Question #1 An oil well produces under steady-state conditions. Assume that there is no skin effect in the well system. The drainage area is 40 acres, and the reservoir pressure is 5000 psi. Generate inflow performance relationship (IPR) curves for three permeability values of 1 md, 10 md, and 100 md, respectively. Obtain other variables from Appendix A. as attached file. Solution : # under steady-state conditions #pwf = flowing bottomhole pressure *1 acres=43560 ft^2. So as A=40 acres =1742400 ft^2. We need also, to find r by using the following Eq r(e)= A π = 1742400 3.14 =744.9 ft K P q 1 1000 157.2 2000 117.9 3000 78.6 4000 39.3 10 1000 1571.86 2000 1178.9 3000 785.93 4000 392.97 100 1000 15718.7 2000 11789.01 3000 7859.34 4000 3929.67

    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.

    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.
