    摘要: A system for treating a subsurface formation includes a wellbore at least partially located in a hydrocarbon containing formation. The wellbore includes a substantially vertical portion and at least two substantially horizontal or inclined portions coupled to the vertical portion. A first conductor is at least partially positioned in a first of the two substantially horizontal or inclined portions of the wellbore. At least the first conductor includes electrically conductive material. A power supply electrically excites the electrically conductive materials of the first conductor such that current flows between the electrically conductive materials in the first conductor, through at least a portion of the formation, to a second conductor at least partially positioned in a second of the two substantially horizontal or inclined portions of the wellbore. The current resistively heats at least a portion of the formation between the two substantially horizontally oriented or inclined portions of the wellbore.

    摘要: A method for treating a tar sands formation includes providing heat from a first heater located between a steam injection well and a production well in a hydrocarbon containing layer. The first heater, the steam injection well, and the production well are located substantially horizontally in the layer. Heat is provided from a second heater horizontally offset from the first heater. The second heater is located vertically above an injection/production well and substantially horizontally in the layer. Steam is injected into the layer through the steam injection well after a selected amount of heat is provided from the first heater. Hydrocarbons are produced from the layer through the production well. Steam is injected and hydrocarbons are produced alternately through the injection/production well after a selected amount of heat is provided from the second heater.
