A wellbore with a plurality of fractures 7, 9 designated as one of a first or a second set of fractures is provided. A first fluid conduit 11 is located in the wellbore and arranged to transport produced hydrocarbons, and a second fluid conduit 12 is located in the wellbore and arranged to transport an injection fluid. A set of first openings 14 is provided in fluid connection with the first fluid conduit 11, each first opening being located to substantially align with one of a first set of fractures 7. A set of second openings 15 is provided in fluid connection with the second fluid conduit 12, each second opening 15 being located to substantially align with one of a second set of fractures 9. A high pressure fluid is injected into the second set of fractures 9, which pushes hydrocarbons located in the low permeability reservoir towards the first set of fractures 7, thereby increasing the recovery rate of hydrocarbons in the low permeability reservoir. |
