PGE 362 Homework 5 Solution Due at the start of lecture on March 9. (1) (+2 pts) 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 = = = = VLP 0 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 0 1000 2000 3000 4000 5000 Oil Rate (BPD) Pwf (psi) 2 3/8" 2 7/8" 3 1/2" IPR max rates

(2) (+3 pts) 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 = = = = = = Gas IPR 0 500 1000 1500 2000 2500 3000 3500 4000 0 1000 2000 3000 4000 5000 6000 Gas Rate (MScf/Day) Pwf (psig) Pe = 4000 psi Pe = 2000 psi
(3) (+3 pts) 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. If not specified below the PPS fluid properties are the default variables. Oil = 35 deg API
