PETE 2032 Homework – Chapter 11 First Assignment 11.1 Your recently completed well is producing 40.3 o API oil and 0.756 specific gravity gas at 1000 scf/STB. Producing gas-oil ratio has remained constant, so you believe reservoir pressure is above the bubble-point pressure of the reservoir oil. Estimate bubble-point pressure given that reservoir temperature is 205 o F. From Figure 11-1 p b = 3390 psia 11.2 Estimate values of solution gas-oil ratio for pressures below bubble-point pressure for the reservoir oil of Exercise 11-1. Start at a pressure of 3150 psig and decrease pressure in 500 psi increments to a final pressure of 150 psig. 11-5 Use ideal-solution principles to calculate the density at 14.696 psia and 60 o F of a hydrocarbon liquid of the following composition. Pressure, Psia R s Scf/STB 3165 920 2915 834 2665 749 2415 666 2165 585 1915 505 1665 428 1415 353 1165 280 915 211 665 145 415 84 165 30 Component Composition, Mole fraction Propane 0.025 i-Butane 0.325 n-Pentane 0.650 1.000
