  • PROCESSES FOR PRODUCING HYDROCARBONS FROM A RESERVOIR
    Publication number: 20190257183
    Abstract: There is provided a process for producing hydrocarbons from a reservoir. The process includes within the hydrocarbon reservoir, electrically heating a liquid heating fluid such that the liquid heating fluid is evaporated to produce a gaseous heating fluid, heating hydrocarbon material with the gaseous heating fluid such that the heated hydrocarbon material is mobilized and such that the gaseous heating fluid is condensed to produce a condensed heating fluid, and electrically heating at least a fraction of the condensed heating fluid such that the at least a condensed heating fluid fraction is re-evaporated, and while the evaporation, the condensing, and the re-evaporation are being effected, producing a produced fluid including at least the mobilized hydrocarbon material.
    Type: Application
