    摘要: A method of heating a subsurface formation includes introducing a molten salt into a first passageway of a conduit-in-conduit heater at a first location. The molten salt is passed through the conduit-in-conduit heater in the formation to a second location. Heat transfers from the molten salt to a treatment area during passage of the molten salt through the conduit-in-conduit heater. The molten salt is removed from the conduit-in-conduit heater at a second location spaced away from the first location.

    摘要: A heating system for a subsurface formation includes an elongated electrical conductor located in the subsurface formation. The electrical conductor extends between at least a first electrical contact and a second electrical contact. A ferromagnetic conductor at least partially surrounds and at least partially extends lengthwise around the electrical conductor. The electrical conductor, when energized with time-varying electrical current, induces sufficient electrical current flow in the ferromagnetic conductor such that the ferromagnetic conductor resistively heats to a temperature of at least about 300° C.

    摘要: A method of treating a subsurface formation includes circulating at least one molten salt through at least one conduit of a conduit-in-conduit heater located in the formation to heat hydrocarbons in the formation to at least a mobilization temperature of the hydrocarbons. At least some of the hydrocarbons are produced from the formation. An electrical resistance of at least one of the conduits of the conduit-in-conduit heater is assessed to assess a presence of a leak in at least one of the conduits.
