Australia: Cooper Energy announces successful conclusion of the Callawonga appraisal drilling campaign
03 Dec 2019
Cooper Energy has announced the successful conclusion of the four well appraisal program at the Callawonga oil field, Cooper Basin, South Australia by the PEL 92 Joint Venture. Cooper Energy has a 25% interest in the PEL 92 joint venture with the balance held by the Operator, Beach Energy.
The campaign commenced 5 November 2019, targeting information on the extent of the field to the north and east as illustrated by the well location and pre-drill field map (see below).
Results from the campaign are largely in line with pre-drill expectations and have helped define the field limits in the north and east. Callawonga-19, 20 and 21 intersected the top Namur Formation reservoir high to prognosis which, subject to a full field review, may result in increased field size and future development drilling.
Individual well results were as follows:
- Callawonga-19, located approx. 500 metres east of Callawonga-12 was plugged and abandoned with oil shows after being drilled to a total depth of 1,550 metres;
- Callawonga-20, located approx. 600 metres north-east of Callawonga-4 was plugged and abandoned with oil shows after being drilled to a total depth of 1,485 metres;
- Callawonga-21, located approx. 500 metres south of Callawonga-4 was plugged and abandoned with oil shows after being drilled to a total depth of 1,494metres; and
- Callawonga-22, located approx. 500 metres north of Callawonga-3 was plugged and abandoned as a dry hole after being drilled to a total depth of 1,477 metres.
The Callawonga appraisal campaign is to be followed immediately by a 4 well appraisal campaign at the Butlers Field, also located in PEL 92.
