Snøhvit Future Development Concepts for increased gas export capacity 2 nd Trondheim Gas Technology Conference 2-3 rd November 2011 Øystein Holt, Technology Manager 2011-11-02
Snøhvit A dream came true 2 2011-11-02
Snøhvit a pioneer project The first large-scale production facility for LNG in Norway and Europe The first offshore project in the Barents Sea The largest-ever industrial development in northern Norway New technology New markets New operation organisation 3 2011-11-02

Snøhvit Future Development The Snøhvit License is evaluating the basis for increased production Three alternatives are evaluated 1. Lifetime extension of LNG Train I 2. LNG Train II from 2018 3. Increased production from a gas processing facility and pipeline transport from Melkøya in 2022+ The pipeline case is evaluated by Gassco on behalf of the Snøhvit License 5 2011-11-02
