  • Patent number: 10301902
    Abstract: Apparatuses and methods for an anti-preset and anti-reset mechanism for a retrievable packer are disclosed herein. These features may be used to prevent the packer from being actuated prematurely during deployment downhole and to prevent the packer from re-actuating during retrieval. An apparatus may include a mandrel, a slip assembly disposed about the mandrel, a collet member disposed about the mandrel and adjacent to the slip assembly, and a cover sleeve disposed about the mandrel and coupled to the collet member. A method for releasing a packer may include cutting a mandrel, sliding a cover sleeve and a collet member having a collet lug downhole with respect to the mandrel, applying force from the collet member to the slip assembly, disengaging the slip assembly from a well casing, and engaging an inner surface of the collet lug to a protrusion on the mandrel.

  • Patent number: 7594763
    Abstract: A fiber optic delivery system and side pocket mandrel removal system. In one example, a system for making optical connections in a well includes an optical connector positioned in the well, and another optical connector displaceable into operative connection with the first optical connector after the first optical connector is positioned in the well. In another example, a method of making optical connections in a well includes the steps of: positioning a tubular string in the well; then installing an assembly in the tubular string, the assembly including an optical connector; and then displacing the optical connector into operative engagement with another optical connector in the tubular string.
