Ula
Ula is located in the southern part of the Norwegian sector of 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, all connected by bridges. Production started in 1986. Ula’s gas capacity was upgraded in 2008 with a new gas processing and injection module (UGU), which doubled the capacity. Ula processes hydrocarbons from the Tambar, Blane and Oda fields.
Ula is in the late tail-end phase. The plan is to cease production in 2028. Removal of the Ula facilities is expected in the years following 2028.
The resource estimate for Ula has tripled compared with the original PDO estimate.
Increased oil recovery
Since 1998, water-alternating gas injection (WAG) has helped increase recovery from Ula. The effect of WAG has made it possible to drill several new wells and extend the lifetime of the field.
