The present disclosure relates to a particularly effective well configuration that can be used for heat based oil recovery methods. Fishbone multilateral wells are combined with inline electric heaters and a thermally conductive proppant. Preferably, an array of overlapping fishbone wells cover the pay, allowing more complete production of the pay, and the use of the proppants prevents the open-hole fishbone laterals from collapsing. These methods can be applied in variety of configurations, including traditional vertically spaced well-pairs, laterally spaced well-pairs, producers only, and combinations thereof.
