Rougemont-3 Well Completed
Brisbane, Oct 24, 2022 AEST (ABN Newswire) - State Gas Limited (ASX:GAS) (STGSF:OTCMKTS) advises that it has completed the drilling of the Rougemont-3 dual lateral well, with the rig released on Saturday.
The second lateral in the well has been successfully drilled to intersect the Rougemont-2 vertical well. It has now been lined to facilitate production.
The lateral achieved 97% within the target coal seam, resulting in 1130m exposure to the reservoir. Together the two laterals provide direct access to ~ 2400m of coals.
Gas shows (99% methane) in drilling fluid during drilling of the second lateral averaged a very promising 15 - 19%, indicating the coals are gas saturated. The average over both laterals was ~20%, boding well for gas production once testing starts.
Testing of the combined Rougemont-2 and -3 well pair will commence once Rougemont-2 has been recompleted and a new pump installed. This is expected in the next few weeks, subject to weather conditions.
Testing will commence with the water level in the wells being drawn down slowly to optimise production. Initial gas flows are expected to commence within the next 2-3 months.
The Rougemont-3 horizontal well is being drilled to confirm the gas production potential of the Rougemont area within State Gas' 100%-owned Rolleston-West Project (ATP 2062) and to provide gas for a future pipeline to connect the project area with the east coast gas pipeline network.
The well targets the coals of the Bandanna Formation, in commercial production at the Arcadia Valley to the south-east.

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.
