  • Publication number: 20240011371
    Abstract: A tool includes a mandrel and at least one gate. The mandrel includes a bore, and the mandrel is able to connect in-line with at least one sand control device of a bottom hole assembly such that the mandrel is coaxial with the at least one sand control device. The mandrel also includes a flow path configuration, such as, at least one flow path connecting the at least one sand control device to the bore, at least one flow path connecting the bore to at least two sand control devices, and at least one flow path connecting the bore to the at least one sand control device and to another device of the bottom hole assembly. The at least one gate has an initial position, and the at least one gate is configured to move from the initial position into a different position to control fluid flow.

  • Patent number: 8220554
    Abstract: Whipstocks and deflectors comprising a degradable composition, and methods of using same are described. A degradable composition may consist essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Methods of using degradable whipstocks in oilfield operations are also described. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. 1.72(b).

  • 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.

  • Publication number: 20080105438
    Abstract: Whipstocks and deflectors comprising a degradable composition, and methods of using same are described. In one embodiment the degradable composition consists essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Methods of using degradable whipstocks in oilfield operations are also described. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure.
