Example 1.3 Compute the pump factor in units of barrels per stroke for a double-acting duplex pump having: 6.5-inch liners (dL) 2.5 inch rods (dr) 18-inch strokes (LS) and a volumetric efficiency of 90%. (EV)
7
Solution: The pump factor for a duplex pump can be determined using Equation 1.10
8
Thus: Pump Factor = 0.2052 bbl/stroke
Recall: There are 231 in.3 in an U. S. gallon and 42 U.S. gallons in a U.S. barrel. Thus converting to the desired field units yields: 1991 in.3/stroke * gal/231 in.3 * bbl/42 gal. = bbl/stroke. Thus: Pump Factor = bbl/stroke
9
Pump Factor = 3 * p/4 dL2 LS EV/(231 * 42)
10
Example: Pump Factor for Triplex Pump
11
Example: Pump Rate = Pump Factor * Strokes/min = 0.09442
= bbl/min = gal/min Pump Rate = 317 gal/min

What is the capacity of 10,000 ft of 5” OD, 19.50 lb/ft drillpipe?
Capacity = Area * Length Area = p/4 d2 = p/4 * = in2 Length = 10,000 ft = 120,000 in Capacity = *120,000 in3 /(231*42 in3 /bbl) Capacity = bbls
36
What is the displacement of 10,000 ft of 5” OD, 19.50 lb/ft drillpipe?
Capacity = Area * Length Area = p /4 (od2 - id2 ) = p /4 * ( ) = in2 Length = 10,000 ft = 120,000 in Displ. = * 120,000 in3 /(231 * 42 in3 /bbl) Displacement = ? Bbls Displ. = bbls
