Roc Oil Well Re-spudded Offshore China

Roc Oil (China) Company reports that since its last Stock Exchange Release on February 13, 2008, the Premium "Murmanskaya" jack-up rig has re-spudded the Wei 6-12E well as Wei 6-12E-1A in Block 22/12, Beibu Gulf, offshore China.

The well was required to be re-spudded due to problems associated with retrieving stuck drill pipe. Wei 6-12E-1A is located approximately two meters from the original hole. The well's target remains unchanged: a stratigraphic-structural prospect, approximately 1.7 kilometers east of the Wei 6-12S-1 oil discovery.

As at 6:00 a.m. on February 20, 2008 the well had been drilled to 253 mBRT and the current operation is repairing the top drive.

Wei 6-12E-1A, the second of the planned three well exploration/appraisal program in Block 22/12, Beibu Gulf, offshore China, is expected to reach the proposed total depth of approximately 2,520 mBRT by early March 2008.

Participating Interests in Block 22/12 Joint Venture are: Roc Oil (China) Company, 40% (Operator); Horizon Oil Limited, 30%; Petsec Petroleum, 25%; Oil Australia Pty Ltd, 5%.
