Development

Kristin is a field in the Norwegian Sea, a few kilometres southwest of the Åsgard field. The water depth is 370 metres. Kristin was discovered in 1997, and the plan for development and operation (PDO) was approved in 2001. The field is developed with four 4-slot subsea templates tied-back to a semi-submersible facility for processing. The production started in 2005. An amended PDO was approved in 2007. The Tyrihans and Maria fields are tied to the Kristin facility. A PDO for Kristin South, including development of the Kristin Q segment and Lavrans, was approved in 2022.

Reservoir

Kristin produces gas and condensate from Jurassic sandstone in the Garn, Ile and Tofte Formations. The reservoirs are at a depth of 4600 metres and initially had high pressure and high temperature (HPHT).

Recovery strategy

The field is produced by pressure depletion. Low pressure production was implemented in 2014.

Transport

The well stream is processed at the Kristin platform and the rich gas is sent via the Åsgard Transport System (ÅTS) to the Kårstø terminal, where NGL and condensate is extracted. Light oil separated out on Kristin is transferred to the Åsgard C facility for storage and export.

Status

Kristin production is in the tail phase. The Kristin South development is ongoing and comprises development of the Kristin Q segment and the Lavrans field. Expected production start-up is in 2024.
