Drilling Started at Cooper's Parsons-5 Well

Cooper announced that the Parsons-5 appraisal/development well in PEL92 spudded at 3:00 am Friday, June 24, 2011. PEL92 lies in the north of South Australia on the western margin of the Cooper Basin. The current operation is drilling the surface hole.

Parsons-5 is targeting the Namur oil reservoir and is to be located 2.1 km to the north of the Perlubie-1 and 1.1 km to the south of Parsons-4 discovery wells. The well will be drilled to a total depth of about 1,358 meters and is expected to take approximately 8 days to drill and complete.

The Parsons South oil field is currently producing about 50 barrels of oil per day from the Parsons-2 discovery well in the Namur reservoir. Parsons-5 will be drilled at the crest of the mapped structure of the field. The well is expected to more efficiently develop the field and accelerate production.
