Patent number: 11959341Abstract: The low friction wireline standoff improves wireline cable performance during borehole logging operations. The use of low friction wireline standoffs ameliorates the effects of wireline cable differential sticking, wireline cable key-seating, and high wireline cable drags, by reducing or eliminating contact of the wireline cable with the borehole wall during the logging operation. The low friction wireline standoff comprises external wheels mounted on two finned half shells that clamp onto the wireline with precision cable inserts which are manufactured to fit a wide range of logging cables. The wheels reduce the cable drag down-hole resulting in lower surface logging tensions, aiding conveyance in deep and deviated wells.Type: GrantFiled: September 30, 2021Date of Patent: April 16, 2024Inventors: Guy Wheater, Stuart Huyton

Patent number: 11898434Abstract: A wellbore depth instrument (WDI) for measuring wellbore depths along a wellbore, acting as an odometer. In one embodiment, the WDI may be mounted onto a downhole tool-string deployed by a pipe, coil, e-line, or slickline. Further, the WDI may comprise two independently suspended wheels of fixed diameter with respective internal electronic packages that each may record in memory rotations of their respective wheels and frequencies of those rotations along the wellbore. Such recordings may allow for accurate determination and characterization of tool-string dynamics (e.g., tool-string speed, direction, stick slip, creep and hold-ups) as well as absolute and relative tool-string position along a wellbore (i.e., wellbore depth).Type: GrantFiled: July 8, 2022Date of Patent: February 13, 2024Inventors: Guy Wheater, Stuart Huyton

Patent number: 11851963Abstract: The articulated wireline hole finder is a modular device which attaches to the bottom of a wireline logging tool-string to aid conveyance down irregular shaped and/or deviated boreholes which possess features such as ledges, washouts, and contractions, that might otherwise terminate full descent of the tool-string to the bottom of the borehole and thereby compromise the wireline data acquisition objectives. Elements of the articulated wireline hole finder may include a low friction roller nose assembly and spacer sub, an articulated spring joint, that transfers tool-string weight and directs lateral movement of the roller nose towards hole center, and a pair of five arm centralizers that possess a wide dynamic range.Type: GrantFiled: September 27, 2021Date of Patent: December 26, 2023Inventors: Guy Wheater, Stuart Huyton

Publication number: 20220127920Abstract: The present invention relates to a wireline cased-hole roller (WCRO) for deployment during a logging operation that reduces slickline or e-line cable contact and drag in the cased hole section of a wellbore. Arrays of WCROs, clamped on the slickline or e-line, reduce logging tensions and improve force transmission from surface down to the tool cable head by significantly reducing the cased-hole cable drag. They also permit the use of lower grade cables or winches in certain environments due to lower logging tensions. Another benefit is the mitigation of cased hole cable wear zones since the cable is suspended above the casing, liner or tubing. In high-angle or horizontal wells, arrays of WCROs aid conveyance and improve tractor performance by reducing the cable drag force which has to be overcome to reach the target zone.Type: ApplicationFiled: October 26, 2020Publication date: April 28, 2022Inventors: Guy Wheater, Stuart Huyton
