Pateke-4H drilling update 8 April

Posted on 8 April 2014

At 06:00 this morning (NZST) the Pateke-4H remains at a measured depth of 4,083m BRT (below rotary table), and the 9 5/8 inch casing has been installed and cemented with the shoe at 3,669m BRT.

The 8 1/2 inch drilling assembly is being run in hole and preparations are being made to drill out the shoe following which the well will be drilled horizontally through the F10 reservoir to a planned total measured depth of 5,361m BRT.

The Kapuni F10 sandstone objective has already been intersected as expected with oil shows and real time logging measurements indicating the likely presence of an oil bearing reservoir. The operator describes this as “very encouraging”, however, the commercial significance of the oil shows will not be clear until the horizontal drilling has been completed.

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.

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%
