Abstract
A system for treating a subsurface formation includes a plurality of conduits at least partially located in a portion of a hydrocarbon containing formation. At least part of two of the conduits are aligned in relation to each other such that electrical current will flow from a first conduit to a second conduit. The first and second conduits include electrically conductive material and at least one of the first and second conduits is perforated or configured to be perforated. A power supply is coupled to the first and second conduits. The power supply electrically excites at least one of the conductive sections such that current flows between the first conduit and the second conduit in the formation and heats at least a portion of the formation between the two conduits.
