a) Given the following rock and fluid data (Table 1), determine the change in transmissibility to gas with 0.61 gravity and to oil when pressure declines from 2,014.7 to 1,614.7 psia. b) What do you infer from the transmissibility changes in gas and oil? Given the oil properties and gridblock dimensions are as follow: Ax = Ay = 100 ft, Az = 10 ft, kx = 4.2 md, Mo = 3.0 cp, co = 1.6 x 10-6 psi-¹, T = 580°R, Psc = 14.7 psia, Tsc = 520ºR, and Bo= 1.22 RB/STB, where Bo is reported at 1,014.7 psia and reservoir temperature.
