Patent number: 11920412Abstract: A device and method used for inspecting and measuring coiled tubing, production tubing or drill pipe as it enters the well. Defects such as internal and external wall loss, cracking and deformation can be detected and quantified. The axial motion of the tubing can be measured allowing for depth measurements that are more accurate and reliable than what can be obtained using an encoder wheel system.Type: GrantFiled: August 5, 2020Date of Patent: March 5, 2024Assignee: DarkVision Technologies Inc.Inventor: Graham Manders

Publication number: 20230358131Abstract: A device and method used to inspect wellbores, cased or uncased using cameras. Improvements in downhole optical imaging are provided using telecentric lens, prisms and mirrors, or structured lighting. Stereoscopic arrangements and ultrasound sensor may provide 3D or contour information. The images are stored on the tool and analyzed later. The present tool overcomes the deficiencies currently experience by downhole camera operators, such as poor scale and perspective.Type: ApplicationFiled: March 10, 2023Publication date: November 9, 2023Inventors: Timothy Luu, Graham Manders, Damian Nesbitt

Patent number: 11725497Abstract: A device and method for manipulating a robotic end effector in a well. Actuators manipulate the end effector independently through multiple degrees of freedom to improve the perspective of the end effector. An imaging sensor may be used to image, measure and identify features of a well and objects located therein. The sensor may be an ultrasound transducer, camera or x-ray sensor arranged radially, axial or distributed over a 2D surface. The end effector may be connected to a tool, such as a fishing tool, a welder, a milling tool, or a repair tool.Type: GrantFiled: August 13, 2019Date of Patent: August 15, 2023Assignee: DarkVision Technologies IncInventors: Michael Halpenny-Mason, Matt James, Graham Manders

Patent number: 11644441Abstract: A system, device and method for imaging, measuring and identifying surface features in a tubular, such as a casing, wellbore, or pipe. The device comprises an ultrasound transducer for sonifying an area of the surface of the tubular, with a pulse intercepting axial locations of the sonified area at different times. Reflected signals are processed using their time of flight to interpret the reflected signals as axial locations of features on the surface of the tubular. Multiple sonified areas are partially overlapped in the axial direction to capture features redundantly. Reflections from the multiple areas are combined to remove noise and strengthen reflections from real features. A geometric model of the surface of the tubular is rendered and displayed. Capturing larger areas per frame increases the logging rate and oversampling improves the resolution and signal to noise ratio.Type: GrantFiled: February 5, 2020Date of Patent: May 9, 2023Assignee: DarkVision Technologies IncInventors: Graham Manders, Michael Halpenny-Mason

Patent number: 11578591Abstract: A device and method used to correct beamforming of an acoustic phased array in cases of eccentricity of the acoustic device in a tubular. A processor calculates the eccentricity from multiple scan lines and create a geometric model of a well or pipe relative to the device. The processor may correct each scan line's focus and/or angle of incidence at a surface of the well or pipe based on the observed eccentricity.Type: GrantFiled: December 9, 2019Date of Patent: February 14, 2023Assignee: DARKVISION TECHNOLOGIES INCInventor: Graham Manders

Patent number: 11573341Abstract: A device and method used to increase the resolution when imaging, measuring and inspecting wells, pipes and objects located therein. The device comprises an array of acoustic transducers that both transmit and receive acoustic signals. Scan lines may be overlapped by interlacing transmission and receiving windows thus increasing either the resolution or logging speed drastically compared to conventional approaches. The sequence of the scan lines making up an imaging frame is created by stratifying physically close lines and randomly selecting from within each stratum, preventing interference from neighboring transducers, signals and acoustic artifacts that fundamentally limit logging speed and resolution using conventional methods.Type: GrantFiled: October 15, 2019Date of Patent: February 7, 2023Assignee: DARKVISION TECHNOLOGIES INCInventors: Graham Manders, Michael Halpenny-Mason

Publication number: 20220339670Abstract: An acoustic transducer array and method of making same. A first metal layer is deposited on a first side of a piezoelectric composite to form a common electrode and a second metal layer is provided over the obverse side. Portions of the second metal layer are removed to create a plurality of individual electrodes. A third metal layer may be deposited onto the plurality of individual electrodes, the third metal layer being thicker than the second metal layer. The individual electrodes extend beyond the piezoelectric composite in the elevation direction to create electrode leads. Metal layers may be provided by lithography, a wireframe or a foil sheet.Type: ApplicationFiled: October 13, 2020Publication date: October 27, 2022Applicant: DarkVision Technologies IncInventors: Jay HOPE, Graham MANDERS, Connor VANDENBERG, Jacob William ROSE
