Alve
The Alve gas and condensate field is developed as a subsea satellite field tied back to the Norne field's production vessel.
Alve was discovered in 1990. The find led to the discovery of the Norne oil and gas field which was proven i 1992 and brought on stream in 1997.
Output from Alve and other finds in the area will extend Norne's lifetime from 2016 to 2021.
Alve has been developed as a conventional subsea solution. Gas will be exported through the pipeline systems established at Norne.
Alve lies in production licence 159B, about 16 kilometres south-west of Norne. The field embraces the Garn, Not Ile and Tilje formations. The proven reserves lie in Garn and Not.
The quality of the reservoir at Alve is such that one well ensures good production. Expected maximum gas production is roughly four million cubic metres of gas per day.
Recoverable reserves are estimated to be 6,78 billion cubic metres of gas and 8.3 million barrels of condensate.
