  • Patent number: 10439375
    Abstract: Assemblies and methods of use are disclosed for repairing the coating of a coated wellbore line. A wellbore line can be cleaned and then coated with a repair material before being pulled through a die to shape the coating and then being pulled through setting section to set the repair material. The repair material can be a thermoplastic material that is set by cooling, or a thermoset material that is set by heating. The wellbore line can be repaired upon exiting a wellbore or being unspooled from a reel.

  • Patent number: 10358883
    Abstract: A downhole tool assembly includes a downhole tool and an anchor. The anchor is positionable at a downhole work site and includes a wet-connect port for engaging a battery pack. The tool operates until the battery runs low on power, when a low battery power alert is activated. The tool may be anchored at the work site while the battery is disconnected and retrieved to the surface for replacement. One or more charged batteries are then deployed and connected to the tool without having to remove the tool from the worksite or reposition the tool. The tool may be coupled to a wireline cable or a slickline cable or coiled tubing having a conductive wire for delivering low-voltage power to the tool. While the low-voltage power may not be adequate to operate the tool at full load, the power may be used to charge the tool during downtime.

  • Patent number: 10294743
    Abstract: The disclosure provides a downhole anchoring apparatus for use in a downhole tool. An example downhole anchoring apparatus may include a housing with a hub provided within the housing. The hub may be arranged to rotate in a bidirectional fashion about a longitudinal axis. The downhole anchoring apparatus may also include a deployment linkage. The deployment linkage may be coupled to the hub by a hinge so that when the hub is rotated in a first direction, a distal end of the deployment linkage is extended radially outward from the central axis, and when the hub is rotated in a second direction, the distal end of the deployment linkage is retracted toward the central axis.

  • Publication number: 20190003267
    Abstract: A chain of bend-limiter segments is coupled together. The chain has a first end and a second end. The chain is bendable such that an angle between the first end and the second end is at least N degrees and a radius of curvature of the chain is at least M. A cable is inserted through the chain from the first end to the second end. The chain and the cable are coupled to a tool. The tool is pulled using the cable. The chain maintains a radius of curvature of the cable greater than M and prevents a stress level in the cable from exceeding a yield point.

  • Patent number: 10073005
    Abstract: In some embodiments, a distributed nondestructive inspection method for slickline cable structural defect detection transmits a light pulse along an optical waveguide in the slickline cable. A reflected light signal is 5 received from the optical waveguide in response to the light pulse. Defects can then be determined in the slickline cable based on variations in scattering intensity, phase shift, specific spectral signature, power spectral density, strain amplitude, and/or transmission loss of the reflected light signal as compared to the light pulse.

  • Patent number: 9939347
    Abstract: Disclosed embodiments include a distributed nondestructive inspection method and system for slickline cable structural defect and mechanical strength degradation inspection. One method may include transmitting a light pulse along an optical fiber embedded in a slickline cable. A reflected light signal is received from the optical fiber in response to the local strain induced refractive index variation. Defects and mechanical strength degradation may be determined by time-dependent time-domain and frequency-domain data analyses of the dynamic strain signals and power spectral density variation as a function of time and cable location.

  • Publication number: 20170133124
    Abstract: In accordance with embodiments of the present disclosure, a cable system for conveying well servicing equipment into a wellbore includes a core support structure extending longitudinally along an axis of the cable system. The core support structure comprises polymer reinforced with fibers, and the fibers are oriented substantially parallel to the axis of the cable system. The cable system also includes a mesh layer disposed around and bonded to the core support structure. The mesh layer includes metal wrapped around the core support structure. The cable system also includes a polymeric coating disposed around and bonded to the mesh layer. The mesh layer enables increased structural support of the cable system, particularly against forces in the radial direction relative to the axis of the cable system. In some applications, the mesh layer acts as a return conductive path for conductors embedded in the core support structure.

  • Patent number: 9587442
    Abstract: An automated locking joint can include a first member, a second member, a joint, a locking structure, and a positioning device. The joint can connect the first member with the second member. The second member can be pivotable about the joint relative to the first member. The locking structure can be positionable between a lock position that prevents pivoting of the second member about the joint and an unlock position that allows pivoting of the second member about the joint. The positioning device can automatically move the locking structure from the lock position to the unlock position or from the unlock position to the lock position.

  • Patent number: 9557212
    Abstract: In accordance with embodiments of the present disclosure, systems and methods for determining a dynamic effective elastic modulus of a composite slickline or wireline cable are provided. A system for estimating the effective elastic modulus (or change thereof) may include a sensing head assembly, a vibration generator, a pair of pulleys, and an optical-based signal processing assembly. The system may detect a resonant frequency of a section of the composite cable held between the two pulleys and estimate the effective elastic modulus based on the detected resonant frequency variation. Adjustments for weight and length of the cable extending into the wellbore may be made as well to determine the dynamic elastic modulus of the cable. The opto-mechanical integrated system described below may enable real-time elastic modulus determination.
