1. A method to generate geothermal power, the method comprising:
opening, to at least a partially opened position, one or more heat exchanger valves positioned between one or more heat exchangers and a wellhead fluid flow line;
determining, based on feedback from one or more temperature sensors, a temperature of an organic working fluid in a working fluid flow line, the temperature of the organic working fluid based on heat transfer from a flow of wellhead fluid from the wellhead to the organic working fluid; and
in response to a determination that the temperature of the organic working fluid is greater than or equal to a vaporous phase change threshold of an organic working fluid, maintaining the at least partially open position of the one or more heat exchanger valves to allow continuous diversion of the flow of the wellhead fluid to one or more heat exchangers to facilitate transfer of heat from the flow of the wellhead fluid to the organic working fluid through the one or more heat exchangers, thereby to generate heated organic working fluid so that the heated organic working fluid causes an electrical generator unit to generate electrical power and so that at least portions of the generated electrical power provides electrical power to one or more of (a) in-field oil or gas equipment, (b) other in-field operational equipment, (c) a grid power structure, or (d) an energy storage device.
