ADELAIDE, Australia – Total has discovered gas in the Bassett structure offshore northwest Australia, according to partner Santos.
The Bassett West-1 exploration well was drilled in 368 m (1,207 ft) of water on license WA-408-P in the Browse basin, 475 km (295 mi) north-northeast of Broome, and 90 km (56 mi) east-northeast of Santos’s recentCrown-1 discovery in adjacent WA-274P.
Wireline logs and sampling confirmed 7.5 m (24.6 ft) of gas pay in Jurassic sandstones on the western flank of the Bassett structure.
Santos Head of Exploration Bill Ovenden said the presence of gas with condensate and the absence of a water leg or gas/water contact was encouraging, but further work would be needed to better understand the resource potential.
“This includes greater clarity on the gas composition and the extent of this gas-bearing interval and additional potential reservoir segments across this large regional structural high,” he said.
Drilling of the Dufresne-1 well on the same license will start after Bassett West-1 has been P&A’d.
