Equinor has secured approval from the Norwegian Petroleum Directorate (NPD) for start-up of the Trestakk field in the Norwegian Sea.

Trestakk is located in production licence PL091. Equinor operates the licence with 59.1% stake, with ExxonMobil (33%) and Vår Energi (7.9%) as partners.

With permission now secured, Equinor plans to commence production at Trestakk in May 2019. The number of producing fields on the Norwegian shelf has now increased to 85.

According to Equinor, Trestakk hosts around 10.7 million standard cubic metres of oil (67 million barrels) and 1.4 billion cubic metres of gas in total recoverable volumes.

Situated nearly 25km southeast of the Åsgard field, the Trestakk field was discovered in 1986. The water depth in the region is around 300m.

The offshore development of Trestakk includes a subsea template comprising four well slots and one satellite well. Total investments in the development of the field are expected to amount to NOK4.8bn ($550m).The plan for development and operation (PDO) of the field was approved in 2017.

Once recovered, the wellstream will be transferred through a 12-inch production pipeline to the Åsgard A facility for processing.

Equinor plans to produce the Trestakk reserves with pressure support in the form of gas injection. The life expectancy of the field is expected to be around 13 years.
