A pressure gauge at the top of an oil well 18,000 ft deep registers 2,000 psig. The bottom 4000-ft portion of the well is filled with oil (s = 0.70). The remainder of the well is filled with natural gas (T = 60oF, compressibility factor Z = 0.80, and s = 0.65, meaning that the molecular weight is 0.65 times that of air). Calculate the pressure (psig) at the oil/gas interface and at the bottom of the well.
