Project Profile

Value: US$585 million  
Location: North Sea, 200 km northwest of Bergen, west Norway
Recoverable reserves: Crude oil 1.529 Billion barrels and Gas 230 Billion cubic feet
Water depth: 300-350 metres
Production start-up: 4Q 2022 (Expansion programme)

The Snorre field is located at a water depth between 300-350 metres in the North Sea, 200km northwest of Bergen in west Norway. This offshore oil field was discovered in 1979 and is the sixth largest oil field in Norway. Field development began in 1988, and production began in 1992 through the use of an offshore production facility known as the Snorre TLP (Tension Leg Platform). The field development started from the southern region, followed by the northern region where the Snorre B Platform, a semi-submersible production vessel, was installed in 2001. Current production at Snorre relies on these 2 platforms and sub-sea production facilities.

The oil and gas were found at the Snorre field, beneath the seafloor at a depth of 2,500-3,000 metres, is within the Triassic and Jurassic period stratum (approximately 200 million years old). We have drilled more than 60 wells in the Snorre field. These wells include production, and water/gas injection wells for the optimum recovery of natural resources. The uses of state-of-the-art technologies, such as horizontal drilling, have been adopted to achieve efficient recovery and maximise production.
