Development

Alve is a field in the Norwegian Sea, 16 kilometres southwest of the Norne field. The water depth is 370 metres. Alve was discovered in 1990, and the plan for development and operation (PDO) was approved in 2007. The development concept is a standard subsea template with four production wells. Alve is tied to the Norne production, storage and offloading vessel (FPSO) by a pipeline. The production started in 2009. An exemption from a PDO was granted for the development of the discovery 6507/3-8 Andvare in 2023.

Reservoir

Alve produces oil and gas from sandstone of Early and Middle Jurassic age in the Tilje, Not and Garn Formations. The reservoir is at a depth of 3600 metres and has moderate to good quality.

Recovery strategy

The field is produced by pressure depletion.

Transport

The oil is offloaded from the Norne FPSO and the gas is transported via the Norne pipeline to the Åsgard Transport System (ÅTS) and further to the Kårstø terminal for export.

Status

Production from Alve is constrained by the commercial agreement with the Norne licence and the gas handling capacity on the Norne FPSO. Excess capacity on the FPSO in recent years has made it possible to process larger volumes of gas from Alve. The long-term activity on the field is to optimise production. Andvare will be drilled and produced from a well slot available on Norne and is expected to start production in 2025.
