Snohvit LNG Project

From Global Energy Monitor

The Snøhvit LNG Project is an offshore LNG project with Carbon Capture and Storage(CCS) in the southern part Barents Sea off the coast of Norway which has been developed by Equinor (formerly known as Statoil).[1][2]

Location

The map below shows the location of the field, in the central part of the Hammerfest Basin in the southern part of the Barents Sea.[2]

Background

Snøhvit was discovered in 1984 and its and the plan for development and operation (PDO) was approved in 2002.[2] Three gas fields --the Snohvit, Askeladd and Albatross fields-- are included in the project. The Snøhvit and Albatross wells came on stream in 2007, with the Askeladd development expected to start production "after 2020" according to Equinor.[3]

Snøhvit LNG Project consists of nine wells, eight for production and one for injecting carbon dioxide.[3]

Gas from Snøhvit, Askeladd and Albatros is transported through a 160-kilometre pipeline to Hammerfest LNG Snohvit Terminal.[2] Carbon dioxide is returned to the field by pipeline for injection into the Stø reservoir in a process known as Carbon Capture and Storage (CCS).

Phase 2 (Askeladd)

In 2018, Equinor announced that it alongside partners in the project had "decided to invest just over NOK 5 billion in the further development of the Snøhvit field in the Barents Sea."[4] Askeladd, also known as Snøhvit Phase 2, was expected to supply 21 billion cubic metres of gas and two million cubic metres of condensate to Hammerfest LNG Snohvit Terminal. The Petroleum Safety Authority (PSA) gave Equinor its consent for Askeladd Phase 1 facilities in September 2020.[5] At that time, it was expected that production from Askeladd would begin before 2020 year end, however, a fire at the Hammerfest LNG Snohvit Terminal led the the Snøhvit, Albatross and Askeladd fields to be shut-in.[6]

Carbon Capture and Storage (CCS)

Statoil states that the gas which is piped from the Snøhvit field to Melkøya processing plant outside Hammerfest contains 5-8% carbon dioxide. The C02 is separated from the natural gas, piped back via a 153km pipeline to the "edge of the Snøhvit reservoir" and reinjected at a depth of 2600 metres beneath the seabed. Statoil states that "at full capacity on Snøhvit, 700,000 tonnes of CO2 will be stored per year". The company also states that "a shale cap which lies above the sandstone will seal the reservoir and ensure that the CO2 stays underground without leaking to the surface."[7]

Following a fire at the Hammerfest LNG facility at Melkøya on 28 September, the operator, Equinor, has advised that it may take until 1 October 2021 for operations to restart. As a consequence, the Snøhvit, Albatross and Askeladd fields have been shut-in. Neptune's losses of revenue from the Snøhvit Unit will be recovered through business interruption insurance, claims for which are effective 60 days after the incident.
