Dean Stark Extractions done at Bureau Veritas assist geologists in determining the value and process-ability of their lease

The Dean and Stark test seems like it was designed with the Oil Sands in mind as it is ideally suited to quantify the three key fractions of Oil (Bitumen), Solids and Water in Cores, Froths, Tailings, and other materials within the Oil Sands industry. The apparatus is a continuous extraction or dewatering device that uses the fundamentals of distillation to continuously extract mixed-matrix samples with a clean solvent so they can be isolated and quantified or further analyzed.

Our customers use Dean and Stark:

  • Data from core samples to determine Fluid Saturation of their core material which assists geologists in determining the value and process-ability of their lease
  • Data for tailings characterizations to report volumes to regulators (tailings characterization)
  • For oil sands froth and well emulsions to separate water and oil mixture allowing additional testing such as compositional assays on the recovered "cleaned" oil
