The North Sea Martin Linge field is an oil and gas discovery made in 1978, and was previously called Hild. The field is located 42 kilometres west of Oseberg, in 115 metres of water. Equinor became the operator of the field in March, 2018, and it came on stream on June 30, 2021.
The Martin Linge field development comprises a jacket-based integrated wellhead, production and accommodation platform and a permanently anchored oil storage vessel. When the field comes on stream, the gas will be transported through a new pipeline connecting the field to the existing pipeline going to St. Fergus, Scotland. The oil will be processed on the storage vessel and transported from the field in shuttle tankers.
Power from shore
The Martin Linge platform receives shore power via the world’s longest alternating-current sea cable measuring 162 kilometres from the onshore substation at Kollsnes north of Bergen to the platform.
Shore power will reduce CO2 emissions by 200 000 tonnes per year, corresponding to emissions from 100 000 cars. The field will also be operated from land and have a limited offshore staff.
The platform was connected to shore power in December 2018.
Major hook-up job
A comprehensive hook-up and completion job is currently being done at the field. Around 650 people are at work offshore at any time. As there are three shifts, close to 2000 people in total are involved in preparing the Martin Linge platform for production.
About the reservoir
The main reservoir is structurally complex and contains gas and condensate at high pressure and high temperature (HPHT). There are three reservoirs in Middle Jurassic sandstones in the Brent Group at a depth of 3700-4400 metres. Oil has also been found in the Frigg Formation of Eocene age. The main reservoir is located at a depth of 1750 metres and the reservoir quality is good.
The plan for development and operation of Martin Linge was submitted to the authorities in January 2012 and approved by the Norwegian parliament in June the same year. Martin Linge came on stream on June 30, 2021.
Equinor is the majority shareholder of Martin Linge (70%). Petoro (30%) is the only partner.
