The high-pressure and high-temperature gas condensate field located in Block 15/29a, in a water depth of 492ft (150m) approximately 100 miles (160km) from the Scottish coastline and 37 miles (60km) from the UK/Norway median line.
Chevron North Sea, a subsidiary of Chevron, operates the project with a 73.7% stake, with co-venturer ConocoPhillips (UK) having 26.3% sake.
Chevron Upstream Europe managing director Greta Lydecker said: "First gas at Alder represents a significant milestone for Chevron and highlights our commitment to investing and developing resources in the UK.
“Alder supports our goal of helping to maximize the economic recovery of the UK, adds significant production to our portfolio, and helps extend the field life of Britannia, an important asset to Chevron in the North Sea.”
The field is a single subsea well tied back to the existing ConocoPhillips-operated Britannia Platform, in which Chevron owns a 32.38% non-operated working interest.
Discovered in 1975, the field is estimated to produce 110 million cubic feet of natural gas and 14,000 barrels of condensate per day.
UK Oil and Gas Authority CEO Andy Samuel said: “Chevron’s application of innovative subsea technologies and use of the UK’s experienced supply chain is closely aligned to the Maximising Economic Recovery Strategy, adding reserves and extending the life of an existing asset.”
According to estimates, the Alder field contains approximately 4,820 million standard cubic metres (scm) of gas.
