Pateke-4H drilling update 4 March

Posted on 4 March 2014

The operator of the Pateke-4H well in the Tui oil fields offshore Taranaki has advised that the well was at a measured depth of 3689 metres at 6.00AM NZDT today.

The Blow Out Preventer (BOP) was successfully installed and tested and the 13 3/8 inch casing shoe was drilled out. A 12 ¼ inch section was drilled vertically to 3,000 metres, at which point directional drilling commenced at an inclination of 45 degrees.

The 12 ¼ inch section is planned to be drilled to a TD of 4,100 metres.

Pateke-4H is a northern extension of the existing Pateke reservoir in the producing Tui area oil fields in PMP 38158, approximately 50 kilometres off the coast of Taranaki, New Zealand, in water depth of about 124 metres.

Drilling began on 10 February. The well is expected to take around two months to drill to a planned total measured depth of 5,361 metres, including a 1,271 metre horizontal section.

In the event that commercial volumes are discovered the well will be completed and later tied into the existing Tui production facilities. Production of first oil would be in 2015.

New Zealand Oil & Gas has 27.5 per cent interest in Tui.

The other Tui joint venture partners are:
AWE Limited (via subsidiaries) (Operator) 57.5%
Pan Pacific Petroleum (via subsidiaries) 15.0%
