A hydrocarbon 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. The mixture may be produced from the formation through a plurality of production wells. A selected number of heat sources may be positioned in the formation for each production well.

A coal 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 may be allowed to transfer from one or more heat sources to a selected section of the formation such that superimposed heat from the one or more heat sources pyrolyzes a relatively large portion of hydrocarbon material within the selected section of the formation.

A hydrocarbon 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. A pressure within a majority of the portion may be controlled and/or maintained to alter a composition of the produced mixture.

A hydrocarbon 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. A formation to be treated may produce a relatively large amount of condensable hydrocarbons and/or a relatively large amount of non-condensable hydrocarbons. Hydrocarbons within the formation may have a relatively low initial elemental oxygen weight percentage.

A method for treating subsurface formation includes providing a hydrocarbon-containing feed stream produced from an in situ heat treatment process. At least a portion of the hydrocarbon-containing feed stream is treated with one or more aqueous acid compounds to produce an aqueous stream including organonitrogen compounds. At least a portion of the aqueous stream including organonitrogen compounds is provided to at least a portion of a formation that has been at least partially treated by an in situ-heat treatment process.

A method includes producing formation fluid from a subsurface in situ heat treatment process. The formation fluid is separated to produce a liquid stream and a gas stream. At least a portion of the liquid stream is provided to a hydrotreating unit. At least a portion of selected in situ heat treatment clogging compositions in the liquid stream are removed to produce a hydrotreated liquid stream by hydrotreating at least a portion of the liquid stream at conditions sufficient to remove the selected in situ heat treatment clogging compositions.
