The 2C Recoverable Resource booking was independently certified by resource/reserve auditor ERCE Australia Pty Ltd, increasing the total 2C recoverable gas resources for the Grandis Project by 17% to 1,715 BCF.
Given the first-time recognition of contingent resources in the deep coals, the total 2C gas in place has increased 120%, to 58,137 BCF.
Deep dry coals
“Investigating the potential of the deep dry coals in the Taroom Trough was one of the key objectives for our Daydream-2 vertical well and to make a very material contingent resource booking from the first well that sought to do so is a great outcome for Elixir – and the broader play,” Elixir Energy managing director Neil Young said.
“The massive extent of the gas in place in these deep coals – more than 30 trillion cubic feet – illustrates the incredible resource upside in this play.”
Elixir says the deep dry coals of the Kianga Formation and Back Creek Group are one of the primary targets of the Daydream-2 well, drilled and tested in 2023 and 2024 – the well-identified notable gas content in the coal during drilling.
Subsequent stimulation and production testing flowed gas from isolated coals for the first time in the Taroom Trough, at depths between 3,698 and 3,786 metres.
The company says this gas had a different signature to that from sandstones, which were also tested in the well, forming a key foundation for the gas in the deep dry coals to be certified as a contingent resource.
