On a previous project phase, Vista successfully completed work for a client wishing to triple the capacity of Steam Assisted Gravity Drainage (SAGD) emulsion processing from 20,000 barrels per day (BPD) to 60,000 BPD bitumen. On this two-phased project, the client subsequently engaged Vista to perform the engineering and procurement for a further expansion of the SAGD facility from 60,000 BPD to 120,000 BPD. Vista’s work centered on expanding the areas of steam generation, oil treating, produced water de-oiling, softening and recycle as well as major utility expansions.
The original plant design made no allowance for expansion, which resulted in significant layout and infrastructure challenges, and highly complex debottleneck engineering in the first expansion project. These issues were compounded with this second expansion; however, Vista was able to meet these challenges to the satisfaction of the client and we continue to work with them on other significant projects.
