Cooper Basin drilling success at Callawonga-12

Published by
Oilfield Technology,

Cooper Energy Limited has reported that Callawonga-12, an oil development 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 1449 m in the Westbourne Formation. Callawonga-12 targeted the McKinlay Member and Namur Sandstone. At 06:00 hours this morning, logging operations were being completed.

Callawonga-12 was drilled 230 m southeast from the Callawonga-3 production well to accelerate production from the northern part of the field. A gross oil column of 4.0 m (approximately 2 m net oil) is interpreted in the primary target McKinlay Member and Namur Sandstone.

Commenting on the well Mr Maxwell said:

“This is a pleasing result which reinforces the remaining production and development potential upside in the Callawonga oilfield”.

Following the completion of Callawonga-12, the drilling rig will depart before returning in October to drill 1 to 2 exploration wells in PRL’s 85-104.Cooper Energy Limited holds a 25% interest in PPL 220, with the balance held by the Operator, Beach Energy Limited.
