North Sea · Oil · Producing · Operator Aker BP ASA

Ula is an oil field in the North Sea operated by Aker BP ASA, discovered in 1976 by wellbore 7/12-2. The Norwegian Offshore Directorate lists it as producing.

In the 12 months reported through August 2026 it sold 0.26 million Sm³ of oil equivalents (0.24 million Sm³ of oil, 0 billion Sm³ of gas), down 10% on the 12 months before.

Since October 1986 it has reported 86.9 million Sm³ of oil equivalents: 77.4 million Sm³ of oil and 3.9 billion Sm³ of gas.

2 companies hold it; the largest share is Aker BP ASA with 80%.

About the field

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Development: Ula is a field in the southern part of the Norwegian sector in the North Sea. The water depth is 70 metres. Ula was discovered in 1976, and the plan for development and operation (PDO) was approved in 1980. The development consists of three facilities for production, drilling and accommodation, which are connected by bridges. The production started in 1986. The gas capacity at Ula was upgraded in 2008 with a new gas processing and gas injection module (UGU) that doubled the capacity. A PDO exemption for the Triassic reservoir was granted in 2015. Ula is the processing facility for the Tambar, Blane and Oda fields.
Reservoir: Ula produces oil mainly from sandstone in the Upper Jurassic Ula Formation. The reservoir is at a depth of 3345 metres and consists of three units. There is also production from part of the underlying Triassic reservoir at a depth of 3450 metres. This is a tight sandstone reservoir with low effective permeability.
Recovery strategy: Oil was initially recovered by pressure depletion, but after some years water injection was implemented to improve recovery. Water alternating gas injection (WAG) started in 1998. The WAG program has been extended with gas from the tied-in Tambar, Blane and Oda fields. Gas lift is used in some of the wells.
Transport: The oil is transported by pipeline via the Ekofisk field to Teesside in the UK. All gas is reinjected into the reservoir to increase oil recovery.
Status: Production from Ula is in the late life phase. Gas supply for WAG is challenging and the production is declining. It is planned to cease production in 2028. The resource estimates on Ula are more than three times higher than the original PDO estimates.
