PGE 362 Homework 5 Due at the start of lecture on March 9. (1) Please use the VLP graph you created for HWK 3 and place on it the IPR curve for the following well tests. Show on the graph the maximum theoretical flow rate for each tubing size. 1 1 2 2 500 STBO/Day 3,333 psi 750 STBO/Day 3,000 psi o wf o wf q p q p = = = = (2) Please prepare on the same graph a plot of pwf vs gas flow rate for the current conditions and for the future conditions when reservoir pressure has declined. g 180 deg F 0.67 current 4,000 psi with flow test of 1000 MScf/Day at 3500 psig future 2,000 psi e wf e T p q p p γ = = = = = = (3) Please prepare on the same graph a Vogel’s IPR for the current and future conditions if oil permeability is assumed to be a constant.

Unformatted text preview: the PPS fluid properties are the default variables. Oil = 35 deg API WOR = 0 Initial Tests: 2500 psi 300 STBO/Day at 1500 psi Future 1,500 psi o wf p q p p = = = = (4) Using the PPS “skin” module please make a table showing the perforating skin for each of the following perforating options. (a) The default settings except the reservoir thickness = the completion thickness and the damage permeability = the horizontal permeability. Compare shot densities of 2, 4, 8, and 12 spf and phasing of 0, 90, and 60 degrees for each shot density. (b) Repeat part (a) except change the perforation diameter to 0.35” and the length to 21.5”....

    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.
