**Steam Assisted Gravity Drainage**

An investigative analysis into the fouling issues encountered during steam assisted gravity drainage operations

Steam assisted gravity drainage (SAGD) is a type thermal oil recovery process that is proving to be a leading commercial technology for the recovery of bitumen, similar to those contained in the Athabasca oil sands deposit. This unconventional oil recovery process demands high water usage, which necessitates the recycle of produced water from the reservoir. As such, the purity of the recycled water is of critical importance to the fouling of the various equipments such as heat exchangers and pipes used during SAGD. This investigative report will attempt to analyze the method to which the water which is produced alongside the oil can be purified, ultimately resulting in lower fouling rates of downstream equipment.
