Update Production Testing and Reserve Certification
Brisbane, Jan 13, 2020 AEST (ABN Newswire) - State Gas Limited (
ASX: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: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.
