Methods for heating with slots in hydrocarbon formations

A method of treating a hydrocarbon containing formation, comprising:

• allowing the heat to transfer from a plurality of heaters to a first section of the formation;
• producing hydrocarbons from the hydrocarbon containing formation;
• forming one or more slots in a portion of the hydrocarbon containing formation, wherein at least one of the slots extends from a side of a wellbore and is perpendicular to at least two substantially horizontal or inclined portions of the wellbore positioned in the hydrocarbon containing formation;
• providing heat to a second section of the hydrocarbon containing formation from one or more additional heaters placed in at least one of the slots;
• allowing the heat to transfer from the heaters to the second section of the formation;
• and
• producing additional hydrocarbons from the hydrocarbon containing formation.

A method of producing methane from a hydrocarbon containing formation, comprising:

• forming at least one wellbore in a hydrocarbon containing formation, the wellbore comprising at least two substantially horizontal or inclined portions, a first opening at a first position of the earth's surface and a second opening at a second position of the earth's surface;
• forming one or more slots in a portion of the hydrocarbon containing formation, wherein at least one of the slots extends from a side of the wellbore and is perpendicular to the at least two substantially horizontal or inclined portions of the wellbore;
• providing heat to a portion of the hydrocarbon containing formation from one or more heaters placed in at least a portion of one of the slots, wherein one or more of the heaters comprise one or more insulated electrical conductors;
• maintaining an average temperature in the portion of the formation below a pyrolyzation temperature of hydrocarbons in the section;
• and
• removing methane from the hydrocarbon formation.
