Cooper Energy Limited reported Wednesday that Callawonga-11, an oil appraisal well in PPL 220 on the western flank of the Cooper Basin, South Australia, is to be cased and suspended after reaching a total depth of 5,686 feet (1,733 meters) in the Hutton Sandstone. Callawonga-11 was the second of a three-well drilling campaign targeting the Namur Sandstone.
After the completion of wireline logging operations a gross oil column of 14 feet (4.3 meters) is interpreted in the McKinlay Member and Namur Sandstone primary targets at Callawonga-11.
Callawonga-11 was a step-out well drilled 2,198 feet (670 meters) southeast from the Callawonga-9 production well to appraise a structural extension to the southern flank of the Callawonga field. The well information is currently under evaluation, however the results are expected to lead to the identification of additional development well locations.
Following Callawonga-11, EDA Rig 930 will move to drill the Sensation-1 oil exploration well in PRL 98, which is located 1.8 miles (2.9 kilometers) north of Callawonga-3. Sensation-1 has a planned total depth of 6,309 feet (1,923 meters) in the Merrimelia Formation. Drilling is anticipated to be completed within 8 days of spudding. Sensation-1 will conclude the current Cooper Basin drilling campaign.
Cooper Energy Limited holds a 25 percent interest in PPL 220 and PRL 98, with the balance held by the Operator, Beach Energy Limited.
