ROC Optimizes Production Rate at Cliff Head Oil Field

Roc Oil (WA) Pty Limited, a wholly owned subsidiary of ROC, advised that a workover to replace the electric submersible pump ("ESP") at the CH-10 production well at the Cliff Head oil field offshore Perth Basin was completed in December. Additionally, the installation of a new ESP at the CH-6 production well is nearing completion.

Following the installation of the larger ESP in CH-10 the Cliff Head oil field production rate has improved to approximately 5,000 bopd, with further well optimization activity in progress.
