Patent number: 11643893Abstract: An anchor for securing a well tool can include a longitudinally extending central axis, an outwardly extendable grip member, and a mechanical linkage including multiple pivotably connected links. The links pivot relative to each other in a plane laterally offset from the central axis. A method of anchoring a well tool can include flowing a fluid through an anchor connected to the well tool, thereby outwardly extending a grip member into contact with a well surface, and applying a tensile force to the anchor, thereby increasingly biasing the grip member against the well surface and securing the well tool relative to the well surface. A method of anchoring a tubing cutter in a tubular string can include applying a tensile force from an anchor to the tubular string, and cutting the tubular string while the tensile force is applied from the anchor to the tubular string.Type: GrantFiled: June 27, 2022Date of Patent: May 9, 2023Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventor: Justin R.

Patent number: 11111745Abstract: A well tool can include a downhole anchor with at least one outwardly extendable slip including longitudinally spaced apart grip structures, and a longitudinally extending beam which connects the grip structures to each other. The beam has a radial thickness which is greater than a lateral width of the beam. A slip retainer retains the slip, and a spring inwardly biases the slip relative to the slip retainer. The spring surrounds the slip and the slip retainer. An area moment of inertia of the beam with respect to a lateral axis through a centroid of the beam is greater than an area moment of inertia of the beam with respect to a radial axis through the centroid of the beam.Type: GrantFiled: July 12, 2019Date of Patent: September 7, 2021Assignee: Weatherford Technology Holdings, LLCInventor: Justin R.

Patent number: 11008826Abstract: An inflatable packer assembly can include an inflatable seal element having an internal inflation chamber, a flow passage extending longitudinally through the inflatable packer assembly, a flow restrictor between sections of the flow passage, and a flow controller that selectively permits and prevents fluid communication between the inflation chamber and each of the flow passage sections. The flow controller changes from a deflate configuration to an inflate configuration in response to an increase in flow rate through the flow passage. A method can include connecting an inflatable packer assembly in a tubular string, so that a longitudinal flow passage of the tubular string extends through the inflatable packer assembly, and a flow restrictor restricts flow between sections of the flow passage, and inflating an inflatable seal element of the inflatable packer assembly while fluid flows between the flow passage sections via the flow restrictor.Type: GrantFiled: May 17, 2019Date of Patent: May 18, 2021Assignee: Weatherford Technology Holdings, LLCInventor: Justin R.

Patent number: 10760372Abstract: A well tool can include an annular seal and a radial expansion mechanism having radially retracted and radially expanded configurations, the annular seal being longitudinally displaceable relative to the radial expansion mechanism in the radially retracted configuration. A method of setting a well tool can include positioning the well tool in a well, the well tool including an annular seal and a radial expansion mechanism, and then longitudinally displacing the annular seal to a radially outward position relative to the radial expansion mechanism. A well system can include a well tool including an annular seal, a radial expansion mechanism, an inner mandrel assembly and a setting sleeve, and a setting tool that produces a relative longitudinal displacement between the setting sleeve and the inner mandrel assembly, the annular seal radially outwardly overlying the radial expansion mechanism in response to the relative longitudinal displacement.Type: GrantFiled: December 19, 2018Date of Patent: September 1, 2020Assignee: Weatherford Technology Holdings, LLCInventors: Justin R.
