In situ thermal processing of an oil shale formation having permeable and impermeable sections

摘要

An oil shale formation may be treated using an in situ thermal process. Heat may be provided to a formation from one or more heat sources in the formation. Hydrocarbons within the formation may be pyrolyzed. Hydrocarbons, H2, and/or other formation fluids may be produced from the formation. In some embodiments, the formation may include a relatively impermeable portion and/or a relatively permeable portion.
