indonesia's oil industry has recently faced significant operational challenges, including flooding due to anomalous weather and diesel fuel shortages related to the conflict in the Middle East. These conditions, combined with increased competition for qualified and fully certified rig personnel, have contributed to delays across the sector.

Despite these challenges, IEC has successfully advanced preparations for drilling operations during 2026. IEC is currently estimating the following near term drilling timeline for the K-29 well:

Installation and rig setup completed — early June 2026
Rig-up and crew readiness completed — mid-June 2026
Function testing completed — mid to late June 2026
Government inspection completed — late June 2026
Spud date (start of drilling) — late June 2026

Following completion of the K-29 well, IEC plans to commence drilling activities at the WK-5 as part of a Kruh Block drilling program.

This drilling campaign comes at a favorable time for IEC as global oil prices have strengthened amid ongoing geopolitical tensions in the Middle East.

Mr. Frank Ingriselli, IEC's President, commented "We are very pleased with our operational team's ability to successfully navigate the unexpected logistical and industry-wide challenges affecting Indonesia and global markets. We remain focused on executing our drilling program efficiently and will continue to keep the market informed as we move through this important operational phase. We believe our Indonesia assets, combined with the current oil price environment, position IEC well to advance our strategy of maximizing investment returns and enhancing shareholder value."
