Roc Oil has struck multiple hydrocarbon pays in the Weizhou formation in the Beibu Gulf offshore southern China, the Australian explorer announced on 5 November 2012.

The WZ6-12-A6 deviated step-out exploration well reached a total depth of 2,658 m on the northern flank of the WZ6-12 South field where water depths range from 25-40m. The well, drilled by the HYSY 931 rig, intersected a total of 58 m (TVD) of net oil pay. Roc said the thickest individual pay measured 38 m.

The exploration well is the second of three planned in the area. In October, Roc announced the WZ6-12N-1 exploration well hit 52m of net oil pay in its primary objectives and an additional 7m net oil pay in shallower reservoirs. Drilling on a third exploration well, WZ6-12-A7, is underway, Roc said. The company aims to test the Sliver and Luishagang prospects to the north of the WZ6-12 South field.

Roc Oil China operates the Beibu Gulf block 22/12 with 40% interest. Its joint venture partners are Horizon Oil (55%) and Oil Australia (5%). CNOOC can elect to participate up to 51% in any discoveries made.
