Publication number: 20240141750Abstract: There is a downhole valve for use in a standpipe. A valve body defines a flow path through the valve body. A valve poppet within the valve body is axially movable in a direction parallel with the standpipe when in use. An electrically activated linear activation system is connected to the valve poppet to move the valve poppet axially. The flow through the flow path varies as the valve poppet is moved axially. There is a method of activating a downhole valve for use in a standpipe. A condition downhole is detected using a sensor. The downhole valve is electrically activated based on the detected condition downhole. The valve and method may be used to turn on and off a vibration tool when a drill string is in the horizontal section of a well.Type: ApplicationFiled: March 3, 2023Publication date: May 2, 2024Inventors: Hartley Randle, Brandon Jullion, Joshua Gamble

Publication number: 20230130532Abstract: A sealed bearing system has a pressure-retaining seal separating two lubricating chambers, one pressure balanced to the outside and the other pressure balanced to the inside. The pressure retaining seal may be a non pumping seal. Radial bearings may be mounted near either axial side of the seal to prevent deflection. The pressure-retaining seal may include a flange and the flange may be axially compressed between a seal carrier and a portion of an outer tubular to fix the seal to the outer tubular. The seal and seal carrier may be installed using a mandrel on which they are temporarily positioned in order to insert and install them into the outer tubular.Type: ApplicationFiled: September 30, 2022Publication date: April 27, 2023Inventors: Hartley Randle, Brandon Jullion, Alaric Tomas, Joshua Gamble

Patent number: 11085241Abstract: Provided is an adjustable split thrust ring and a drilling system including the same. The adjustable split thrust ring, in one embodiment, includes a downhole split ring including two or more separate downhole pieces, the two or more separate downhole pieces fitting together to form a substantially circular downhole shoulder surrounding a substantially circular driveshaft. The adjustable split thrust ring further includes an uphole split ring positionable proximate the downhole split ring and including two or more separate uphole pieces, the two or more separate uphole pieces fitting together to form a substantially circular uphole shoulder surrounding the substantially circular driveshaft. In this embodiment, the substantially circular downhole shoulder and the substantially circular uphole shoulder are movable relative to one another to adjust to fit a groove in a driveshaft that they are configured to sit.Type: GrantFiled: March 9, 2017Date of Patent: August 10, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Hartley Randle, Brandon Jullion, Gustav Edward Lange, Alben D'Silva, Kennedy John Kirkhope

Patent number: 10961781Abstract: Anti-rotation pad assemblies are provided for restraining rotation of a non-rotating housing in geologic drilling system. The anti-rotation pad assemblies include extensible members, which extend from an internal cavity in the anti-rotation pad assemblies and are capable of engaging a wellbore wall. The extensible members may include rollers that are biased radially outwardly to engage the wellbore wall such that the anti-rotation pad assemblies may move axially within the wellbore while restraining the non-rotating housing in a particular rotational orientation. Flow ports are defined in the anti-rotation pad assemblies to encourage mud flow through the internal cavity, and thereby discourage the accumulation and solidification of drilling fluids around the extensible members. The extensible members thus remain free to move under the bias of a biasing mechanism within the internal cavity and can thus effectively maintain the rotational orientation of the non-rotating housing in the wellbore.Type: GrantFiled: November 4, 2016Date of Patent: March 30, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Akshay G.
