Process studies completed by Ausenco revealed that bitumen production constraints at MacKay River resulted from bottlenecks in the produced gas infrastructure within MR1 plant site and not at the pads or pipeline. As a result, Ausenco was commissioned to complete the engineering within the MR1 facility to reduce back pressure at the well pads. Ausenco prepared the design basis memorandum (DBM), engineering design specifications (EDS) and detailed engineering (DE) for the project.
Construction was completed during a scheduled plant maintenance shutdown. Within two weeks of plant re-start, production reached nameplate design capacity for the first time.
