Pateke-Tui Area tieback goes onstream offshore New Zealand

Offshore staff

NORTH SYDNEY, Australia – AWE has delivered first oil from the Pateke-4H development well in the PMP 38158 concession, 50 km (31 mi) offshore Taranaki, New Zealand.

The well is connected via a subsea tieback to the FPSO Umuroa serving the Tui Area oil fields.

Flow testing is under way to determine the optimal well settings. The well initially achieved an unstabilized flow rate of 34,000 b/d at 67% choke with a 48% water cut, in line with field modeling.

AWE plans to test various facility parameters, including choke settings, before establishing a much lower stabilized flow rate for long-term production. Over time oil output will likely decline as the water cut increases in the well.

The project involved installation of 1,312 m (4,304 ft) of flexible flowline, a gas lift umbilical and production manifold, integrated controls and ancillary equipment in water depths of about 124 m (407 ft).
