Abstract (en)
[origin: WO2014162094A2] The invention relates to a method for extracting hydrocarbons comprising the steps involving extracting a process flow from an underground formation, separating this flow into at least one hydrocarbon‑containing fraction and one aqueous fraction referred to as the produced water, and reinjecting an injection water into the underground formation. The injection water intended to be introduced into the underground formation is produced partly in a direct‑osmosis unit from produced water and partly in a nano filtration and/or reverse‑osmosis unit. The invention also relates to a more general process for extracting hydrocarbons throughout the exploitation life of the underground hydrocarbon reservoir, and to an injection‑water production device especially designed for implementing this process.
