Abstract
When conducting borehole operations, such as drilling, injection, or hydraulic fracturing, using a variable torque converter to reduce the torque force output of a constant speed engine or motor would enable a more efficient use of resources and lower costs due to less wear and tear on equipment. The fluid pump system at the borehole can utilize the variable torque converter, receiving operating commands from a control system, to reduce the torque delivered to the fluid pump to maintain operational parameters, such as a rate of change of load on the engine or motor, a maximum fluid pressure measured at the pump or downhole, or other operational parameters. The variable torque converter can be part of a transmission system, or be located before or after the transmission system. The variable torque converter can utilize torque oil or a magnetic system to control the torque force being delivered.
