NZOG (New Zealand Oil & Gas Ltd) advises that the Kan Tan IV drilling rig started drilling the Tui SW-1 well at 1000 hours on 2 May 2010. At 0600 hours today (NZ time) the well was at a measured depth of 1,505 metres, where 13-3/8" casing was being run and cemented, as planned.

The Tui SW-1 well is located in mining licence PMP 38158 in the offshore Taranaki Basin, approximately 85 kilometres from New Plymouth.

The Tui SW-1 well is testing the Kapuni F10 Sand, which has proved productive at the adjacent Tui oilfield. The well is planned to be drilled to a total depth of approximately 3,900 metres. At the conclusion of drilling, Tui SW-1 will be cased and suspended as a possible future gas injection well.

A second well, Kahu-1, is to be drilled immediately following Tui SW-1.
