Sydney-listed State Gas on March 16 said its Nyanda-4 coalbed methane (CBM) well at its 100%-owned Reid’s Dome project (PL 231) in the Bowen basin in Central Queensland flowed record gas.  

The company said that the Nyanda-4 well has provided “exceptional results” overnight, producing a total of 620,000 ft³ in the previous 24 hours. Drilled in late 2018, the Nyanda-4 well was placed on test for two periods last year; in each case, gas production was interrupted by pump breakdowns after six and nine weeks respectively.

“Production in the current test has exceeded previous rates achieved, on both a daily production and instantaneous basis,” State Gas said. 

The company is undertaking production testing of three CBM wells in the Nyanda area at Reid’s Dome in order to appraise that area for early development. Nyanda-7 is displaying positive early signs, with 5000 ft³/day recorded. Meanwhile, Nyanda-8 gas flows also continue to build, producing 31,000 ft³/day over 24 hours, it said. 

“Last week I advised we had ‘cracked the code’ at Reid’s Dome and these results truly confirm it,” State Gas executive chairman, Richard Cottee, said. “The rates we are seeing from Nyanda-4 are well above the indicative threshold for a commercial well, and I am confident the area will prove commercial.” 

State Gas also said that the Secure Well Services Rig 2 was mobilised to the site on March 15 to undertake a workover at the Serocold-1 well. This well will be cleaned out and a new pump installed, prior to a production test to establish the producibility of gas in this central area of PL231. 

Planning is also progressing for drilling at the company’s new Rolleston West permit (ATP 2062), located to the north-east of PL 231, with drilling anticipated to start in mid to late April, it said.
