Corvus field appraisal drilling confirmed more gas resources offshore Western Australia. Drillers reported a 2,093-ft gross interval, one of the largest columns to be discovered on the North West Shelf, said Santos Ltd. of Adelaide.
The Noble Tom Prosser jack up drilled the Corvus-2 well in 207 ft of water in the Carnarvon basin WA-45-R permit in which Santos has 100% interest.
TD was 13,117 ft for Corvus-2, which is 56 miles northwest of Dampier. Wireline logging indicated 804 ft of net pay across North Rankin and Mungaroo formations at 11,023-13,117 ft.
Drillers encountered higher permeability zones than in the Corvus-1 discovery well, 2 miles to the northeast. Santos reported Corvus-2 showed a condensate-gas ratio of up to 10 bbl/MMcf with carbon dioxide content of 7%.
Santos executives said Corvus could be tied back to either Devil Creek or Varanus Island gas plants.
