Claim 0:
1. A method for increasing one or more of engine, generator set, or bottom-hole assembly performance, the method comprising:
sensing, via a first sensor, a temperature of a flow of drilling fluid from a borehole;
sensing, via a second sensor, an ambient temperature of a drilling rig;
determining electrical power utilized by drilling rig equipment and generated by a generator set driven by an engine; and
in response to one or more of (a) a determination that the temperature of the flow of drilling fluid from the borehole exceeds an operating range, (b) a determination that the ambient temperature exceeds an ambient temperature threshold, (c) a determination that the electrical power utilized by the drilling rig equipment exceeds a power requirement threshold, or (d) a determination that the ambient temperature exceeds an engine operating range:
adjusting one or more of (1) a first working fluid flow control device to control a flow of working fluid to a drilling fluid heat exchanger, the drilling fluid heat exchanger configured to transfer heat from the drilling fluid to the flow of the working fluid, thereby to cause a power generation unit to generate electrical power, (2) a second working fluid flow control device to control a flow of working fluid to an exhaust heat exchanger, the exhaust fluid heat exchanger configured to transfer heat from exhaust generated by the engine to the flow of the working fluid, thereby to cause a power generation unit to generate electrical power, or (3) a third working fluid flow control device to control a flow of working fluid to a fluid jacket heat exchanger, the fluid jacket fluid heat exchanger configured to transfer heat from the fluid of the fluid jacket to the flow of the working fluid, thereby to cause a power generation unit to generate electrical power.
