1 PGE 312 - SPRING 2009 Physical and Chemical Behavior of Petroleum Fluids I Test #2, 50 Minutes Closed Book Note: It will be in your best interest to attempt all the questions. Please budget your time accordingly. Problem 1 (32 points) Figure 1 shows the Pressure-Temperature (P-T) diagrams for four petroleum fluids designated as A, B, F and D, relative to the initial reservoir pressure and temperature (P res , T res ). Table 1 shows the compositions of the four fluids arranged in no particular order. You are requested to match each fluid composition (Fluid 1, Fluid 2, Fluid 3 and Fluid 4) to the appropriate P-T diagram and then classify the petroleum fluid. Present your result by filling out Table 2. Figure 1. P-T diagrams for four petroleum fluids. C is the critical point and T res and P res are the reservoir temperature and the initial reservoir pressure, respectively.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
