  • Patent number: 7798212
    Abstract: A technique is provided to facilitate connection of completion assemblies at a downhole location. A completion assembly comprises a control line conduit having a connector designed for coupling with a corresponding connector of a next adjacent completion assembly. A cover is selectively used to block entry of debris and other contaminants into the connector during deployment of the completion assembly downhole prior to engagement with the next adjacent completion of assembly.
    Type: Grant

  • Patent number: 7510003
    Abstract: A technique is provided in which a soft landing system is used for connecting upper and lower assemblies in a wellbore. The soft landing system cushions the engagement of an upper well assembly with a lower well assembly and facilitates the controlled engagement of control line connectors. The controlled engagement limits or avoids damage to the control line connectors in well completion operations performed in two or more stages.

  • Patent number: 7503395
    Abstract: A technique is provided to facilitate connection of well equipment assemblies at a downhole location. A first assembly comprises a control line having a connector designed for coupling with a corresponding connector of a next adjacent assembly. Additionally, a mechanism is provided to restrain movement of the next adjacent assembly prior to full engagement with the first assembly to enable performance of a desired preparation procedure.

  • Patent number: 7398822
    Abstract: A technique is provided in which a contraction joint is used to facilitate connection of well equipment assemblies at a downhole location. The contraction joint accommodates changes in system length during engagement and use or the well equipment assemblies in a wellbore. Additionally, the contraction joint provides a positive indication of joint position and enables resetting of the joint following initial contraction.
