Brisbane-based conventional gas developer State Gas Limited (ASX:GAS) is pleased to advise it has successfully completed gas flow-testing, sampling and analysis from existing gas wells at PL 231 in the Bowen Basin Central Queensland.

The flow-testing and sampling was undertaken by Kinetic Production & Wellhead Services, based in Roma, Queensland.

The three wells flow-tested and sampled were Primero 1, Aldinga North 1 and Reid's Dome-4. Drilled between 11 and 37 years ago, these existing wells are located within the northern half of PL 231.

The Company is pleased to report that, despite the wells being shut-in for such an extended period, all wells flowed significant gas, at lowest recorded stabilized rates of between 357,000 cf/d and 658,000 cf/d using a 0.500" orifice plate.

Two gas samples per well were taken from each of these wells and sent to Petrolab in South Australia for analysis. Gas composition results indicate the produced gas represents a similar composition in its natural form to that of pipeline-quality gas, with an average Methane (C1) content of approximately 96%, average Carbon Dioxide (CO2) content of approximately 1.5% and very low levels of interts.

The similar reservoir pressure (166 - 167psig) and gas composition results for all the wells also implies that the reservoir is connected between each of the wells tested, providing a positive indicator for future gas production.

The gas flow-testing and sampling conducted in mid-December relates to the shallow Cattle Creek Formation, which commences at approximately 130 metres from surface and does not include gas targets within the deeper Reid's Dome Beds situated beneath the Cattle Creek horizon.

The Company is also pleased to advise that the reprocessing of historical seismic survey data by DownUnder GeoSolutions is currently underway and is expected to be complete during February 2018. With the seismic re-interpretation and the recent flow-testing and gas composition results, well sites will be selected for the 2018 drilling campaign.

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 prog
