  • Lining of well bores with expandable and conventional liners
    Patent number: 9816358
    Abstract: Reducing the diameter of a well bore has many advantages. To achieve this a subsurface well bore is provided comprising one or more expandable sleeve components, preferably expandable liners, each expandable sleeve component being fully overlapped by one or more non expandable sleeve component, preferably conventional liners, such that the interior of the well bore is cased entirely by non expandable sleeve components. In addition the through holes for downhole lines can be provided within the well head rather than the tubing hanger. As the tubing hanger does not need to provide space for through holes and associated mounting couplings, its diameter can be reduced, thus reducing the internal diameter of the well bore by several inches.

  • Lining of well bores with expandable and conventional liners
    Patent number: 9347296
    Abstract: Reducing the diameter of a well bore has many advantages. To achieve this a subsurface well bore is provided comprising one or more expandable sleeve components, preferably expandable liners (27, 271), each expandable sleeve component being fully overlapped by one or more non expandable sleeve component, preferably conventional liners (28, 29), such that the interior of the well bore is cased entirely by non expandable sleeve components (28, 29). In addition the through holes (34a) for downhole lines can be provided within the well head (34) rather than the tubing hanger (33). As the tubing hanger does not need to provide space for through holes and associated mounting couplings, its diameter can be reduced, thus reducing the internal diameter of the well bore by several inches.

  • Method for modifying an existing subsea arranged oil production well, and a thus modified oil production well
    Patent number: 9234402
    Abstract: Method to modify an existing subsea arranged oil production well having installed a hydraulically operated downhole valve, characterized in using coiled tubing technology to: arrange an electrically operated downhole pump in the production tubing, lock the hydraulically operated downhole valve in an open position by placing a sleeve body in the open positioned valve, arrange an electrically operated downhole valve above the downhole pump. A modified oil production well.
