Abstract
A method of heating a subsurface hydrocarbon containing formation includes providing heat flux per volume to a first portion of a subsurface hydrocarbon containing formation. The heat flux per volume is provided by two or more first heat sources positioned in the first portion. Heat flux per volume is provided to a second portion of the subsurface hydrocarbon containing formation with the heat flux per volume being provided by two or more second heat sources positioned in the second portion. The heat flux per volume provided by the two or more second heat sources is greater than the heat flux per volume provided by the two or more first heat sources. The second portion is positioned below the first portion.
