Statoil has started its fast-track project for improved oil recovery from Gullfaks South (GSO) in the North Sea.
The company aims to increase output from the area by an estimated 65 million barrels of oil equivalent.
Production was started three years ago in the Gullfaks region after the project was approved.
Statoil said NOK 9 billion has been invested.
Arild Dybvig, vice president for fast-track projects in Development & Production Norway, said:“GSO demonstrates how we can increase recovery and profitability by use of standardised, simplified development solutions tied to existing infrastructure.”
GSO represents a move by the Norwegian company to focus on improved recovery, standardisation and industrialisation in line with Statoil’s continuous effort of maximising value creation on the Norwegian continental shelf.
This project is part of Statoil’s fast-track portfolio, but it has a larger and more complex subsea scope than ordinary developments of this kind.
The project also involved 370 drilling rig days and the drilling programme will continue through the first quarter of 2016.
GSO covers two subsea templates, four production wells, two gas injectors, a gas injection pipeline and a total of three production tubings, in addition to umbilicals and power cables for pipeline heating.
There are a total of 22 subsea tie-ins.
