SYSTEMS AND METHODS FOR TREATING A SUBSURFACE FORMATION WITH ELECTRICAL CONDUCTORS

摘要

Systems and methods for treating a subsurface formation are described herein. The system includes a wellbore at least partially located in a hydrocarbon containing formation. The wellbore includes a substantially vertical portion and at least two substantially horizontally oriented or inclined portions coupled to the vertical portion. A first conductor is at least partially positioned in a first of the two substantially horizontal oriented or inclined portions of the wellbore and includes electrically conductive material. A power supply is coupled to at least the first conductor and is configured to electrically excite 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 and heats at least a portion of the formation between the two substantially horizontally oriented or inclined portions of the wellbore.
