Second of four Wells - Completed drilling and production facility TE-B06-002 well

NuEnergy Gas Limited (“NuEnergy” or “the Company”) (ASX: NGY) is pleased to announce the successful completion of drilling for TE-B06-002 well within its Tanjung Enim Production Sharing Contract (“PSC”) Plan of Development 1 (“Tanjung Enim POD1”) contract area, in South Sumatra, Indonesia. The TE-B06002 well is the second of four planned coal bed methane (“CBM”) wells under NuEnergy’s early gas sales initiative, which targets initial gas sales of 1 million standard cubic feet per day (“mmscfd”) and represents Indonesia’s first commercial CBM development.

The well was drilled to a depth of 424 metres and five coal seams with a cumulative thickness of 47.3 metres were intersected at depths ranging between 251 and 374metres. Gas shows were observed at surface via logging equipment, confirming the presence of CBM across multiple seams.

Consistent with the first well TE-B06-001, NuEnergy has successfully installed a Progressive Cavity Pump (‘PCP’) system for the TE-B06002 well. This installation represents a critical step in advancing towards stable gas production and optimizing well performance. The installed PCP system incorporates real-time remote monitoring and control technology, allowing for data-driven adjustments to production parameters. This capability is expected to reduce downtime, enhance operational efficiency, and support long-term performance optimization.

Gas will be gathered at the surface facility and delivered to the gas processing facility upon reaching target production levels.

The drilling rig has been rigged down and mobilising to the third well site.

Pursuant to the signed Heads of Agreement with PT Perusahaan Gas Negara Tbk (“PGN”), gas produced from TE-B06-001 well, TE-B06-002 well and future two wells will be delivered via an infield pipeline to PGN’s processing and distribution facility within the Tanjung Enim POD 1 contract area. This marks a major advancement in monetising NuEnergy’s CBM assets and delivering domestically sourced, cleaner energy for Indonesia’s gas market.
