Kristin is a gas condensate field in the Norwegian Sea. The field is developed with four subsea templates tied back to a semi-submersible facility for processing, Kristin Semi. The water depth in the area is about 370 metres.
Provision has been made for tie-in and processing of other deposits in the Kristin area.
**Tyrihans Oil and Gas Field** is tied back to Kristin and started production in 2009.
The Maria Oil Field is also to be tied back to Kristen
The wellstream is processed at Kristin and the gas is transported in a pipeline to Åsgard Transport and further to Karsto Gas Processing Plant.
Light oil is transferred to Åsgard for storage and export. Condensate from Kristin is sold as oil (Halten Blend).

- Development of the Lavrans and Kristin Q discoveries, utilising a new subsea template which is tied into the Kristin platform

The reservoirs are in Jurassic sandstones of the Garn, Ile and Tofte Formations and contain gas and condensate under very high pressure and temperatures. The reservoirs lie at a depth of 4 600 metres. The reservoir quality is good, but low permeability in the Garn Formation and flow barriers in the Ile and Tofte Formations contribute to a rapid decline in reservoir pressure during production.
