Pumping Speed, Pump Capacity, and Fluid Correlatio...

This Excel workbook has spreadsheet pages to compute:

• The necessary sheaves to achieve a desired pumping speed. This includes the use of a jack shaft if necessary. A supplemental page shows a diagram of the gear box driven directly by the prime mover and through the use of a jack shaft. Belt speed is computed and the recommended limits are shown. This is discussed in Chapter 8.
• The pump output at the surface. This includes the effect of anchored (always recommended) and unanchored tubing. The pump slippage is also calculated and used to compute the pump efficiency. This shows the effects of plunger clearance and length, pumping speed, and fluid viscosity on pump performance. This page also shows the maximum volumes of liquid and gas that can be successfully separated by the traditional “poor boy” downhole gas-liquid separator or mud anchor assuming it is placed above the perforations. These topics are discussed in Chapters 6 and 10.
• Fluid correlations for liquid viscosity, solution gas-oil ratio, and oil formation volume factor for use on the other pages or for general information. The correlations are from Chapter 4.
