17 August 2010 - The Tuatara-1 offshore well in western Tasman Bay has been plugged and abandoned by operator AWE Ltd after minor oil and gas shows.

AWE said minor oil shows were intermittently recorded between 1790 and 1850 metres down the Tuatara-1 well. There were also earlier reports of gas shows between 780 and 900 metres. But when wireline logs were run, no zones of economic potential were identified. Cement plugs were run prior to abandoning the well.
The final exploration well in AWE’s current New Zealand campaign, was drilled to a total measured depth of 1911 metres targeting the Moki sands within the Tuatara prospect in PEP 38524 in the southern offshore Taranaki Basin. Interest holders in PEP 38524 are: AWE 60 per cent, Roc Oil 20 per cent, Kea Oil and Gas 10 per cent and Carnarvon Petroleum 10 per cent.
AWE said earlier it will now take the Kan Tan IV semi-submersible rig back to the Tui oil field in August to carry out a workover of the Pateke-3H well which has been shut in because of a minor leak within the gas lift system. Kan Tan IV will then be used by Origin Energy to drill two wells in the Korimako and Tarapunga prospects in the offshore Northland Basin.
