The company said on Monday the WZ6-12-A7 deviated step-out exploration well in Block 22/12 hit 10.4 metres of net oil pay in the Weizhou formation associated with the Sliver prospect.
The well was also said to have intersected 79 metres of net water wet sands, with oil shows in the underlying Liushagang formation with up-dip potential remaining.
Production lining is currently being run to enable future completion and tie-in for production, Roc said.
