SYDNEY, Australia -- Roc Oil (China) has begun a multi-well exploration/appraisal drilling program in block 22/12, Beibu Gulf, offshore China.

The jackupMurmanskaya is drilling the Wei 6-12W-1 well on the Wei 6-12 West prospect, a stratigraphic-structural feature northwest of the Wei 6-12S-1 oil discovery. The well, which is in 30 m (98 ft) of water, is expected to reach 2,425 m (7,956 ft) TD later this month.

The second well in the program will test the Wei 6-12 East prospect, a structural-stratigraphic feature east of the Wei 6-12S-1 oil discovery. The third well will be Wei 12-2-2, which will appraise a structure in the southern part of the block that tested oil in 1993.

According to the company, there is a potential for a fourth well in the form of a sidetrack/step-out if one of the first three wells makes a discovery that requires immediate appraisal. All of the wells will be operated by ROC using theMurmanskaya.

The entire drilling program is expected to be completed by the end of 1Q 2008.

Participating interests in block 22/12 joint venture are:
Roc Oil (China) Co. - 40% (operator)
Horizon Oil - 30%
Petsec Petroleum - 25%
