Abstract: Production of heavy oil and bitumen from a reservoir is enhanced by cyclic radio frequency (RF) radiation of the well. The invention utilizes RF radiation to introduce energy to the hydrocarbon reservoir in cycles in order to heat the reservoir directly, yet conserves energy over the prior art processes that more or less continuously apply RF or microwave energy. The advantage of cyclic RF is it uses less electricity, and thus lowers operating costs. This is achieved by the soak cycle that allows heat to conduct into the formation and assists the heat penetration that is directly radiated into the formation by the antenna. The invention can also be advantageously combined with cyclic steam stimulation.
