Nyanda-8 Evaluation
Brisbane, Jan 6, 2021 AEST (ABN Newswire) - State Gas Limited (
ASX:GAS) is pleased to advise the initial results of the second well in its Phase 2 drilling campaign, Nyanda-8, at its 100%-owned Reid's Dome Gas Project (PL 231) in the Bowen Basin in Central Queensland.
Nyanda-8 is approximately 2.2 km south-west of the successful Nyanda-4 well, and together with Nyanda-7 (approximately 2.6km north of Nyanda-4 - see Figure 1*), was drilled as a coal seam gas (CSG) well as part of the Company's program to appraise the Nyanda Focus Area1 within PL231 for early development.
Nyanda-8 reached the targeted Total Depth of 1200m on 3 January 2021, following spud on 29 December 2020. Wireline logs indicate the well has intersected 19.7m net coal with open fractures apparent on the image log, exhibiting good potential for CSG production.
The results of both Nyanda-7 (as announced on 31 December 2020) and Nyanda-8 are within the expected range based on data for Nyanda-4, where testing in late 2020 recorded gas production at rates approaching 500,000 cubic feet per day2. All three wells have intersected good quality coals, with seams of similar thicknesses and depths, confirming the widespread presence of gas-bearing coal seams and significant net coal within the Nyanda Focus Area.
The next step in the appraisal of the Nyanda Area is to undertake production testing of the two new Nyanda wells and recommence the production test at Nyanda-4. To this end, the Completion/Workover Rig has commenced operations at Nyanda-4 to enable the production test to recommence, following which it will install pumps in both Nyanda-7 and Nyanda-8. All three wells are anticipated to be dewatering by the end of January to enable gas production.
The drilling rig is currently completing installation of casing at Nyanda-8, following which the crew will demobilise while the current La Nina weather event is at its peak. When an appropriate weather window opens, the crew will return and drill the proposed Aldinga-2 well in the northern area of PL 231, and Serocold-3 in the central area.
Commenting on the positive initial results State Gas Executive Chairman Richard Cottee provided some context: "The aim of this initial phase of our present drilling campaign was to prove up an initial Nyanda Area production zone with step out wells more than 2 km to the north (Nyanda-7), and south (Nyanda-8), of the proven Nyanda-4."
"To say that the results to date are encouraging would be an understatement. The geological parameters at Nyanda-7 appear to be better than Nyanda-4, whilst at Nyanda-8 they appear to be roughly equivalent."
"In testing last year, Nyanda-4 delivered gas production at rates approaching 500,000 cubic feet per day, which is a high benchmark for CSG."
"With all three wells expected to be on production testing by Australia Day we hope to be in a position to confirm our confidence shortly thereafter", said Mr Cottee.
Mr Cottee also commented on the campaign: "Conditions have been extremely trying with the onset of the wet season coming early, but it is testimony to the dedication of our drilling team that the platform for production testing of the initial production zone has reached this milestone."

About State Gas Limited
State Gas Limited (ASX:GAS) (OTCMKTS:STGSF) is a Queensland-based gas exploration and development company with highly prospective gas exploration assets located in the southern Bowen Basin. State Gas Limited's mission is to support east coast energy markets through the efficient identification and development of new high quality gas assets.
It will do this by applying an agile, sustainable but low-cost development approach and opportunistically expanding its portfolio in areas that are well located to gas pipeline infrastructure.
State Gas is 100%-owner of the contiguous Reid's Dome (PL-231) and Rolleston-West (ATP 2062) gas projects, both of which contain CSG and conventional gas. The Projects, together some 1,595km2 , are located south of Rolleston, approximately 50 and 30 kilometres respectively from the Queensland Gas Pipeline and interconnected east coast gas network. State Gas intends to accelerate commercialisation of these assets through the application of an innovative virtual pipeline ("VP") solution which will see the Company transport compressed gas by truck to existing pipeline infrastructure or to an end user.
State Gas also holds a 35% interest in ATP 2068 and ATP 2069 in joint venture with Santos QNT Pty Ltd (65%). These two new areas lie adjacent to or in the near vicinity of State Gas and Santos' existing interests in the region, providing for the potential of an alignment in ownership interests across the region over time and enabling synergies in operations and development.
State Gas is also participating in a carbon capture and sequestration initiative with minerals explorer Rockminsolutions Pty Ltd in respect of EPM 27596 which is located on the western border of ATP 2062. This project is investigating the potential of the unique basalts located in the Buckland Basaltic Sequence (located in EPM 27596) to provide a variety of in-situ and ex-situ carbon capture applications.
