The Cenovus Foster Creek facility is a 30,000 bbl/day steam assisted gravity drainage (SAGD) heavy oil project. Following successful work for Cenovus at their Christina Lake SAGD operation, Ausenco was awarded specialty EPCM services at Foster Creek.
Ausenco provided on-going design for the larger projects and support for field and operations-driven work. Experienced Ausenco personnel were able to provide rapid support at short notice for multiple projects related to debottlenecking and heavy plant maintenance. As plant production can be impacted, Ausenco staff were available at all times to respond to Cenovus’ needs. Many high priority projects had a turn-around window of just a few days.
Several larger projects were also completed, including surface facilities for two salt cavern storage operations for the storage of diluent, bitumen and natural gas. At Salt Cavern 1, Ausenco was responsible for adding infrastructure to change the operation from the cavern washing phase to the storage phase.
This included the addition of facilities to independently operate a sales oil line and a diluent line for injection into and withdrawal from the storage cavern. At Salt Cavern 2, cavern washing facilities were installed, including pumps and tankage, as well as two water pipelines. All work performed by Ausenco at Foster Creek was undertaken in a complex plant environment under very tight time constraints without impeding commercial operation.
