Rougemont-3 Enters Coal Seam with Strong Gas Shows
Brisbane, Sep 26, 2022 AEST (ABN Newswire) - State Gas Limited (ASX:GAS) (STGSF:OTCMKTS) advises that its Rougemont-3 horizontal well entered the target coal seam overnight and is currently making good progress through the seam towards its intersect point with Rougemont-2.
Strong gas shows, (maximum 13.8%, average 11%-12%) at 99% methane are being observed from the coal seam traversed.
As indicated in recent announcements, State Gas is currently drilling the Rougemont-3 horizontal well to confirm the potential of the Rougemont area within its Rolleston-West Project (ATP 2062).
The well will be drilled laterally through the coals of the Bandanna Formation to meet the vertical Rougemont-2 well. Once completed, the wells will be placed on production as a combined vertical - horizontal pair.
The well reached target vertical depth on 20 September, following which the top hole was cased and cemented to prepare for drilling of the lateral. The target coal was entered as planned and drilling proceeds under close monitoring to optimise well length within the seam.
About State Gas Limited
State Gas Limited (ASX:GAS) is a Queensland-based developer of the Reid's Dome gas field, originally discovered during drilling in 1955, located in the Bowen Basin in Central Queensland. State Gas is 100%-owner of the Reid's Dome Gas Project (PL-231) a CSG and conventional gas play, which is well-located 30 kilometres southwest of Rolleston, approximately 50 kilometres from the Queensland Gas Pipeline and interconnected east coast gas network.
Permian coal measures within the Reid's Dome Beds are extensive across the entire permit but the area had not been explored for coal seam gas prior to State Gas' ownership. In late 2018 State Gas drilled the first coal seam gas well in the region (Nyanda-4) into the Reid's Dome Beds and established the potential for a significant coal seam gas project in PL 231. The extension of the coal measures into the northern and central areas of the permit was confirmed in late 2019 by the Company's drilling of Aldinga East-1A (12 km north) and Serocold-1 (6 km to the north of Nyanda-4).
State Gas is also the 100% holder Authority to Prospect 2062 ("Rolleston-West"), a 1,414 km2 permit (eight times larger than PL 231) that is contiguous with the Reid's Dome Gas Project. Rolleston-West contains highly prospective targets for both coal seam gas (CSG) and known conventional gas within the permit area. It is not restricted by domestic gas reservation requirements.
The contiguous areas (Reid's Dome and Rolleston-West), under sole ownership by State Gas, enable integration of activities and a unified super-gasfield development, providing economies of scale, efficient operations, and optionality in marketing.
State Gas is implementing its strategic plan to bring gas to market from Reid's Dome and Rolleston-West to meet near term forecast shortfalls in the east coast domestic gas market. The strategy involves progressing a phased appraisal program in parallel with permitting for an export pipeline and development facilities to facilitate the fastest possible delivery of gas to market. State Gas' current focus has been to confirm the producibility of the gas through production testing of the wells.
