very difficult question

Asalamu alikum

Can someone solve this question ....

1.The following data are taken from an oil field that had no original gas cap and no water drive:

Oil pore volume of reservoir = 75 MM cu.ft.
Solubility of gas in crude = 0.42 SCF/STB/psi
Initial bottom-hole pressure = 3500 psia
Bottom-hole temperature = 140oF
Bubble-point pressure of the reservoir = 2400 psia
Formation volume factor at 3500 psia = 1.333 bbl/STB
Compressibility factor of the gas at 1500 psia and 140oF = 0.95
Oil produced when pressure is 1500 psia = 1.0 MM STB
Net cumulative produced GOR = 2800 SCF/STB

(a) Calculate the initial STB of oil in the reservoir.
(b) Calculate the initial SCF of gas in the reservoir.
(c) Calculate the initial dissolved GOR of the reservoir.
(d) Calculate the SCF of gas remaining in the reservoir at 1500 psia.
(e) Calculate the SCF of free gas in the reservoir at 1500 psia.
(f) Calculate the gas volume factor of the escaped gas at 1500 psia at standard conditions of 14.7 psia and 60oF.
(g) Calculate the reservoir volume of the free gas at 1500 psia.
(h) Calculate the total reservoir GOR at 1500 psia.
(i) Calculate the dissolved GOR at 1500 psia.
(j) Calculate the liquid volume factor of the oil at 1500 psia.
(k) Calculate the total, or two-phase oil volume factor of the oil and its initial complement of dissolved gas at 1500 psia.
