The steam assisted gravity drainage (SAGD) method of oil recovery requires the conservation and recirculation of water. To prevent boiler and other component fouling, the free oil concentration in the produced water must be less than 1 part per million before reuse. The TD-550 Oil in Water Analyzer is the perfect solution for effective, low cost grab sample analysis. For a deeper understanding of the SAGD process and how fluorescence measurement technology is applied, read the following article on oil measurement in SAGD water, which was first presented to the 2015 International Water Conference (IWC) in Orlando, Florida.
