The PESA SA/NT Branch welcomed Trevor Brown and Nathan Parker to give 36 members an update on Omega’s activity in the Taroom Trough, onshore Queensland.
Trevor introduced the company and gave an overview of the geology of the Bowen Basin, and this was followed by Nathan giving a very interesting history of the oil and gas industry in the region which started in the late 1800s.
This month has seen the Taroom Trough hit the headlines as new exploration acreage was awarded and drilling results were announced. We asked Dr Alison Troup, a Queensland based geologist with over fifteen years of extensive experience working on basin research projects across Queensland, to give us the background on this basin.
The Bowen Basin is an elongate Early Permian to Middle Triassic sedimentary basin that extends from Collinsville in central Queensland into northern New South Wales. The whole basin occupies approximately 160,000 km2, with the southern half concealed underneath the Surat Basin.
Elixir Energy this month announced success at their Lorelle-3 pilot, interpreting 148m of total net pay across the primary, secondary and tertiary Permian reservoir targets, with associated elevated mudgas readings. The Lorelle-3 pilot was drilled in ATP2056 within Queensland’s Taroom Trough. Elixir Energy hold a 50% interest in ATP 2056 and are operator of the Lorelle 3 appraisal well. Santos hold the remaining 50% interest in the permit and will be operator of the permit thereafter.
Elixir Energy interpret the primary target, the Tinowon Dunk sandstone, to be 56m thick with 28m net pay interpreted, supported by elevated mud gas readings and fluorescence in cuttings.
