Pateke-4H subsea tie-back underway

Posted on 6 March 2015

The Operator of the Tui oil fields in PMP 38158 has announced that the Pateke-4H subsea tie-back and installation project has commenced.

Pateke-4H was drilled horizontally to 4,772 metres last year. The Pateke structure is one of three producing in the Tui field offshore Taranaki, New Zealand. The 4H well accessed a lobe not being drained by the existing Pateke well.

On Thursday the DOF Subsea Diving Support Vessel, Skandi Singapore, arrived to commence the tie-back project.

The project involves installing subsea pipelines, manifolds and ancillary support equipment in water depths of about 124 metres to connect the Pateke-4H development well to the Tui field gathering system.

The subsea tie-back and installation project will coincide with a two week planned inspection and maintenance shut down of the FPSO, Umuroa. First production from Pateke-4H is expected in April.

New Zealand Oil & Gas has a 27.5 per cent interest in the Tui field. The Joint Venture partners are:

• AWE Limited (via subsidiaries) (Operator) 57.5%

• Pan Pacific Petroleum (via subsidiaries) 15%
