The Norwegian Petroleum Directorate (NPD) has given the licensees of Gullfaks Sør permission to start-up and operate a new subsea wet gas compressor and umbilicals on the Gullfaks Field in production license 050, the NPD said in a news release.

The Gullfaks project, operated by Statoil, is the second major seabed gas compression project that will be initiated, after the NPD granted consent for the startup of Åsgard subsea compression in July 2015.

"For Gullfaks, this gas compression means extended lifetime and an increase in the gas recovery rate from Gullfaks Sør Brent from 62 to 74 percent,” said Astri Fritsen, principal engineer for the NPD.

The compressor station and the umbilical installed on the seabed on Gullfaks will push the well stream from templates D, L, M, and N up, the release said. Production is scheduled to start no later than October.

In addition to accelerating gas production and extending the period when the gas capacity on the Gullfaks C facility is utilized, the new infrastructure will increase the gas and condensate reserves from the reservoirs on Gullfaks Sør Brent and Rimfaks Brent, NPD said in the release. This also enables the realization of additional resources in the greater Gullfaks area.
