Equinor and its partners have decided to develop Phase 1 of the Kristin South project in the Norwegian Sea.

The first phase involves the development of two discoveries Lavrans and Kristin Q and is estimated to cost approximately $753.43m (Nkr6.5bn).

The Kristin Q discovery is a part of the Kristin field, which started production in 2005. The Lavrans is located 10km south-east of the Kristin field.

The Lavrans discovery is said to hold a large gas volume while Kristin Q is expected to be a high-pressure, high-temperature reservoir.

Equinor plans to develop both discoveries via tieback to the Kristin platform.

Although the technical life of the Kristin platform is expected to end in 2034, it can be extended further to 2042, Equinor said.

The Kristin South phase 1 project is expected to produce 6.2GSm³ of gas and 1.9MSm³ of oil, which is a total of 58.2 million barrels of oil equivalent.

Equinor projects, drilling, and procurement executive vice-president Arne Sigve Nylund said: “The decision to develop the Kristin South area will generate substantial value for society and the owners. We exploit the resources and the existing infrastructure in a favourable way while contributing to further development of the Norwegian Sea.”

The partners plan to install a subsea template at the Lavrans discovery. For the Kristin Q discovery, the firms plan to reuse an already installed subsea template.

A total of five wells are planned to be drilled, including four at Lavrans and the other well at Kristin Q.

Production from two wells at Lavrans and the one well at Kristin Q is planned to start in 2024.

The remaining two wells at the Lavrans discovery are scheduled to start production in 2025.

Equinor is the operator of the Kristin field with a 54.8% stake. Other partners in the field are Petoro (22.5%), Vår Energi (16.6%), and Total E&P Norge (6%).

A plan for development and operation (PDO) for the Kristin South project phase 1 has been submitted to the Norwegian minister of petroleum and energy by the partners.

Aker Solutions will provide subsea production facilities of the Kristin South project phase one whereas TechnipFMC will be responsible for pipeline fabrication, pipelaying, and subsea installation services.
