Variable torque converter for borehole operations

A well system, comprising:

• surface equipment for performing a borehole operation for a borehole formed through a subterranean formation, wherein the borehole is undergoing the borehole operation;
• and
• a fluid pump system located to deliver a fluid to the borehole, the fluid pump system including:
• a constant speed power mechanism capable of operating at a constant speed and generating a torque;
• a fluid pump capable of pumping the fluid suitable for the borehole operation, wherein the torque generated by the constant speed power mechanism is utilized by the fluid pump;
• a control system capable of collecting input parameters from electronically coupled systems and communicating output parameters to the electronically coupled systems;
• a machine learning system capable of receiving the input parameters from the control system and communicating the output parameters to the control system, wherein the machine learning system modifies the output parameters using learning parameters from previous borehole operations at the borehole, borehole operations from other boreholes, or lab experimentation;
• and
• a variable torque converter capable of reducing the torque generated by the constant speed power mechanism prior to the torque being utilized by the fluid pump utilizing a torque oil, and the variable torque converter, the constant speed power mechanism, and the fluid pump are the electronically coupled systems.

A method of performing a fluid pumping operation at a borehole, comprising:

• locating a variable torque converter between a constant speed power mechanism and a fluid pump;
• determining an event for the fluid pump, wherein the event is determined by a borehole operation plan or received sensor data;
• generating an operating command from the event using a machine learning system capable of receiving input parameters from a control system and communicating output parameters to the control system, wherein the machine learning system utilizes learning parameters from previous borehole operations at the borehole, borehole operations from other boreholes, or lab experimentation;
• and
• adjusting a torque delivered to the fluid pump by the constant speed power mechanism using the variable torque converter as directed by the operating command, wherein the constant speed power mechanism and fluid pump are located at a surface of the borehole, the fluid pump is capable of pumping borehole fluid down the borehole, and the borehole is for a hydrocarbon production operation.
