Claim 24:
25. A method for generating geothermal power, the method comprising:
locating one or more mobile heat generation units at a hydrocarbon production site, the one or more mobile heat generation units each comprises a package having at least one heat exchanger, a controller, and a fluid recirculation system including a pump, a fluid inlet conduit through which a flow of a working fluid is received in a substantially liquid phase, a fluid outlet conduit through which the working fluid is supplied in a substantially vapor phase, and a fluid path extending from the pump through the at least one heat exchanger and to the fluid outlet conduit;
connecting the at least one heat exchanger of the one or more mobile heat generation units to a heat source, thereby to define a fluid path extending from the heat source through the at least one heat exchanger, the heat source to include a wellhead fluid source;
opening one or more valves positioned between the at least one heat exchanger and the heat source connected thereto to enable a flow of heated fluid along the fluid path extending from the heat source through the at least one heat exchanger in response to a determination that a pressure of the flow of heated fluid is below a threshold of the at least one heat exchanger;
pumping the working fluid along the fluid path extending from the pump through the at least one heat exchanger and to the fluid outlet conduit;
transferring heat, via the at least one heat exchanger, from the flow of heated fluid to the working fluid when pumped through the at least one heat exchanger, to cause a change in phase of the working fluid from a liquid to a vapor, which is thereafter supplied to one or more ORC units to drive a generator for generation of electrical power from an ORC operation;
monitoring temperature of the working fluid, pressure of the working fluid, ambient weather conditions, or a combination thereof; and
operating one or more control valves to regulate the flow of the working fluid to control the temperature or pressure thereof.
