Njord to switch to low-pressure production

Offshore staff

STAVANGER, Norway – The Njord partners have opted to implement low-pressure production at the Norwegian Sea field. This, combined with other measures, should extend Njord’s lifespan through 2020.

Reservoir pressure is falling and the field is now in its tail-end phase. By lowering the pressure on the first and second-stage separators, operator Statoil says it should be able to increase production from individual wells and to maintain that output production over an extended period.

“Owing to the complexity of the Njord reservoir the recovery rate of proven resources is currently roughly 23%,” said Ivar Aasheim, Statoil’s head of NCS field development. “The aim is to increase the recovery rate to 30%.”

The Njord northwest flank project is also under way, 6 km (3.7 mi) northwest of the Njord platform. This involves drilling two new long-distance wells directly from and tied back to the platform. In addition, production from the fasttrack Hyme development will be processed via Njord.

Njord’s low-pressure production project should lift volumes by around 18.5 MMboe. Statoil puts the associated investments at roughly NOK 500 million ($91.5 million).

Reinertsen won the contracts both for Njord low-pressure production modification and the Hyme topside module. The contract for compressor procurement and installation was awarded this March to GE Oil & Gas.

Work will be executed during fall 2012. Low-pressure production on Njord is scheduled to start during 4Q 2012.
