  • Patent number: 10656614
    Abstract: A tool management system includes a plurality of individual tool retention units that are in electronic communication with a central webserver. Each tool retention unit is designed to independently monitor a designated toolset and transmit tool use data to the webserver. The data compiled by the webserver can be routinely evaluated to ensure proper accountability of all tools within a particular workspace. Due to the autonomous nature of each unit, subsets of tools within a larger monitored collection can be added, removed or replaced without disruption of monitoring amongst the remainder of tools. In one embodiment, a tool retention unit is constructed as a chest comprising a plurality of individual, swappable drawers housed within a common frame. In use, each drawer is provided with a controller that is configured to monitor its designated toolset and transmit any tool-related data to a main controller in communication with the webserver.

  • Patent number: 10544651
    Abstract: A system including a downhole device coupled to a pressure balanced setting tool. The setting tool may be pressure balanced to lock a setting piston in place as the system is deployed into a well. That is, in spite of downhole well pressures, no substantial differential may emerge between the setting piston and the annular space of the well adjacent the system. Thus, the setting piston may remain locked in place until triggered for setting. This may include breaching a rupture disc of another piston to disrupt hydraulic communication between the setting piston and the annular space. This allows subsequent triggering, for example through another breach of a rupture disc defining a volumetric chamber, to take place in a manner that allows stroking of the setting piston. In this way, the setting tool may be utilized to achieve setting of the downhole device.

The design can use a V-shape where the vertex is toward the mandrel and the legs are oriented toward the surrounding tubular. The legs in that instance can be thicker than the vertex thickness to aid in folding while providing enhanced strength at the surrounding tubular where shear forces apply as a result of seal compression against the surrounding tubular. The design features a single or multiple vertices that are similarly aligned or alternatingly oppositely aligned to create a zigzag shape in cross-section. Material selection can vary with the expected service conditions.

    Abstract: The present invention relates to a millable plugging device for use in a well pipe. The device includes an inner mandrel and an outer housing provided radially outside at least parts of the inner mandrel. A sealing assembly is provided radially outside the inner mandrel, where the sealing assembly is configured to be brought from a run state to a set state by a relative axial displacement between the inner mandrel and the outer housing. The millable plugging device has a first center axis and the second mandrel section has a second center axis which is displaced parallel in relation to the first center axis. Rotation of the inner mandrel in the set state is bringing a third mandrel section of the mandrel to a locked state, in which further rotation of the inner mandrel is prevented.

  • Patent number: 9695659
    Abstract: Certain aspects of the present disclosure are directed to tools actuated by pipe swell. A downhole assembly for a wellbore may be provided. The downhole assembly can include a first sleeve and a second sleeve. The first sleeve can expand from a first position to a second position in response to a first pressure applied to the first sleeve. The first sleeve can contract to the first position in response to a cessation of the first pressure. The second sleeve can be positioned adjacent to the first sleeve to define a swell chamber. The swell chamber can actuate a downhole tool by a pressure stored in the swell chamber by the expansion of the first sleeve.

  • Patent number: 9593546
    Abstract: Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.

  • Patent number: 9562411
    Abstract: A packer for a well comprises a seal element and seal setting apparatus. The seal setting apparatus is moveable with respect to the seal element in a setting direction to apply a setting force to the seal element to move the seal element from a run-in configuration to a set configuration in which the seal element forms a contact seal with a conduit wall. The packer is arranged such that, in the set configuration, a pressure differential across the packer, which creates a force in the setting direction, will increase the setting force applied by the seal setting apparatus to the seal element to maintain the seal.

  • Patent number: 9523256
    Abstract: A fold back ring for a swell packer is disclosed. A swell packer has a support member, a swellable element coupled to the support member, and a fold back ring coupled to the support member and engaging the swellable element. The fold back ring is sized and positioned such that when the swellable element swells, the fold back ring flexes outwardly and is caught between the swellable element and the interior surface of the well. The fold back ring therefore forms a barrier against extrusion of the swellable element.
