Abstract: There is provided a more compensating secondary sealing system for misalignments that inevitably occur in sealing subsurface valves, particularly subsurface safety valves. A sealing system can include a dynamic sealing system (51) and a static sealing system (50), where the static sealing system (50) establishes one or more line contact surfaces (82, 88). The line contact surfaces (82, 88) can be leading, in that the forward edge of the seal faces a corresponding engagement portion (114) of the actuator (36). The actuator (36) can include at least two spherical engagement portions where one of the spherical engagement portions (114) engages resilient and non-resilient seals (76, 62) with line contact surfaces (82, 88) on a downstroke and the other spherical engagement portion (not shown) engages resilient and non-resilient seals with line contact surfaces on an upstroke. Further, a bearing (73) disposed above seals on a piston (40) of the actuator (36) assists in keeping contaminants out of the seal area of the piston (40).

Abstract: The present invention generally provides a method and apparatus for injecting a compressible fluid at a controlled flow rate into a geological formation at multiple zones of interest. In one aspect, the invention provides a tubing string with a pocket and a nozzle at each isolated zone. The nozzle permits a predetermined, controlled flow rate to be maintained at higher annulus to tubing pressure ratios. The nozzle includes a diffuser portion to recover lost steam pressure associated with critical flow as the steam exits the nozzle and enters a formation via perforations in wellbore casing. In another aspect, the present invention assures that the fluid is supplied uniformly to a long horizontal wellbore by providing controlled injection at multiple locations that are distributed throughout the length of the wellbore. In another aspect, the invention ensures that saturated steam is injected into a formation in a predetermined proportion of water and vapor by providing a plurality of apertures between a tubing wall and a pocket. The apertures provide distribution of steam that maintains a relative mixture of water and vapor. In another aspect of the invention, a single source of steam is provided to multiple, separate wellbores using the nozzle of the invention to provide a controlled flow of steam to each wellbore.

Abstract: A collar (500) for injecting fluid, such as a formation treating fluid, into a wellbore, and a method for using same. The collar is disposed between the upper and lower packing elements (40, 41) of a pack-off system during the treatment of an area of interest within a wellbore. The collar first comprises an inner mandrel (550) running essentially the length of the collar. The inner bore of the collar is in fluid communication with the annular region between the collar and the surrounding perforated casing by a set of actuation ports (552). A second set of ports (554), known as frac ports, is disposed within the mandrel. In accordance with one aspect of the invention, the collar further comprises a tubular case which substantially seals the frac ports in a first position, and slidably moves along the outer surface of the mandrel in order to expose the frac ports in a second position. In operation, the upper and lower packing elements are set at a first fluid pressure level. Upon application of a second greater fluid pressure level, the upper and lower packing elements are further separated in accordance with a designed stroke length, thereby exposing the frac ports.

Abstract: A liner hanger having a mechanical coupling between a liner hanger body and one or more cones is disclosed. The cones are coupled to the liner hanger body to resist axial and relative rotational movement without welding the cones to the hanger body, and without the need to use integral cones. In general, the mechanical coupling includes a hanger body or casing mandrel, a cone assembly journaled on the casing mandrel, at least one slot or groove in an outer wall of the casing mandrel, and at least one partially or fully annular slot on the inside surface of the cone assembly oriented to correspond with the groove(s) in the outer wall of the hanger body. At least one wire, or one or more bearings, is situated in the corresponding slot and the groove. The wire engages the flanks of the slot and groove sufficiently to resist axial or rotational movement of the cones relative to the hanger body.

Abstract: The present invention provides methods and apparatus for reducing friction and preventing galling between surfaces in a wellbore. In one aspect of the invention, mating threads are coated with fullerene to reduce galling of the threads during make up and break down. In another aspect, a fullerene is used between surfaces of an expansion tool and a tubular to be expanded in order to reduce friction and prevent galling therebetween. Preferably, the fullerene is a spherically shaped carbon 60 molecule otherwise known as buckyball or C 60 . The fullerene coating provides an intermediate surface between two metal surfaces, thereby preventing galling between the two surfaces. In another aspect of the invention, the fullerene is placed between the roller of an expander tool and the surface of the tubular to be expanded in order to reduce friction and galling.

Abstract: The present invention provides an encapsulation for housing instrumentation lines, control lines, or instruments downhole. In one use, the encapsulation (10) resides between an expandable downhole tool (20), such as an expandable sand screen, and the wall (48) of the wellbore. The encapsulation is specially profiled to allow the downhole tool to be expanded into the wall of the wellbore without leaving a channel outside of the tool through which formation fluids might vertically migrate. The encapsulation is useful in both cased hole and open hole completions.
