The oil shale formation may be treated using an in situ thermal process. Heat
may be provided to a section of the formation from one or more heat sources. A
portion of a heat source may include conductive material. In some embodiments,
the conductive portion may reduce heat loss to a non-hydrocarbon containing layer
in the formation. Heat may be allowed to transfer from the heat sources to a section
of the formation. Hydrocarbons, H2, and/or other formation fluids may
be produced from the formation.
