Santos discovered gas condensate at its Lasseter-1 exploration well in block WA-274-P, located in the Browse basin, offshore Western Australia. The well reached a total depth of 5329 m and was drilled in 404 m of water. Wireline logging has confirmed 78 m of net pay over the Jurassic-aged Lower Vulcan and Plover intervals, between 4880 and 5285 m measured depth. Multiple independent hydrocarbon columns have been detected, including an estimated 250-m column for the Lower Vulcan reservoirs. Multiple hydrocarbon samples have been recovered; initial analysis confirms a condensate-to-gas ratio in the range of 10 to 25 bbl/MMcf.
