2 Separator Pressure = 30psig = 30+14.7 = 44.7psia Separator Temperature = 120 o F Separator gas gravity = 0.888 Stock tank oil gravity = 36.1 o API Laboratory solution gas-oil ratio = 318 scf/STB Solution: Plotting the production history against cumulative oil production, we can deduce the solution gas-oil ratio as the producing gas-oil ratio at bubble point. The plot is shown below Therefore, the solution gas-oil ratio is 315scf/STB.
3 Adjusting the solution gas-oil ratio for vented stock tank gas by using stock tank gas-oil ratio correlation in Fig. 9-3, we get R sb = 315 + 23 = 338 scf/STB. The estimated solution gas-oil ratio can be compared with the laboratory value as follows: Since the percentage error is less than 10%, we have obtained a very good estimate of the solution gas- oil ratio. Problem 9-3 Given: Reservoir pressure, psia Cumulative oil production, MSTB 3122 110 2982 370 1830 1050 1275 1400 965 3060 1095 3160 933 3360 495 4620 Bubble point pressure measured in the lab = 1441psig = 1445.7psia.
