Origin To Abandon Tarapunga-1 Well
Origin Energy advises that the Tarapunga-1 exploration well has been drilled to a total depth of 1,000 m and at 06:00 hours NZDST 12 November 2010 wireline logging operations were being conducted. The well was drilled vertically using the semi-submersible drilling rig Kan Tan IV which is being managed for Origin by Australian Drilling Associates (ADA).
Gas shows were observed within the target interval, but no intervals of economic significance were identified.
Abandonment operations have commenced and the Kan Tan IV drilling rig will be released and demobilised to Australia.
