Cooper Energy Limited (ASX: COE) reports that the Callawonga-8 well, in PEL 92 on the western flank of the Cooper Basin, has penetrated 7 metres of gross oil column in the McKinlay Member and Namur Sandstone.
The well, which has been drilled to a total depth of 1,708 metres, will be cased and suspended for completion as an oil producer.
Cooper Energy Executive Director, Hector Gordon said "Callawonga-8 is an excellent result. The well came in on prognosis and is expected to be a good oil production well in the southern area of the Callawonga field."
After Callawonga-8 is cased and suspended the drilling rig will leave PEL 92 briefly before returning to drill two further exploration wells in the permit before the end of June 2013.
