Book excerpt: "An experimental study was conducted to quantify the phase behavior and physical properties of Alaskan North Slope stock tank and live crude oils. Measurement of molecular weight, gas-oil ratio, and constant composition expansion and differential liberation tests were conducted on these samples. Phase behavior and reservoir fluid properties of the live oil samples were modeled using the Peng-Robinson Equation-of-State (EOS). The Peng-Robinson EOS was tuned with experimental data to predict the phase behavior accurately. The results of the modeling yielded a satisfactory match with measured saturation pressure and solution gas-oil ratio. This tuned EOS can be incorporated into the compositional reservoir simulator for field scale simulations of Alaska North Slope. The phase envelope obtained from this tuned PR-EOS when combined with wax phase envelope can help to design the production PT pathway. The measured gas-oil ratio of the bottomhole samples was compared to the crude oil composition and showed that higher the composition of C5-C10 in crude oil, greater is the gas-oil ratio"--Leaf iii.
