Update Production Testing and Reserve Certification

Brisbane, Jan 13, 2020 AEST (ABN Newswire) - State Gas Limited (googlechartASX:GAS) ("the Company") refers to its previous announcements in relation to recent activities at the Reid's Dome Gas Project (PL 231), and in particular the early results of the Nyanda-4 production test.

The Company is pleased to provide an update on the results of the production testing following almost six weeks of operation. This production testing at Nyanda-4 is the first production test of the Reid's Dome Beds within (and in the region of) PL 231.

As advised, dewatering commenced on 4 December 2019, and sustained gas flows commenced soon after on 9 December, only 5 days after the commencement of dewatering.

Along with the early success at Nyanda-4, further recent successes at both Aldinga East-1A and Serocold-1 have led the Company to commence planning for this year's pilot testing program.

To this end the Company has engaged Netherland Sewell & Associates International ("NSAI") as its reserve certifier for the 2020 program.

State Gas has also conducted an audit of all results received from the production testing at Nyanda-4 to date over recent days. The Company acquired a Critical Flow Prove ("CFP") to conduct the flow rate audit and ensure the validity of data. The CFP results identified flaws in externally specified and supplied metering equipment which had led to incorrect data in previously measured and announced flow rates.

The results of this exercise reconfirmed that gas flow rates have been very positive and increased steadily as the water level in the well has been reduced, although rates were previously overstated.

As at 6am on 13 January the gas rate was 120 mscf/d. The total volume of gas produced to date is approximately 2,000 mscf.

The water level in the well continues to be slowly lowered and gas flows continue to increase in a linear trend as dewatering progresses. Currently at 702 m from surface, the fluid level remains above the level of the lower coals and sands in the well, and further increases in the gas flow rate are therefore expected. Total depth of Nyanda-4 is 1,200 m.

The volumes of water produced from the well continue to be at the lowest end of the range of water production from coal seam gas wells, indicating a minimal water management task.

Given these exceptionally high flow rates for a well that is not aided in de-watering with a sentinel well and has only been in production for less than 6 weeks, the Company will be designing this year's programme to maximise the geographical extent of the Coal Seam Gas.

The audit confirmed that, apart from the calibration of the Nyanda-4 meter, all other results remain unamended.

In other news, workover activities to complete the Serocold-1 well have been finalised, and surface facilities for the production test are now being installed. It is anticipated that the production test of the well will commence by the beginning of next week.

Further updates will be provided as further results become available during the coming weeks.

About State Gas Limited

State Gas Limited ASX:GASState 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.
