Abstract
The disclosure relates to a technique for controlled or uniform temperature heating of a volume of hydrocarbonaceous material in an earth formation employing conductor arrays, inserted in the formation, for applying radio frequency energy to the formation. The number and spacing of conductors in the arrays are selected to provide a concentration of electric field intensity at the extremities of the volume to facilitate controlled or uniform temperature heating of the volume. The arrangement compensates for temperature variations across the volume caused by heat flow within the volume and heat loss to the surrounding formation.
