Abstract:
A system for treating a subsurface hydrocarbon containing formation includes one or more shafts. At least two substantially horizontal or inclined tunnels extend from one or more of the shafts. A plurality of heat sources are located in at least one heat source wellbore extending between at least two of the substantially horizontal tunnels. Electrical connections for the heat sources are located in at least one of the substantially horizontal tunnels.
