ORIGIN Energy’s upcoming drilling campaign in the Bass Basin has been pushed back to September after the contracted semi-submersible Kan Tan IV drilling rig was damaged.
Minority partner Innamincka Petroleum said the rig sustained damages to the aft crane and crane boom while preparing for the two-well drilling campaign in Port Geelong.
The drilling campaign was expected to start at the end of the July.
According to Innamincka, the rig will remain on zero rate while repairs are carried out.
The two-well campaign includes the drilling of the Trefoil-2 appraisal well and the Rockhopper-1 exploration well in T/18P.
Trefoil has estimated resources of about 220 petajoules of gas and 14.5 million barrels of liquids while Rockhopper has about 200PJ of gas and 13MMbbl of liquids.
Following the drilling in the Bass Basin, Kan Tan IV will move to New Zealand, where it will drill at least two wells for two joint ventures operated by Australian Worldwide Exploration before drilling two Northland wildcats for Origin.
Origin Energy holds a 39% interest in T/18P and is operator. AWE has 47.5% while Innamincka holds the remaining 5%.
