This paper will present a summary of jet pump theory and performance, and an algorithm for applying jet pumps to the wide range of conditions encountered in oil wells. Nozzle and throat sizes available from National Production Systems, Kobe, Inc., and Guiberson Hydraulic Pumping Systems, the three major suppliers of oilfield jet pumps, will be presented. Appendices will include hand-held calculator application programs for a TI-59 and an HP-41C. Comparisons between the predictions from the calculator programs and the sophisticated programs used by the pump manufacturers as well as actual well data, will demonstrate the applicability and limitations of the techniques presented in this paper. The discussion will include Potential sources of error and the sensitivity of the calculations to uncertainties in the well data.
