Method for treating a hydrocarbon containing formation are described
herein. Methods may include providing heat to two or more first sections
of the formation with one or more first heaters in two or more of the
first sections. The provided heat may mobilize first hydrocarbons in two
or more of the first sections. At least some of the mobilized first
hydrocarbons are produced through production wells located in two or more
second sections of the formation. The first sections and the second
sections are arranged in a checkerboard pattern. A portion of at least
one of the second sections proximate at least one production well is
provided some heat from the mobilized first hydrocarbons, but is not
conductively heated by heat from the first heaters. Heat may be provided
to the second sections with one or more second heaters in the second
sections to further heat the second sections.
