Using mines and tunnels for treating subsurface hydrocarbon containing formations

摘要

A system for treating a subsurface hydrocarbon containing formation is disclosed. The system includes one or more tunnels. The tunnels have an average diameter of at least 1 m. At least one tunnel is connected to the surface. Two or more wellbores extend from at least one of the tunnels into at least a portion of the subsurface hydrocarbon containing formation. At least two of the wellbores contain elongated heat sources configured to heat at least a portion of the subsurface hydrocarbon containing formation such that at least some hydrocarbons are mobilized.
