Cooper Energy Spuds Callawonga-10 Well in Cooper Basin in South Australia

Cooper Energy Limited reported Monday the commencement of a three well drilling campaign in PPL 220 and PRL 98 on the western flank of the Cooper Basin, South Australia with the spud of Callawonga-10 April 25 at 10:30 hours. At 06:00 hours today, the well was being circulated clean prior to cementing 9.625 inch surface casing at 2,234 feet (681 meters).

The drilling campaign includes the following development, appraisal and exploration wells:

  • Callawonga-10, an oil development well located 919 feet (280 meters) east of Callawonga-2, to accelerate production from, and to potentially add reserves to, the southern area of the Callawonga Field (PPL 220). Total depth is prognosed at 4,856 feet (1,480 meters)
  • Callawonga-11, an oil appraisal well 2,198 feet (670 meters) southeast of Callawonga-9, is a significant step out from existing wells. This well will appraise the potential for additional oil reserves in the southeastern area of the field. Total depth is prognosed at 5,676 feet (1,730 meters)
  • Sensation-1 (PRL 98), an oil exploration well, will test a mapped anticlinal structure located 1.8 miles (3 kilometers) north of the Callawonga Field. Total depth is prognosed at 6,309 feet (1,923 meters)

The prolific Namur Sandstone is the primary target in all three wells.

Callawonga-10 is anticipated to be completed within 8 days of spud and the three-well drilling campaign to be completed by the end of May.

Cooper Energy holds a 25 percent interest in PPL 220 and PRL 98 with the balance held by the Operator, Beach Energy Limited.
