  • Publication number: 20130306327
    Abstract: A bridge plug can be deployed downhole and retrieved using a retrieval tool disposed on jointed or coiled tubing or on another bridge plug. Internally, the bridge plug has a sleeve that is movable on a stem of the plug's tailpiece. When in a first position, the sleeve prevents fluid communication through ports in the stem so that circulated fluid from the retrieval tool can be used to clear debris from the plug during retrieval. When the retrieval tool engages the sleeve in the plug, pulling up on the tool moves the sleeve to an intermediate position in which fluid pressure is equalized across the plug. Further pulling up on the tool locks the sleeve in a further position on the stem so that circulated fluid from the retrieval tool will pass directly to the stem's ports. Movement of the sleeve by the retrieval tool also releases the engaged slips and packing element on the bridge plug's mandrel.

    Abstract: A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.

  • Patent number: 8544552
    Abstract: For injecting e.g. water into ground formation around a borehole, and for superimposing pulses onto the outflow of the injected water, it is important that the pulses have a rapid rise-time. A piston is connected to a pulse-valve of the tool. A bias spring urges the piston towards its closed position. The piston is urged towards the open position by a differential PDAF between the supplied accumulator-pressure and the in-ground formation-pressure. When the pulse-valve is open, the PDAF is falling, until the force of the spring closes the pulse-valve. Then the PDAF rises, but now the PDAF acts over only a small area of the piston. When the PDAF is high enough to ease the pulse-valve open, suddenly the whole area of the piston is exposed to the PDAF, whereby the pulse-valve opens violently.

  • Publication number: 20130248203
    Abstract: Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly.
