A woven sleeve includes a tubular member that includes circumferentially oriented fibers and axially oriented fibers. The tubular member is configured to adjust between a relaxed state in which the tubular member is positioned around a well tool and an extended state in which the tubular member is in tight contact with an outer surface of the well tool across substantially an entire inner surface of the tubular member to limit an extent to which the well tool can expand radially outward.

Woven sleeves and related methods of constraining a well tool

Disclosed are perturbation signaling systems and methods for use in a downhole well. Such systems can include a downhole tool configured to hang from a wellbore anchoring mechanism. The tool can have or associate with an energy harvesting system, a power management system, a sensing system, and a wireless communication system. A turbine generator can encode signals into flowing fluid through electric load and related changes in hydraulic energy, transmitting information through the fluid. A receiver station positioned at another well location can decode and or relay the signals. Signals can bypass impediments such as noise zones by inducing signals in adjacent parallel well environments such as an annulus. The receiver station can accumulate energy from repeated redundant signaling over time to enhance communication and signal resolution. An additional wireless communication system can receive and/or relay data to a remote location.

Method and apparatus for wireless communication in wells using fluid flow perturbations

A method for measuring the thickness of casing in a wellbore and/or analyzing the inner surface of the cased or non-cased wellbore. The method includes an positioning an untethered logging tool in a drill string, receiving the logging tool in a catcher positioned within the drill string, positioning a plurality of ultrasonic transducers with the average distance between the outer surface of the plurality of transducers and an interior surface of the catcher sub being less than 0.8 mm, and moving the drill string and the logging tool toward a mouth of the borehole while transmitting acoustic waves through the catcher sub toward the wellbore casing and receiving acoustic waves back to the logging tool after the acoustic waves interact with the wellbore casing and reflect through the catcher.

Method and apparatus of untethered casing and bore hole survey through the drill string while tripping out drill pipe

A system including a bottom hole assembly and a ram positioned below a barrier of a well and methods for deploying the same are described. The ram is configured to secure the bottom hole assembly at an end of the bottom hole assembly to secure the bottom hole assembly within the well.

Bottomhole assembly deployment

An assembly and a method for entering a lateral branch of a main wellbore through a lateral window with an assembly are described. The assembly includes an arm coupled to a body. The arm positions the body to enter the lateral branch. The assembly includes an actuator to actuate the arm relative to the body. The assembly includes a first sensor, a second sensor, and a controller. The first sensor senses a condition of the arm and transmit the condition of the arm to the controller. The second sensor senses when the assembly is located in the main wellbore or the lateral branch transmits the location to the controller. Responsive to either the first signal or the second signal, the controller actuates the arm relative to the body to position the body to enter the lateral window and determines when the assembly has entered the lateral branch.

Entering a lateral branch of a wellbore with an assembly

Downhole equipment and surface equipment communicate wirelessly with each other. A signal wirelessly transmitted at a first frequency from a downhole controller disposed within a wellbore is received at a surface location. The received signal is demodulated to a demodulated digital value. The demodulated value is added to an end of a buffer string. The buffer string is processed to determine whether the buffer string contains a message that is valid. In response to determining that the buffer string contains the message that is valid, the message is decoded. A command signal is wirelessly transmitted at a second frequency different from the first frequency to the downhole controller to adjust a state of the downhole controller.

A system includes a surface sub-system and a downhole sub-system. The surface subsystem includes a pump and a surface valve sub-assembly. The pump is configured to pump a fluid from a container, downhole into a wellbore. The surface valve sub-assembly is fluidically coupled to the pump and configured to receive a first portion of the fluid pumped by the pump. The surface valve sub-assembly includes a dump valve, a surface controller, and a return line. The surface controller is configured to adjust fluid flow through the dump valve, and the return line is configured to flow fluid from the dump valve to the container. The downhole sub-system includes a turbine-generator and a downhole controller coupled to the turbine-generator. The turbine-generator is configured to generate an output in response to receiving a second portion of the fluid pumped by the pump.

A zonal isolation assessment system includes a receiver, production tubing disposed in a wellbore, a zonal isolation assembly, and an assessment assembly. The zonal isolation assembly is fluidically coupled to the production tubing. The zonal isolation assembly includes isolation tubing that flows production fluid from the wellbore to the production tubing, a first sealing element, and a second sealing element to fluidically isolate an internal volume of the isolation tubing from an isolated annulus defined between the isolation tubing and the wall of the wellbore. The assessment assembly includes a first pressure sensor at the internal volume of the isolation tubing configured to sense a first pressure value and a second pressure sensor at the annulus and configured to sense a second pressure value. The assessment assembly transmits to the receiver the first pressure value and the second pressure value to determine the integrity of the zonal isolation assembly.

A well tool includes a deformable liner configured to be positioned within a wellbore. The deformable liner is configured to be deformed radially. The well tool includes a first inflatable packer configured to be positioned within the deformable liner. The first inflatable packer is configured to be inflated while positioned within the deformable liner to deform the deformable liner radially.

A longitudinal length of the expandable mandrel is longer than a longitudinal length of the opening. The expandable mandrel, when actuated, is configured to move in a radial direction with respect to the conduit, such that the portion of the expandable mandrel smaller than the opening moves through the opening and extends beyond the outer surface of the conduit.

The rod passes through the hollow member to couple to the sleeve. The rod is configured to move the sleeve relative to the well tool in response to a pressure applied on the rod. The hollow member defines a seat configured to receive the rod to restrict movement of the sleeve relative to the well tool.
