Systems and methods for delivery of thermal energy to horizontal wellbores are disclosed. In one embodiment, a method comprises heating a heat transfer fluid; circulating the heat transfer fluid into a vertical bore to a heat exchanger; advancing feedwater into the vertical bore to the heat exchanger, wherein the heat exchanger is configured to transfer heat from the heat transfer fluid to the feedwater to generate steam; transmitting the steam from the heat exchanger into a horizontal wellbore to cause heating of a subterranean region; and returning the heat transfer fluid from the heat exchanger to the surface. The method may further comprise collecting liquefied formation in a second horizontal wellbore; and transmitting the liquefied formation to the surface through a production line.
