Rod Pump VE: 2017 #42

Problem 42. The volumetric efficiency of the lift system in Problem 41 above (19 bbl oil+ 188 bbl water) is closest to...

On 7 PRD 9, we see: PD = 0.1166(64)10(1.75^2) = 228 bpd (prior problem).
Volumetric Efficiency = (Produced Volume)/(Pump Displaced Volume) = 19 + 188 = 207 so:
VE = 207/228 = 91%.

    Can you post the solution to 2017 #44 or where to find it in the Guidebook. 12 WLT 3 does not work.

    It's easy if I remember right, just use the equation on 12 WLT 3: -0.234qB/(ct dpwf/dt)=0.234(200)1.3 / (2E-5(125/4*24) = 2,336,256 cf = 216,000. Does this check out with you?
