A conduit inspection tool system includes a conduit inspection tool that includes a body that includes one or more wheels configured to move the body through and in contact with a conduit; at least two power generating sub-systems coupled to the body, each of the at least two power generating sub-systems configured to generate electrical power to operate the one or more wheels to move the body through and in contact with the conduit; and at least one energy storage device electrically coupled to the at least two power generating sub-systems, the at least one energy storage device configured to store electrical power generated by the at least two power generating sub-systems; and a control system communicably coupled to the at least two power generating sub-systems and the at least one energy storage device.

A remote inspection system for inspecting piping that includes: a vehicle configured to move through pipe; a lighting system mounted on the vehicle; a sensor mounted on the vehicle; a communication system on the vehicle; and a processor configured to assess an effective drainage coefficient of the inspected piping based on data gathered from the sensor.

A partially dissolvable plug is to be deployed in a position in a wellbore formed in a subsurface formation. The partially dissolvable plug comprises a first portion comprising a dissolvable material that is to dissolve over time after exposure to a downhole ambient environment in the wellbore and a second portion comprising a non-dissolvable material that is to create a flow restriction as the flow of fluid passes through the partially dissolvable plug. The first portion is to prevent a flow of fluid from downhole to a surface of the wellbore until at least a portion of the dissolvable material is dissolved. A flow rate is to be determined based on a detected change in a downhole attribute that is to change in response to the flow of fluid passing through the partially dissolvable plug after at least a portion of the partially dissolvable plug is dissolved.

A method for performing ultrasonic inspection to a pipe is described, comprising: introducing an in-line inspection tool assembly into a pipe, wherein the in-line inspection tool assembly comprises a gel reservoir and an ultrasonic inspection tool flanked by a pair of batching pigs, wherein the gel reservoir holds a first gel couplant; and driving the in-line inspection tool assembly along the pipe while performing ultrasonic inspection; wherein a gel slug is formed between the pair of batching pigs, and the gel slug facilitates the ultrasonic inspection.

An aquatic in-pipe inspection robot is provided and comprises: means for determining the position of the robot within a pipe and means for adjusting the position of the robot within the pipe, whereby contact with the pipe wall can be avoided; and sensor means for inspecting a pipe.

A pig for use in a pipeline is provided for determining the material of the pipeline in the context of an inline inspection. The pig includes a position determination unit and at least one braking arrangement for immobilizing the pig at a certain position in the pipeline. The pig also includes an X-ray fluorescence sensor.

The present application provides a pipeline structural fault diagnosis apparatus and a diagnosis method. The pipeline structural fault diagnosis apparatus includes a signal generating apparatus configured to generate an acoustic wave signal by knocking a pipeline; a signal collecting apparatus configured to collect the acoustic wave signal; a signal storage apparatus configured to store the acoustic wave signal for a signal processing and analyzing apparatus to analyze and determine a fault type, a fault degree, and a fault position. The acoustic wave signal after being generated by the signal generating apparatus is collected by the signal collecting apparatus and stored in the signal storage apparatus. The signal processing and analyzing apparatus extracts the acoustic wave signal in the signal storage apparatus, and performs processing and analysis to determine the fault type, the fault degree, and the fault position of the pipeline structure.

Embodiments disclosed herein are directed to systems and methods for locating an anomaly along an inside surface of a conveyance pipe containing two mediums separated by a two medium interface. The systems and methods include an assembly transportable within the conveyance pipe. The assembly includes an enclosure that is at least partially transparent and is positionable to be located both above and below the two medium interface. An upper camera and a lower camera enclosed within the enclosure are operable to capture images of the inside surface of the conveyance pipe above and below the two medium interface. A data acquisition unit is in electronic communication with the upper camera and the lower camera, and includes a processor programmed to determine a presence and a location of the anomaly by analyzing the captured images.

Systems for inspecting pipes or cavities including a camera head, a coaxial push-cable, and a video signal transmitter and a communicatively coupled camera control unit (CCU) are disclosed.

A method for restoring video data of a pipe based on computer vision is provided. The method includes: performing gray stretching on pipe image/video collected by a pipe robot; processing noise interference by smoothing filtering; extracting an iron chain from the center of a video image as a template for location; performing target recognition on the center of video data by an SIFT corner detection algorithm; detecting ropes on left and right sides of a target by Hough transform; performing gray covering on the iron chain at the center of the video image and the ropes on two sides; and restoring data by an FMM image restoration algorithm.
