Unformatted text preview: PGE 312 – Physical and Chemical Behavior of Petroleum Fluids I Homework 9, Fall 2007 Problem 9-1 The given data is plotted and then a line of best fit is drawn through the pressure and GOR data. This is shown in the figure below: From the figure, Bubble Point Pressure = 2,000psia GOR = 520 scf/STB From Fig. 9-3, the correction for stock tank vent gas is 80scf/STB Therefore, R sb = 520 + 80 = 600 scf/STB Therefore, calculating the errors in P b and R s , % 692 . 3 100 623 623 600 % 734 . 3 100 2000 2000 1928 s b R in Error P in Error Problem 11-1 Using the given information, From Fig. 11-1, P b = 3,400 psia Problem 11-3 The following table is generated from Figure 11-1 by using the provided data.
