Claim 19:
20. A mobile heat generation unit comprising:
a transportable package including a frame having a chamber therein and a frame footprint, the transportable package further comprising:
at least one heat exchanger located within the chamber,
one or more valves positioned along a conduit extending between the at least one heat exchanger and a heat source, thereby to enable a flow of a high pressure or high temperature wellhead fluid to flow from the heat source to the at least one heat exchanger;
a controller having programming configured to:
actuate the one or more valves to enable flow therethrough in response to a pressure of the high pressure or high temperature wellhead fluid being below a threshold of the at least one heat exchanger, and
monitor temperature, pressure, or a combination thereof of a working fluid passing along a fluid recirculation loop defined between the mobile heat generation unit and at least one ORC unit and to regulate flow of the working fluid through the at least one heat exchanger for transfer of heat from the flow of the high pressure or high temperature fluid to the working fluid; and

a fluid recirculation system comprising:
a fluid intake conduit coupled in fluid communication with the at least one ORC unit to receive the working fluid from the at least one ORC unit,
a fluid outlet conduit in fluid communication with the at least one ORC unit to supply the working fluid thereto, wherein the working fluid is supplied to the at least one ORC unit,
a pump connected to the fluid intake conduit and configured to pump the working fluid received through the fluid intake conduit, and
a piping array including (a) a first section of piping extending between the pump and the at least one heat exchanger for supplying the working fluid to the at least one heat exchanger, and (b) a second section of piping extending between the at least one heat exchanger and the fluid outlet conduit, at least a portion of the fluid intake conduit extends adjacent a portion of the frame and connects to the first section of piping, and at least a portion of the fluid outlet conduit extends adjacent a portion of the frame and connects to the second section of piping, so that during operation as the working fluid passes along the piping array and through the at least one heat exchanger, heat from the high pressure or high temperature fluid supplied to the at least one heat exchanger from the heat source transfers to the working fluid so as to heat the working fluid for supply to the at least one ORC unit.
