  • Patent number: 6834724
    Abstract: The disclosure describes a spoolable compliant guide, a system including a spoolable compliant guide and injector and methods for using the compliant guide, where the guide is designed to connect at one end to the injector and at its other end to a remote installation having a seal and to allow coiled tubing to be inserted into the installation through the seal. Because the guide permits a substantial distance to exist between the injector and the installation seal and functions as a crimp or band resistor for the coiled tubing, the guide enables the injector to be conveniently positioned remote from the installation such as a wellhead and assumes a compliant shape between the injector and the installation allowing dynamic relative movement between them without the use of heave compensators. Thus, for subsea installations, the injector, its control system and coiled tubing reels can all be located on the water's surface for ease of access and maintenance.

  • Patent number: 6772840
    Abstract: A flow assurance system includes an inner pipe disposed within an outer pipe to assure flow through the outer pipe. During installation and relative axial movement with the outer pipe, the inner pipe is nearly neutrally buoyant or fully neutrally buoyant in the fluids of the outer pipe and may extend partially or completely through the outer pipe. The inner pipe may be anchored at one end within the outer pipe. The inner pipe is preferably composite coiled tubing that is installed using a propulsion system. The system may allow fluids to flow through the inner pipe and commingle with the fluids in the outer pipe or may flow fluids through the inner pipe to the exterior of the outer pipe. Hot fluids may pass through the inner pipe to maintain the temperature of the fluids flowing through the outer pipe and chemicals may flow through the inner pipe to condition the fluids in the outer pipe. Tools may be attached to the end of the inner pipe for conducting flow assurance operations within the outer pipe.

  • Publication number: 20020079108
    Abstract: The present invention provides a system including a spoolable compliant guide, injector and lubricator to obtain vertical access to any oil well and to insert coiled tubing therein to. The spoolable compliant guide provides a substantial distance between the injector and the annular well seal at the lubricator and functions as a crimp or bend resistor for the coiled tubing therein facilitating the imposition of compression forces thereon. This enables the injector to be conveniently positioned remote from the wellhead, not necessarily vertically above the wellhead, on the facility with the wellheads or on an entirely separate facility, vehicle or vessel. Wellheads on land, offshore or underwater can all be accessed. Pressurized well fluids are prevented from entering the spoolable compliant guide thus decreasing the risks associated with its damage, failure or emergency disconnection.
