Gorm Field Last updated February 24, 2026 Natural gas and oilfield in the North Sea
Gorm natural gas and oilfield in the Danish Sector of the North Sea . It was discovered in 1971 and is the largest oilfield exploited by Denmark . [ 1] The production infrastructure consists of five bridge-linked platforms [ 2] and is operated by BlueNord. The facilities include two wellhead platforms and several processing platforms. The Rolf Dagmar
Reservoir The reservoir properties of the Gorm field are as shown.

In 2014 there were 32 oil production wells, one gas injection well, and 14 water injection wells. [ 4]
Pipelines A number of pipelines transport fluids to and from the Gorm field. The Skjold, Rolf and Dagmar fields are satellites of Gorn

Production The original design production rate for the process facilities on Gorm C was 60,000 barrels of oil per day (bopd). The design gas injection rate was 84 mmscfd (million standard cubic feet per day). The pumping platform Gorm C had a design throughput of 90,000 bopd. [ 3]
The production strategy is to maintain reservoir pressure through water injection. [ 4]
The production data for the Gorm field is shown in the following table. Production and injection numbers are cumulative rates up to 1 January 2014. About 400 barrels per day (64 m 3 /d) of crude oil from the nearby Rolf oil field are processed on the Gorm platforms. [ 6]

In 2014 the annual production was 6.3 million barrels of oil and 3,677 million standard cubic feet of gas (104 million m3 gas). [ 5]
Incidents An oil leak occurred in the field on 2 March 2011. [ 7] [ 6]
Dagmar and Rolf fields The Dagmar and Rolf fields are satellites to the Gorm installations. The characteristics of the fields are as follows.
