(Hint place the design equations in a excel spread sheet so you can change the variables.) Produced Fluids: Liquid is 35 deg API oil with 1.05 specific gravity salt water. The specific gravity of the mixture, in proportion to the WOR is 0.95. Water/Oil Ratio (WOR) is 1.00 BW/BO. Maximum Production Rate = 500 BLPD (barrels of liquid per day) The produced mixture is an emulsion that has the viscosity characteristics of 20 deg API oil. Reservoir, Pressure, and Temperature Data: Pump Intake Pressure = 100 psi Required surface pressure = 25 psi The flowing friction of this liquid in the tubing is 0.011 psi/ft. Maximum pump depth = 5500 BHT = 150 deg F Surface temperature = 100 deg F Tubing and Pump Data: The tubing is 2 7/8 OD and the pump OD is limited to the same size. The pump will have a single lobe rotor. The pump eccentricity is 0.3125 The Stator Pitch/eccentricity ratio (Ps/e) = 40.00 The ratio r/2e=0.9 The overall stator length ratio (L/q/DP) = 0.12 inch/(BLPD/rpm)/psi Pump volumetric efficiency = 0.7 Pump overall mechanical efficiency = 0.8 The stator major diameter cannot be larger than 2.4.The stator major diameter cannot be larger than 2....
