RH Petrogas Limited said on Nov, 21 2025 that its 82.65%-owned subsidiary Petrogas (Basin) Ltd. has started drilling the Karim-1 exploration well in the Kepala Burung Production Sharing Contract (PSC) in Southwest Papua, Indonesia.

The onshore well, located about 23 km east of the group’s Arar production cluster, will be drilled vertically to a planned total depth of roughly 4,300 feet (about 1,311 metres). Drilling and completion are expected to take 43 days.

Karim-1 is designed to evaluate the oil potential of the Miocene Kais carbonate reservoir within a structural closure situated up-dip of the earlier Klaifi-1 oil discovery, around 7 km northwest of the new well.

After finishing Karim-1, the company’s rig will be moved to drill the Northwest Klagagi-1 exploration well, about 15 km northeast of the Arar cluster and 12 km from the Karim-1 site. Both wells are part of the firm work commitment of the Kepala Burung PSC that began in 2020.

Group CEO and Executive Director Francis Chang said preparations for the two back-to-back wells began in 2024, including securing environmental and forestry permits, site preparation and upgrading of the drilling rig to improve capacity and reliability.

Headquartered in Singapore and listed on the Singapore Exchange, RH Petrogas focuses on the exploration, development and production of oil and gas resources in the ASEAN region.
