Calculated Result
168.8 bar

Bubble Point Pressure (Pb)

Bubble Point in PSI

2447.6 psia

Solution GOR (Oilfield)

561.5 SCF/STB

Temperature (°F)

176.0 °F

Calculation Breakdown

  1. Convert units to oilfield parametersRs = 100 * 5.615 = 561.5 SCF/STB, T = 176.0 °F
  2. Apply Standing's empirical correlation for saturated oilP_b = 18.2 * [ (561.5 / 0.7)^0.83 * 10^(0.00091*T - 0.0125*API) - 1.4 ] = 168.8 bar
