Producing hydrocarbons and non-hydrocarbon containing materials when treating a hydrocarbon containing formation

A method of treating a hydrocarbon containing formation in situ, compnsing:

• providing heat to a portion of the formation;
• allowing the heat to transfer from the portion to a selected section of the formation such that dissociation of carbonate minerals is inhibited;
• injecting a first fluid into the selected section;
• conducting an in situ conversion process in the selected section;
• producing a second fluid from the formation, wherein the second fluid includes nahcolite;
• separating at least a portion of the nahcolite from the second fluid;
• providing heat to at least some of the separated nahcolite to form a sodium carbonate solution;
• providing at least some of the sodium carbonate solution to at least the portion of the formation;
• and
• producing a third fluid including alumina from the formation.

A method of treating a hydrocarbon containing formation in situ, comprising:

• providing heat to a portion of the formation;
• allowing the heat to transfer from the portion to a selected section of the formation such that dissociation of carbonate minerals is inhibited;
• controlling the heat provided to the formation such that a temperature in the selected section of the formation is less than about 100° C.;
• injecting a first fluid into the selected section;
• producing a second fluid from the formation;
• and
• conducting an in situ conversion process in the selected section.

A method of treating a hydrocarbon containing formation in situ, comprising:

• providing heat from one or more heaters to a portion of the formation;
• allowing the heat to transfer from the portion to a selected section of the formation such that dissociation of carbonate minerals is inhibited;
• injecting a first fluid into the selected section;
• producing a second fluid from the formation;
• conducting an in situ conversion process in the selected section;
• pyrolyzing at least some hydrocarbons in the selected section of the formation;
• producing a mixture from the formation;
• reducing a temperature of the selected section of the formation;
• injecting a third fluid into the selected section;
• and
• producing a fourth fluid from the formation.

A method of treating a hydrocarbon containing formation in situ, comprising:

• providing heat to a portion of the formation;
• allowing the heat to transfer from the portion to a selected section of the formation such that dissociation of carbonate minerals is inhibited;
• injecting a first fluid into the selected section, wherein a temperature in the selected section is less than about 90° C.;
• producing a second fluid from the formation;
• and
• conducting an in situ conversion process in the selected section.
