Beach Energy Ltd., Adelaide, discovered gas the Trigg Northwest 1 well in exploration license EP 320, onshore Perth basin, Australia. The well will be cased and completed for future testing of productivity, connected volumes, and commerciality.
The well, the fourth in the Perth Basin gas exploration campaign and the second Beach-operated well, was drilled to a total depth of 5,000 m and intersected gas in the target Kingia Sandstone reservoir. It was drilled after Trigg 1 found no producible hydrocarbons in June (OGJ Online, June 7, 2023).
Logging acquired while drilling shows net gas pay of 6 m across a 49-m gross section in the Kingia sandstone reservoir. Gas was sampled from the Kingia reservoir using wireline tools and recovered to surface.
No gas pay was interpreted in the secondary High Cliff and Wagina reservoirs, the company said.
Following casing and completion, the rig will move to the Tarantula Deep 1 well location, about 16 km west of Trigg Northwest 1.
The 174,000-sq km Perth basin encompasses both onshore and offshore parts of southwestern Western Australia. The basin extends about 1,300 km from south of Perth to its northern tip offshore from Carnarvon.
Beach’s Perth basin operations consist of the Waitsia project (operated by Mitsui E&P Australia) and Beharra Springs projects (operated by Beach Energy).
Beach is operator of EP320 (50%) with partner Mitsui E&P Australia (50%).
