Abstract
A coal containing formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat sources within a relatively thin layer of coal may be positioned in a staggered pattern near to edges of the layer so that superposition of heat from the heat sources allows a large percentage of the layer to reach a desired temperature.
