Q4: Experiments were made on a bottom-hole crude oil sample taken from the North Grieve Field to determine the gas solubility and oil formation volume factor as a function of pressure. The initial reservoir pressure was recorded as 3,600 psia and reservoir temperature was 130F The following data were obtained from the measurements Pressure, psia Rs, scf/STB BO, bbl/STB 567 567 567 567 3600 3200 2800 2500 2400 1800 1200 600 200 554 436 337 223 143 1.310 1.317 1.325 1.333 1.310 1.263 1.210 1.140 1.070 At the end of the experiments, the API gravity of the oil was measured as 40. If the average specific gravity of the solution gas is 0.7, calculate a. Total formation volume factor at 3,200 psia by using Definition of Bt. b. Oil viscosity at 3,200 psia by using Beggs Correlations. c. Isothermal compressibility coefficient at 1,800 psia
