Ann: CBM Reserves Certification for Tanjung Enim PSC Initial POD, page-8

From NGY’s Quarterly Activities Report ended June 2025 released on 28 July 2025 on TANJUNG ENIM Production Sharing Contract (“PSC”)

During the quarter, NuEnergy Gas Limited (“NuEnergy” or “the Company”) (ASX: NGY) commenced drilling operations for the TE-B06-001 well, the first of four planned wells to be drilled under the early gas sales initiative which targets initial gas sales of 1 million standard cubic feet per day (“mmscfd”), at its Tanjung Enim Production Sharing Contract (“PSC”) Plan of Development 1 (“POD1”) contract area. A 750 horse power hydraulic drilling rig equipped with a TopDrive system for enhanced safety and operational efficiency was mobilised and commenced spudding on 25 May 2025. The well was drilled to a depth of 411 metres and five coal seams with a cumulative thickness of 47.5 metres were intersected at depths ranging between 283 and 406 metres. Gas shows were observed at surface via logging equipment, confirming the presence of coal bed methane(“CBM”) across multiple seams.

NuEnergy has also successfully installed a Progressive Cavity Pump (“PCP”) system completed with the surface facility at the well site. This installation marks the completion of drilling at TE-B06-001 well and represents a critical step in advancing towards stable gas production and optimizing well performance. The PCP system includes real-time remote monitoring and control functionality, enabling data-driven production optimisation and reduced operational downtime. Dewatering is underway, with steady gas build-up observed via casing pressure monitoring. Gas will be gathered at the surface facility and routed to the Gas Processing Facility upon achieving target production levels.

Following the completion of TE-B06-001 well, the hydraulic rig was rigged down on 27 May2025 and mobilised to the TE-B06002 well site. Rig-up activities began on 29June 2025, with spudding commencing, subsequent to the quarter, on 7 July 2025 and drilling completed as announced on 23 July 2025. The third well has been spudded on 28 July 2025 and preparations are also progressing at the fourth well TE-B01-003 drilling site. All four wells are located in close proximity to improve reservoir connectivity and maximise production efficiency.

Following the Heads of Agreement for the sale and purchase of coal bed methane between NuEnergy (as the seller) and PT Perusahaan Gas Negara (“PGN”), a leading natural gas distributor in Indonesia and a subsidiary of PT Pertamina (as the buyer), the parties finalized the terms of the Gas Sales and Purchase Agreement(“GSPA”) on 31 December 2024, under the guidance of the Special Task Force for Upstream Oil and Gas Business Activities (“SKK Migas”). The Ministry of Energy and Mineral Resources (“MEMR”) has since received SKK Migas’s recommendation for gas allocation and pricing for the Tanjung Enim early gas sales initiative. Upon MEMR’s approval, NuEnergy and PGN will proceed with the formal signing of the GSPA.
