A tubular handling system can include a bridge disposed in a horizontal orientation above a horizontal storage area, a tubular lift system that can transport a tubular in a horizontal orientation between the horizontal storage area and an intermediate storage location, and a pipe handler, moveably coupled to the bridge, that can transport the tubular between the intermediate storage location and a rig floor. Also provided is a method for handling tubulars that can include operations of delivering or retrieving a tubular in a vertical orientation to or from a rig floor, transporting the tubular between the rig floor and a bridge, rotating the tubular between vertical and horizontal, retrieving or delivering the tubular to an intermediate storage location, and raising or lowering the tubular between the intermediate storage location and a horizontal storage area while maintaining the tubular in the horizontal orientation.

Robotic pipe handler systems

A pipe handling system for transporting pipe between a horizontal storage location and a rig floor, where the pipe handling system can include an adjustable length ramp assembly which can be adjusted by installing one or more extension sections between bottom and top sections The sections can include interfacing features that can align the sections with each other when they are attached together in the ramp assembly.

Adjustable pipe handling system

A pipe handling system that can include a base skid, a ramp rotationally attached to the base skid, and support equipment (e.g., a drag chain pan, or equipment skid) coupled to the ramp, wherein rotation of the ramp from a first deployed position to a first stowed position lifts the support equipment from a second deployed position to a second stowed position. A method can include rotating the ramp relative to the base skid from a first deployed position to a first stowed position, and simultaneously lifting support equipment relative to the base skid from a second deployed position to a second stowed position in response to rotating the ramp.

A technique facilitates use of a liner hanger in a wide variety of environments by distributing loading. The liner hanger may comprise a liner hanger cone, e.g. an annular cone body, having a plurality of slots for receiving corresponding pipe-gripping slips. The slip slots and the corresponding pipe-gripping slips are staggered both longitudinally and circumferentially to distribute loading. An actuator may be used to shift the slips into gripping engagement with a surrounding pipe, e.g. casing, to improve the load distribution on the surrounding pipe and liner hanger cone once the liner is supported.

A technique facilitates actuation and use of a liner hanger in a wide variety of environments. Depending on the application, the liner hanger may be conveyed downhole within a casing located in a wellbore. The liner hanger comprises slips which may be set against the casing by applying a pressurized fluid through a liner hanger port to a liner hanger actuator. After the slips are set, the liner hanger may be actuated to form a metal-to-metal seal which blocks further fluid flow through the port, thus isolating the port during subsequent downhole operations.

A technique facilitates hanging of a liner in a borehole. According to the technique, a liner hanger and a liner may be deployed downhole into a borehole. A wellbore anchoring device of the liner hanger is initially actuated to engage a surrounding surface and to resist downward movement of the liner. Additionally, a hold down anchor is subsequently actuated to resist upward movement of the liner. The hold down anchor may be released via mechanical manipulation of the liner hanger.

Method and apparatus for bi-directionally anchoring a liner in a borehole

A technique facilitates joining of sections of tubing and related monitoring. An expandable tubular member may be coupled with an external tubing, e.g. a casing. The expandable tubular member is deployed into the external tubing to a desired position. Then, an expandable portion of the expandable tubular member may be plastically deformed in a radially outward direction and into engagement with the external tubing. A sensor system may be combined with the expandable tubular member to monitor a characteristic of the expandable tubular member.
