A method for treating a hydrocarbon containing formation is provided. In one embodiment, heat from one or more heaters may be provided to at least a portion of the formation. Heat may be allowed to transfer from the one or more heaters to at least a part of the formation. In certain embodiments, the heat from the one or more heaters may pyrolyze at least some hydrocarbons in the formation. In an embodiment, a first fluid may be introduced into at least a portion of the formation. The portion may have previously undergone an in situ conversion process. A mixture of the first fluid and a second fluid may be produced from the formation. Such mixture may, in some embodiments, be treated or burned.

Treatment of a hydrocarbon containing formation after heating

A method is described for inhibiting migration of fluids into and/or out of a treatment area undergoing an in situ conversion process. Barriers in the formation proximate a treatment area may be used to inhibit migration of fluids. Inhibition of migration of fluids may occur before, during, and/or after an in situ treatment process. For example, migration of fluids may be inhibited while heat is provided from heaters to at least a portion of the treatment area. Barriers may include naturally occurring portions (e.g., overburden, and/or underburden) and/or installed portions.

In situ recovery from a hydrocarbon containing formation using barriers

An oil shale formation may be treated using an in situ thermal process. Fluid migration into and/or out of a treatment area in the formation may be inhibited. In some embodiments, a barrier may be used to inhibit migration of fluids into and/or out of the treatment area. Heat may be provided to the treatment area and subsequently, hydrocarbons, H, and/or other formation fluids may be produced from the formation.

In situ thermal processing and inhibiting migration of fluids into or out of an in situ oil shale formation

An oil shale formation may be treated using an in situ thermal process. Heat may be provided to a portion of the formation from one or more heat sources. Heat may be allowed to transfer from the heat sources to a selection of the formation. Hydrocarbons, H, and/or other formation fluids may be produced from the formation. A recovery fluid may be provided to the formation to recover one or more components remaining in the portion.
