摘要： A method for capturing hydrocarbons from a formation is provided. After a first hydraulic fracturing of a formation to produce a first conditioned formation, and while hydrocarbons are being produced from the first conditioned formation, a predetermined wellbore characteristic is monitored for. The predetermined wellbore characteristic is based on at least a pressure within the first conditioned formation. After detecting the predetermined wellbore characteristic, a second hydraulic fracturing of the formation is effected to produce a second conditioned formation.

摘要： 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.
