Patent number: 11970939Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for machine learning analysis of low-frequency signal data in fracturing operations. The present technology can receive strain data associated with a monitoring well that is proximate to a treatment well. The strain data can comprise information representing a fracturing operation associated with the treatment well. Further, the present technology can convert the strain data into image data where a color scale corresponds to a degree of strain observed by a fiber optic cable deployed in the monitoring well. As follows, the present technology can provide the image data to a machine-learning model, which is configured to identify one or more features in the image data.Type: GrantFiled: July 15, 2022Date of Patent: April 30, 2024Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Benjamin Schaeffer, Mikko K.

Patent number: 11247291Abstract: The disclosed technology generally relates to welding, and more particularly to a consumable welding wire for metal arc welding, and a method and a system for metal arc welding using the consumable welding wire. In one aspect, a method of arc welding includes providing a welding wire comprising one or more alkaline earth metal elements. The method additionally includes applying power to the welding wire to generate a plasma arc sufficient to melt the welding wire. The method further includes depositing molten droplets formed by melting the welding wire onto a workpiece at a high deposition rate while regulating to maintain a substantially constant power delivered to the plasma arc.Type: GrantFiled: May 16, 2018Date of Patent: February 15, 2022Assignee: LINCOLN GLOBAL, INC.Inventors: John Benjamin Schaeffer, Steven R. Peters, Badri K. Narayanan, Yen-Chih Liao

Patent number: 10702942Abstract: An arc welder produces a weave pattern between workpieces. Each weld run comprises a center portion including a joining region between the workpieces and edge regions spaced apart from the joining region. The welder includes a power source that provides a welding waveform to a welding electrode to generate an arc to achieve a desired heat for welding, a welding torch, and an oscillator for oscillating the torch between the welding edge regions. A controller causes the power source to operate in a first mode utilizing a first waveform during welding within the joining region, and in a second mode using a second waveform, having a greater positive component than the first waveform, during welding within the edge regions. The controller determines a stickout value based on the first waveform but not the second waveform, and performs seam tracking based the second waveform but not the first waveform.Type: GrantFiled: March 30, 2017Date of Patent: July 7, 2020Assignee: LINCOLN GLOBAL, INC.Inventors: Steven R.

Publication number: 20170125987Abstract: A separating and/or insulation removal device for a cable-processing machine has at least two knife blocks that can be moved in opposite directions, each with at least one knife. A cable that is to be cut to length and/or is to have its insulation removed can be guided between the knives, which are actuated by at least one drive for at least one of the knife blocks, and a mechanism for purposes of guiding at least the driven knife block in the direction towards the cable. The drive acts at least indirectly on an element of the mechanism. Each driven knife block sits on a lever at a distance from its lever axis and executes a pivotal movement along a circular arc. For this purpose, the drive engages with the lever via a rotatable force transmission element at a distance from the lever axis and the knife block.Type: ApplicationFiled: November 2, 2016Publication date: May 4, 2017Applicant: Schleuniger Holding AGInventors: Sebastian BRAUN, Benjamin SCHÄFFER
