Patent number: 11542756Abstract: A system for providing information through a metal wall employs a device adapted to be arranged on one side of the metal wall and a magnetic-permeability element, provided at, near or connected to the device. The magnetic-permeability element is based on a material having a relative magnetic permeability of at least 2000. The disclosure also provides use of said system. The use may involve the step of optimizing the magnetic-permeability element using equivalent inductive mass (EIm). The system can for example be used to magnetically sense the location of a cable present on the outside of a wellbore tubular using a magnetic orienting tool that is located within the wellbore tubular.Type: GrantFiled: April 22, 2021Date of Patent: January 3, 2023Assignee: SHELL USA, INC.Inventors: Dhruv Arora, Matheus Norbertus Baaijens, Stephen Palmer Hirshblond, Derrick Melanson, Brian Kelly McCoy

Patent number: 10920581Abstract: A flow velocity meter, for measuring flow velocity of a fluid, has a distributed acoustic sensor along aq longitudinal direction, which has a distributed sensing element. The distributed sensing element is acoustically coupled to a distributed fluid-contact surface via a distributed acoustic path extending between the distributed fluid-contact surface and the distributed sensing element. Moreover the distributed acoustic path is fully bypassing the fluid. At least a part of the fluid-contact surface is provided with a flow-disturbing surface texture having a surface relief with a pre-determined pattern in said longitudinal direction. Acoustic flow noise, emitted as a result of the fluid flowing along and in contact with the flow-disturbing surface texture, is picked up by the distributed sensing element as a distributed acoustic signal.Type: GrantFiled: June 30, 2017Date of Patent: February 16, 2021Assignee: SHELL OIL COMPANYInventors: Dhruv Arora, Matheus Norbertus Baaijens, Stephen Palmer Hirshblond
