Q4. Calculate the gas-to-oil ratio, stock-tank oil gravity and formation-volume factor which will result from a two-stage separation of the hydrocarbon mixture below. Use separator conditions of 76 F and 100 psig. Assume that the mixture is a liquid at its bubble point at reservoir conditions of 2,695 psig, 220"Fand Por = 46,04 lb/cu ft.
