Abstract of the Disclosure A subterranean viscous oil bearing formation is progressively produced in a preselected direction by a combination of steps conducted in sets of wells spaced from each other in the preselected direction. A first set of wells is used to both apply electrical heat to the for- mation and inject brine, preferably at low rates. Then electrical heating and brine injection are applied to a second set of wells spaced in the preselected direction from the first set of wells. Electrical heating in the first of wells is ceased and hot aqueous fluid injection is commenced. These steps are moved in sequence to coact with each other and traverse and produce the formation thereby providing a more energy efficient process. Varia- tions cover electrically stimulated huff and puff backflowing or producing steps to control wellbore resistance and distri- bute the heat uniformly in the proper direction. A pressure maintenance fluid may also be injected in the depleted part of the formation.
