Calculates critical stresses at the top and bottom of each rod section. Calculates monthly power bill, and electricity cost per barrel of fluid and per barrel of oil using efficiency curves for NEMA D or Ultra High Slip motors. Calculates gross pump stroke, pump volumetric efficiency, overall system efficiency, peak torque and gearbox loading for existing and balanced conditions, and the counterbalance you need to balance the unit. The report also shows the difference between balancing the unit for minimum gearbox torque versus minimum energy usage. From the downhole pump card it can calculate fluid load, fluid level, pump intake pressure, net stroke, and pump fillage.
Plots surface and downhole dynamometer cards and gearbox torque plots.
Also, it can print a single page output that includes all the quantities calculated by the program, including the dynamometer and torque plots. You can also digitize analog dynamometer card plots with Summagraphics or compatible graphics tablets. Theta Enterprises makes its dynamometer file format available to anyone who wants it. You can customize the program by entering your company name, electricity cost, and custom rod grades and measured pumping unit dimensions to avoid having to type them in for each new case. You can also enter rod grade information for any steel sucker rod types that are not already in the program's database.
