Production boosted from Vigdis field
Published by Nicholas Woodroof,
The Vigdis subsea field has produced oil via the Snorre field for 24 years. When the field came onstream in 1997, it was expected to produce 200 million barrels. So far, it has produced twice as much, and based on new estimates the recoverable resources are 475 million barrels.
In December 2018 the licence partners – Petoro, Vår Energi, Idemitsu and Wintershall Dea as well as Equinor – decided to invest around NOK1.4 billion in the Vigdis Boosting project. This is a project for improved oil recovery (IOR), which includes a multiphase boosting station increasing production from existing wells. This pump came on stream in May.
Connected to the existing pipeline between Vigdis and Snorre A, the boosting station helps bring the well stream from the subsea field up to the platform. In addition, it reduces wellhead pressure, which also leads to higher oil recovery from the wells.
The contract for supplying the boosting system, including the template and trawl protection, was awarded to OneSubsea, with engineering in Bergen and assembly at Horsøy near Bergen.
The company cooperated with sub-suppliers in Western Norway, such as Framo Flatøy, which fabricated the pump, RadøyGruppen, which fabricated the subsea template, and Luster Mekaniske Industri, which supplied the pipelines.
In addition to the subsea boosting station, smaller modifications have been made to Snorre A, which receives the oil from Vigdis, and Snorre B, which supplies the new boosting station with power from a new umbilical supplied by Nexans. Wood has been the main supplier for the modifications and the marine operations have been carried out by Deep Ocean.
