This constitutes phase 1 of the Kristin South project, and the plan for development and operation (PDO) will now be submitted to the minister of petroleum and energy. Capital expenditures for this first phase will total about NOK6.5 billion.
Production from Lavrans and Kristin Q will be tied into the Kristin platform. A subsea template will be installed at Lavrans, while at Kristin Q an already installed subsea template will be reused. A total of five wells are planned to be drilled, four at Lavrans and one at Kristin Q.
The Kristin field was put on-stream in 2005. The technical life of the Kristin platform is estimated to end in 2034, with possibilities of further life extension to 2042.
The Lavrans discovery was discovered in 1995. The discovery has a large gas volume, and a high value potential. Lavrans is a complex reservoir and the production qualities are uncertain. The Lavrans wells are therefore designed to reduce this uncertainty by having long horizontal production zones in the reservoir. Kristin Q is located in the southern part of the Kristin field. Like the rest of the Kristin field, Kristin Q is a high-pressure, high-temperature reservoir. Lavrans and Kristin Q will be developed as one project with a shared pipeline to the Kristin platform.
The expected production in phase 1 of the Kristin South project is estimated at 6.2 GSm3 of gas and 1.9 MSm3 of oil (a total of 58.2 million boe).
The plan for development and operation also includes a description of possible future phases of the Kristin South project, including a possible next phase of Lavrans, as well as possible development of the Erlend and Ragnfrid discoveries.
The CO2 intensity for extraction and production of Kristin South phase 1 is less than 1 kg of CO2 per barrel of oil equivalent. The emissions will mainly be generated from the project’s drilling activities.
Lavrans and Kristin Q will be operated by the Kristin organisation, which is located at Stjørdal in Mid-Norway. Production from the first three wells, two at Lavrans and one at Kristin Q, is scheduled to start in 2024. Production start for the two last wells at Lavrans is scheduled for 2025.
Aker Solutions has been awarded the contract for subsea production facilities. The contract has an estimated value of about NOK 1 billion, and includes subsea template fabrication at Aker Solutions in Sandnessjøen, deliveries from Tranby and Egersund in Norway, as well as from Brazil, the UK, and Malaysia. The supplier estimates that more than 200 person-years of employment will be generated by the project in Norway.
TechnipFMC has been awarded the contract for fabrication of pipeline, pipelaying and subsea installation services. The project will be managed from Technip FMC’s Oslo operations centre. The pipelines will be fabricated at the spool base in Orkanger. TechnipFMC will also deliver the umbilical, which will be produced in the UK. The total contract value is estimated at about NOK1 billion.
Aibel has been awarded the contract for engineering, procurement, construction and installation (EPCI) for the modification of the Kristin platform. Worth about NOK190 million the contract will generate about 80 person-years of employment for Aibel in the engineering period. The work will take place in Haugesund.
The contracts are subject to government approval of the plan for development and operation.
In connection with the investment decision and plan for development and operation for the Kristin South project, the partners have signed an agreement to extend the area for the partnership Haltenbanken West Unit, making the discoveries Lavrans, Erlend and Ragnfrid in addition to the Kristin field part of Haltenbanken Vest Unit as of 1 June 2021.
Haltenbanken Vest Unit now comprises production licenses 134 D, 199 and 257.
