    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 first conductor is positioned in the substantially horizontal or inclined portion of a first wellbore. The first conductor includes electrically conductive material. A portion of the first conductor positioned in the first wellbore includes copper coupled to the electrically conductive material. The copper tapers from a larger thickness at a first end of the portion to a smaller thickness at a second end of the portion. A power supply coupled to the first conductor 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 located in the hydrocarbon containing layer in the formation, and the current resistively heats at least a portion of the formation between the two conductors.
