                             STOCK EXCHANGE RELEASE

                 DRILLING UPDATE: WEI 6-12W-1 EXPLORATION WELL,
                          BLOCK 22/12, OFFSHORE CHINA

Roc Oil (China) Company, a wholly owned subsidiary of ROC, advises that since
its last Stock Exchange Release on 23 January 2008, the Wei 6-12W-1 exploration
well in Block 22/12 in the Beibu Gulf, offshore China, has drilled to a Total
Depth of 2,333 mBRT and wireline logging has been completed. Drilling and log
data indicate that Wei 6-12W-1 well has not encountered any hydrocarbons and the
well has been plugged and abandoned.

Later this week, the Premium "Murmanskaya" jack-up drilling rig will commence
drilling Wei 6-12E-1, the second well in the three well drilling programme,
which will test a structural-stratigraphic prospect 1.7 kilometres east of the
Wei 6-12S-1 oil discovery.

Commenting on the Wei-6-12W-1 drilling results, Dr John Doran, ROC's Chief
Executive Officer, stated that:

"As stated at the beginning of the well, although stratigraphic traps can offer
high reward they invariably carry increased risk. In this case, the risk won
over the reward."
