Abstract

See full text

An electro-hydraulic high-pressure oilfield pumping system includes a fracturing (frac) pump and a primary electric motor as a prime mover that delivers power to the frac pump. The primary electric motor may be a constant speed AC (alternating current) motor. A hydraulic starting motor may rotate a shaft of the primary electric motor to achieve or approximate its fixed rated speed before the primary electric motor is energized. A slow frac hydraulic motor may rotate the shaft of the primary electric motor as a passive torque transmission device that delivers power in a downstream direction through a transmission and to the frac pump.
