Crude Oil: The physical and chemical properties of stock tank crude/condensate must be measured as the information is essential for crude valuation, fluid processing, refineries, transportation and to assess flow assurance issues. A detailed crude oil assay is performed to determine boiling range distribution and cut point yields of stock tank liquids up to 575°C. Further chemical analysis is performed on the distillate fractions/residues and the results used for crude oil trading and refining purposes.
