Alve is a small gas and condensate discovery 16 kilometres southwest of the Norne field in the Norwegian Sea.
The field was proven in 1990 and comprises the Garn, Not, Ile and Tilje formations with proven reserves lying in Garn and Not.
A maximum gas production of around 4 million cubic metres (scm) per day is expected from the field.
Gas reserves are estimated at 6.78 billion scm and 8.3 million barrels of oil equivalent of condensate.
Alve will be phased in via tie-back to the Norne field and production is scheduled to start in early 2009.
