Question- An oil well is producing 930 scf/STB of .742 specific gravity separator gas and 40.8 API stock-tank oil. Separator conditions are 100 psig and 90 degrees F. The well has just been completed; reservoir pressure is believed to be above bubble-point pressure. Estimate a value of solution gas-oil ratio for use at and above bubble-point pressure.
Solve the above problem and provide steps with explanation
