PRODUCTION FROM THE FIELD

Status

Snøhvit production is in the plateau phase. It is limited by the capacity at the LNG processing facility at Melkøya, which has had a stable and robust performance during recent years. New production wells have been drilled since start-up. Gas production from three wells on the Askeladd deposit is planned to start in 2020. Work is ongoing to evaluate future compression solutions, as well as measures for reducing CO2.

Development

Snøhvit is a field in the central part of the Hammerfest Basin in the southern part of the Barents Sea. The water depth is 310-340 metres. Snøhvit was discovered in 1984, and the plan for development and operation (PDO) was approved in 2002. Snøhvit was the first field development in the Barents Sea. The field includes the Snøhvit, Albatross and Askeladd structures and has been developed in multiple phases. The development includes several subsea templates. Two well slots are used for CO2 injection. Production started in 2007. A PDO exemption for Snøhvit North was granted in 2015.

Reservoir

Snøhvit produces gas with condensate from Lower and Middle Jurassic sandstone in the Nordmela and Stø Formations. The reservoirs lie at a depth of 2,300 metres and have moderate to good quality. Development of a thin oil zone underlying the gas at the Snøhvit structure is not included in the PDO.

Recovery

The field is produced by pressure depletion.

Transport

The well stream, with natural gas, CO2, natural gas liquids (NGL) and condensate, is transported in a 160-kilometre pipeline to the liquid natural gas (LNG) processing facilities at Melkøya near Hammerfest. The CO2 is separated and returned to the field by pipeline for injection into the aquifer (Stø reservoir). LNG, liquid petroleum gas (LPG) and condensate are shipped to the market.
