A pump with a 2-in plunger is to be set at 6050 ft using a three-way taper consisting of 34 in, 7/8 in and 1-in rods (API No. 86) in 2 7/8-in tubing. The volumetric efficiency of the pump is 0.75. Assume fluid specific gravity of 0.83, pumping speed of 16.9 spm, stroke length of 54 in, and desired fluid production of 150 bbl/d.

1) Calculate the peak and minimum polished rod loads, the effective plunger stroke and the pump displacement.

2) Draw the theoretical Dynagraph.
