The company made the discovery while drilling the WZ6-12N-1 well which is located in 29m of water.
ROC Oil has drilled the well to a total depth of 1,605m using the HYSY 931 rig and encountered 52m net oil pay in the well’s primary objectives and an additional 7m net oil pay in shallower reservoirs.
The company encountered gross sand thickness of 79m in the Weizhou formation with cumulative oil pay of 59m.
The new oil discovery in the T32L reservoirs is the thickest reservoir comprising of three sand units with a net pay of 46m.
ROC also discovered shallower T30 and T30D oil zones which contribute an additional 7m of oil pay, whereas further 6m T31C sand is a now proven field extension of the T31C oil reservoir encountered in the original WZ 6-12-1 well.
ROC CEO Alan Linn said the company has discovered oil at multiple levels from the exploration well which is drilled as a part of its Beibu exploration campaign.
"The now larger WZ6-12 North field will be fully developed as part of the combined WZ 6-12 and WZ 12-8W field development, which is currently underway," Linn added.
The company will plug and abandon the well after completing wireline logging and move the rig to the A6 exploration location on the WZ 6-12 South field.
