Publication number: 20240151340Abstract: A closure for pipelines carrying a fluid under pressure, the closure includes at one or more seals located on a vertical sealing face of the barrel collar along a leak pathway between a horizontal sealing face of the barrel collar and an ambient environment. In some embodiments, the horizontal sealing face includes a primary seal. The one or more seals are adapted to prevent the escape of fluids having a lower molecular weight than that of the main pipeline product or fluid contained by the closure, and is arranged to alter a path of a leak pathway to the ambient environment and to cause at a pressure drop across the one or more seals. The closure may also include a leak check valve for blowdown.Type: ApplicationFiled: October 30, 2023Publication date: May 9, 2024Inventors: Roger L. Poe, Jon Maslen, Kolton Landreth, Jed Hightower

Publication number: 20240110656Abstract: A completion system includes a pipeline fitting; a plug body sized for the fitting; a set of blades adapted for securing the plug body within the fitting, the blades having a retracted position and an extended position; a circumferential groove adapted to receive the set blades when in the extended position; and a control bar adapted for use with the plug body. The completion system of this disclosure further includes a sensor and the set of blades is adapted to trigger the sensor when the blades are a properly fully extended to a locking position in the circumferential groove, indicating the plug body is in a properly locked position, and to not trigger the sensor when the blades are not fully extended into the circumferential groove to their proper depth. In some embodiments, the sensor indicates a closed electrical circuit. In other embodiments, the sensor indicates a magnetic flux.Type: ApplicationFiled: September 29, 2023Publication date: April 4, 2024Inventors: Jon Maslen, Roger L. Poe

Patent number: 11873938Abstract: A pipeline pigging element (10) that changes its size in an axial and a radial direction as a function of applied pipeline pressure. The pigging element includes at least two circumferential zones (13, 15) having different section modulus than one another, each of the zones changing at different rates from one another between an uninflated and an inflated state at the applied pipeline pressure. The pigging element reacts to changes in pipe geometry, having a first length and a first diameter at a first applied pipeline pressure and a second length and a second diameter different than the first at a second applied pipeline pressure. As the pigging element wears, it becomes easier to inflate at the applied pressure and sealing contact with the pipe wall remains substantially unaffected. No onboard pumps or fluid circuits are required to inflate the pigging element.Type: GrantFiled: March 24, 2021Date of Patent: January 16, 2024Assignee: TDW Delaware, Inc.Inventors: Roger L. Poe, Matt Logan, John R. Morrow, Charles G. Boellstorff

Publication number: 20230279980Abstract: Embodiments of a plugging tool (10) of this disclosure a control bar head (20) and at least one sealing head (30, 40) pivotally connected to the control bar head, the control bar head including a stress suppressor (50) located at a lower end (25) of the control bar head, the stress suppressor including an elastomeric element (51). The stress suppressor can act as a dual-stage suppressor, there being a primary (first stage) and a secondary (second stage) stress suppressor or zone (50A, 50B). The primary stress suppressor has an arched-shaped lowermost end (58) located between a pair of spaced-apart feet (21) of the control bar head, the feet having lateral edges (23) and comprising the secondary stress suppressor. During rotation of the tool into the pipe, stress to the pipe is reduced in a range of 5X to 14X relative to a plugging tool without the stress suppressor.Type: ApplicationFiled: March 3, 2023Publication date: September 7, 2023Inventors: Roger L.

Patent number: 11686408Abstract: A system and method for detecting passage of a pipeline pig, the system and method including a passive impulse detector (10) having a housing (13); a non-intrusive connection (15) of the housing to an exterior wall (17) of a pipeline (P), at least one vibration sensor (11) housed by the housing, and signal processing (23) including at least one band pass filter (27) configured to receive data collected by the vibration sensor, the vibration sensor and band pass filter configured to monitor frequencies in a predetermined range indicating a series of impulses caused by start-and-stop movement of the pipeline pig. The selected frequencies should be those more easily detectable above the baseline (signature or natural resonance) frequency of the section of pipeline being monitored. In some embodiments, the selected frequencies are lower frequencies. No portion of the passive pipeline pig signal intrudes into an interior of the pipeline.Type: GrantFiled: November 22, 2021Date of Patent: June 27, 2023Assignee: TDW Delaware, Inc.Inventor: Roger L. Poe

Patent number: 11536414Abstract: A pig trap of this disclosure may include one or more injectors or nozzles located along a sidewall of the barrel and oriented to deliver a jet of fluid toward a back side of a vertical member of a pig or tool. The nozzle may be part of an assembly that includes a longitudinally extending pipe having a flat-profile flange at an inlet end, a curved-profile flange at the nozzle end, and a bend in between the two ends. When the assembly is installed in a sidewall opening of a pig trap, the nozzle delivers a jet of fluid toward the back side of a vertical member of the pig. A leak path may be provided through flanges or formed between the sidewall opening and a periphery of the curved-profile flange. Launch forces of more than 10 to 15 times that of a conventional launcher may be achieved.Type: GrantFiled: October 12, 2020Date of Patent: December 27, 2022Assignee: TDW Delaware, Inc.Inventors: Roger L.

Publication number: 20220325844Abstract: A re-settable pipeline gauging tool (10) of this disclosure includes a cylindrical tool body (11) that includes a deformable portion (13) with a plurality of sensors (25) located near or on an external circumferential surface (12) of the deformable portion. A sealed unit (60) contains a corresponding signal source (25). Pipeline gauging relies upon the compressibility and elasticity inherent in the deformable portion as it encounters anomalies in pipeline geometry and moves between a first size and a second size, the signal strength of the source detected by the sensors changing as a result. The sensors may be arrayed in a circumferential band (47) about the deformable portion or along its length. In some embodiments, the sensors and source are magnetic or acoustic (e.g., transceivers or radar integrated chips). In other embodiments, the sensors and source are light or fiber optic.Type: ApplicationFiled: March 21, 2022Publication date: October 13, 2022Inventors: Roger L. Poe, Ed Maynard, Joseph Alan Morton
