ABSTRACT:
A counterbalanced, long stroke pumping system provided with a composite material lifting string is conformed for optimum separation between the frequency spectra entailed in the pump drive and the fundamental resonances of the string. This separation allows for an expanded control bandpass within which an adaptive control system may be rendered operative to adjust stroke mechanics to meet pump-off conditions or other pumping anomalies.
