Drilling Commences at Worrior-10 Appraisal Well in Cooper Basin in SA

Cooper Energy Limited disclosed Friday that Worrior-10 appraisal well, targeting the Patchawarra Formation on the flank of Worrior field in PPL 207 in southern Cooper Basin, South Australia, was spud at 9:15 am Feb. 27 and at 6:00 am Feb. 28 was drilling ahead at 1,033 feet (315 meters). The well has a prognosed total depth of 5,872 feet (1,790 meters) and is expected to take 14 days to drill, evaluate and complete.

This was the first Patchawarra Formation oil production at the Worrior field. Worrior-10 is targeted to appraise the areal extent of the Patchawarra Formation oil pool. The well is located 2,296 feet (700 meters) north-west of Worrior-8 and adjacent to Pando-1 drilled in 1966 that recovered 498 feet (152 meters) of gas and oil cut muddy water in the drill pipe on DST from the Patchawarra Formation.
