Cooper Spuds Turton Well

Cooper announced that the Turton-1 exploration well in PEL92 spudded at 17:00 hours on Saturday May 28, 2011. The surface hole has been drilled to 638 meters and the current operation is running the surface casing.

The well's primary objective is the Namur Sandstone with secondary objectives in the Birkhead and Poolowanna Formations. Turton-1 is located 11 km to the southwest of the Butlers-1 and 14.1 km to the west of the Brighton-1 wells. The well will be drilled to a total depth of about 1,745 meters and is expected to take 8 days to drill and evaluate.

The Namur Sandstone primary target, which is the oil reservoir in the Butlers oil field, is estimated to contain 4.661 million barrels of Prospective Resources (P50). The deeper formations would be expected to add to this estimate if they result in discovery.
