Roc Oil Says Cliff Head Producing at Rates Better Than Expected

Roc Oil says the Ensco 67 has completed development drilling of the six production wells and two water injection wells at the Cliff Head Oil Field offshore Australia.

The field is producing at a rate that is better than expected, with only four of the six production wells currently on stream, producing an average in excess of 12,000 barrels of oil per day.

Following completion of development drilling activities at Cliff Head, the Ensco 67 relocated to Moondah-1 in TP/15.

Moondah-1 is located 17 km from Cliff Head and 4 km offshore from Dongara, in a water depth of 12 meters and has a planned Total Depth of 1,330 meters.

Moondah-1 will target Late Permian reservoir sands in a large rotated fault block in the northern part of the Beagle Ridge.

On completion of the Moondah-1 exploration well, the rig will drill the Frankland-1 exploration well in WA-286-P. On current rig timing the program is expected to complete during August 2006.

A further well, Perserverance-1 in WA-325-P, is expected to be drilled if rig timing permits.
