    Abstract: The invention provides an in situ conversion system for producing hydrocarbons from a subsurface formation, that includes: a plurality of u-shaped wellbores in the formation; piping positioned in at least two of the u-shaped wellbores; a fluid circulation system coupled to the piping, and an electrical power supply. The fluid circulation system is configured to circulate hot heat transfer fluid through at least a portion of the piping to form at least one heated portion of the formation. The electrical power supply is configured to provide electrical current to at least a portion of the piping (220) located below an overburden in the formation to resistively heat at least a portion of the piping and the heat transfers from the piping to the formation. The invention also provides methods of using the in situ conversion system to produce hydrocarbons from the subsurface formation.

    Abstract: Electrical current flow is induced in a ferromagnetic conductor providing time-varying electrical current at a first frequency to an electrical conductor located in a formation. The ferromagnetic conductor at least partially surrounds and at least partially extends lengthwise around the electrical conductor. The ferromagnetic conductor resistively heats up to a first temperature of at most about 300° C. Water in the formation is vaporized with heat at the first temperature. Subsequently, time-varying electrical current at a second frequency is provided to the elongated electrical conductor to induce electrical current flow at the second frequency such that the ferromagnetic conductor resistively heats up to a second temperature above about 300° C. Heat transfers from the ferromagnetic conductor at the second temperature to at least a part of the formation to mobilize at least some hydrocarbons in the part of the formation.
