Truck container with secure side-entry compartment

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.

A packer () for establishing sealing engagement with a surface disposed in a wellbore includes a packer mandrel () and a seal assembly () slidably disposed about the packer mandrel (). The seal assembly () has a running position and a radially expanded sealing position. A piston () is slidably disposed about the packer mandrel () and operably associated with the seal assembly (). A release assemblyis disposed about the packer mandrel () and is releasably coupled to the piston () such that actuation of the release assembly () decouples the release assembly () from the piston () allowing the piston () to shift longitudinally relative to the packer mandrel () to operate the seal assembly () from the running position to the radially expanded sealing position, thereby setting the packer ().

A packer () for establishing sealing engagement with a surface disposed in a wellbore includes a packer mandrel () and a seal assembly () slidably disposed about the packer mandrel (). The seal assembly () has a running position and a radially expanded sealing position. A piston () is slidably disposed about the packer mandrel () and operably associated with the seal assembly (). A collet assemblyis disposed about the packer mandrel () and is releasably coupled to the piston () such that radially inwardly shifting at least portion of the collet assembly () decouples the collet assembly () from the piston () allowing the piston () to shift longitudinally relative to the packer mandrel () which operates the seal assembly () from the running position to the radially expanded sealing position, thereby setting the packer ().

An apparatus for actuating a downhole tool within a well bore comprises a cylindrical mandrel extending longitudinally through the downhole tool; an interventionless, hydrostatic, top-down actuating piston disposed about the mandrel and forming a first chamber and a second chamber therebetween; and a rupture disk that prevents fluid communication between the well bore and the first chamber until sufficient hydrostatic pressure is applied to the well bore to fail the rupture disk. A method of actuating a downhole tool comprises connecting a top-down actuating module to the downhole tool, running the downhole tool to a desired depth within a well bore, pressuring up the well bore without pressuring up an internal flow bore extending through the top-down actuating module, hydrostatically actuating an upper piston of the top-down actuating module to exert an actuation force onto the downhole tool, and actuating the downhole tool.
