Abstract: A method for producing heavy oil using solvent injection without gas interference at the electric submersible pump (ESP), the method including completing the injection well with two or more injector tubings, at a heel and toe, and optionally therebetween. Ideally, when gas locking of the ESP is detected, the operator switches to toe dominant injections, mitigating the gas locking problem, and producing oil at a faster rate than possible with evenly distributed injections.
