Question

The following data are available on a volumetric undersaturated-oil reservoir:

• p_i = 3,900 psi
• p_b = 3,200 psi
• b_oi = 1.58 bbl/STB

Production has started and reached the bubble point-pressure (3,200 psi). Determine the STOOIP,  N, and the fractional oil recovery at p_b. The oil produced, N_p, at p_b is 680.0 MSTB and the B_o at 3,200 psiis 1.61 bbl/STB.
