Patent number: 12278087Abstract: Methods and systems for creating attachments between a sample manipulator and a sample within a charged particle systems are disclosed herein. Methods include translating a sample manipulator so that it is proximate to a sample, and milling portions of the sample manipulator such that portions are removed. The portion of the sample manipulator proximate to the sample is composed of a high sputter yield material, and the high sputter yield material may be the material milled with the charged particle beam such that it is removed from the sample manipulator. According to the present disclosure, the portions of the sample manipulator are milled such that at least some of the removed high sputter yield material redeposits to form an attachment between the sample manipulator and the sample.Type: GrantFiled: March 26, 2024Date of Patent: April 15, 2025Assignee: FEI CompanyInventors: Christopher Thompson, Dustin Ellis, Adam Stokes, Ronald Kelley, Cedric Bouchet-Marquis

Patent number: 11959370Abstract: A valve assembly for integration within a wellbore string disposed within a hydrocarbon-containing reservoir is provided. The valve assembly includes a valve housing having a plurality of frac ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a bottom sleeve operatively mounted within the valve housing configured to selectively open the frac ports, and a top sleeve operatively mounted within the valve housing slidable between (i) a first position defining a first fluid pathway whereby fluid is flowable down into the central passage and into the reservoir via the frac ports, and (ii) a tracing position defining a second fluid pathway whereby fluid is flowable from the reservoir into an annulus defined between the top sleeve and the housing. The valve assembly also has a tracer compartment defined within the annulus forming part of the second fluid pathway and accommodating a tracer material.Type: GrantFiled: April 24, 2020Date of Patent: April 16, 2024Assignees: NCS MULTISTAGE INC., NCS MULTISTAGE, LLC., REPEAT PRECISION, LLC.Inventors: Dustin Ellis, Shan Zi, John Ravensbergen, Craig Harty, Brock Gillis, Stanley Mberia, Anna Cruse, Rio Whyte

Patent number: 11078753Abstract: A wellbore apparatus to control the flow of fluids into the wellbore, comprising: a housing; a passage disposed within the housing; a flow communicator for allowing communication into the passage; a flow control member; and frangible members releasably retaining the flow control member to the housing in a retained position, and configured, while the apparatus is disposed in an operative orientation, for becoming fractured in response to application of a force in a downhole direction to release the flow control member from the housing such that the flow control member becomes displaceable relative to the flow communicator; wherein: the flow communicator and the flow control member are configured such that, while the apparatus is disposed in the operative orientation within the wellbore, the flow control member is disposed uphole relative to the retained position while the flow communicator is disposed in the open condition.Type: GrantFiled: September 15, 2017Date of Patent: August 3, 2021Assignee: NCS Multistage Inc.Inventors: Michael John Werries, Rio Whyte, Dustin Ellis

Publication number: 20070007014Abstract: An actuator operatively coupled to a wellbore tool is activated upon receiving fluid that a predetermined applied pressure. When the fluid string reaches the predetermined applied pressure, the actuator undertakes a specified action such as longitudinal movement, rotation, expansion, etc. that actuates or operates the wellbore tool. Premature actuation of the wellbore tool is prevented by applying a resistive force to the actuator that, alone or in cooperation with another mechanism, arrests movement of the actuator. This resistive force is generated by applied pressure of the fluid in the work string.Type: ApplicationFiled: July 7, 2005Publication date: January 11, 2007Applicant: Baker Hughes IncorporatedInventors: James Sessions, David Saucier, Dustin Ellis
