A joint venture between China’s CNOOC and Australia-based Roc Oil hit a payzone at the WZ12-10-2 well, its second Beibu Gulf well in offshore China.

Wireline evaluation data confirmed a “high porosity net oil pay” of about 11 meters total vertical depth at the targeted Jiaowei formation.

The well was drilled by the HYSY 935 rig to a total depth of 5,216 feet where it intersected a granite basement.

The results of the drilling will be evaluated to assess how the find should be tied into the Beibu project.

WZ12-10-2 was plugged and abandoned on October 12.

The HYSY 935 rig will move from the site.

The WZ12-10-2 well is located about one mile east northeast of the existing WZ12-8W platform.

Roc Oil said the new reservoir will extend the longevity of the Beibu Gulf project and support the integration of the WZ12-8 East development into the larger project.
