Cogeneration systems and processes for treating hydrocarbon containing formations

A method for treating a hydrocarbon containing formation, comprising:

• providing steam to a first portion of the formation;
• producing at least some first hydrocarbons from the first portion of the formation;
• providing heat from one or more electrical heaters to a second portion of the formation;
• allowing the provided heat to transfer from the heaters to the second portion of the formation;
• producing at least some second hydrocarbons from the second portion of the formation;
• using at least a portion of the first hydrocarbons and/or the second hydrocarbons in a steam and electricity generation facility, wherein the facility provides steam to the first portion of the formation and electricity for at least some of the heaters;
• and
• using at least a portion of the second hydrocarbons as a gas for one or more additional heaters in the formation, wherein at least one of the additional heaters is configured to combust the gas.

A system for treating a hydrocarbon containing formation, comprising:

• a steam and electricity cogeneration facility;
• at least one injection well located in a first portion of the formation, the injection well configured to provide steam from the steam and electricity cogeneration facility to the first portion of the formation;
• at least one production well located in the first portion of the formation, the production well configured to produce first hydrocarbons;
• at least one electrical heater located in a second portion of the formation, at least one of the electrical heaters configured to be powered by electricity from the steam and electricity cogeneration facility;
• at least one production well located in the second portion of the formation, the production well configured to produce second hydrocarbons;
• wherein the first and second portions are separated from each other by a barrier or by a substantially impermeable zone of the formation;
• and
• the steam and electricity cogeneration facility is configured to use at least a portion of the first hydrocarbons and/or the second hydrocarbons to generate electricity.
