Patent number: 11933133Abstract: A technique facilitates actuation of a packer to a sealing and gripping position along a borehole. The packer includes a packer element structure mounted about a center structure. The packer element structure includes a sealing element mounted along an expandable base such that the sealing element may be radially expanded. Additionally, the packer includes an actuator member connected to a portion of the packer element structure via a release mechanism, e.g. a shear member. A plurality of slips may be located on the actuator member such that linear movement of the actuator member causes successive movement of the packer sealing element and then the slips in the radially outward direction. The packer may be constructed such that this sequential setting motion creates a jarring effect to ensure the slips securely bite into the surrounding wellbore surface, e.g. casing surface.Type: GrantFiled: October 20, 2020Date of Patent: March 19, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Farhan Ahmed Omer, Susan Wu, Thomas Eric Dudley, Yiming Fan, Weiming Lan, Nitin Verroju

Patent number: 11543587Abstract: A Mach-Zehnder interferometer (MZI) filter comprising one or more passive compensation structures are described. The passive compensation structures yield MZI filters that are intrinsically tolerant to perturbations in waveguide dimensions and/or other ambient conditions. The use of n+1 waveguide widths can mitigate n different sources of perturbation to the filter. The use of at least three different waveguide widths for each Mach-Zehnder waveguide can alleviate sensitivity of filter performance to random width or temperature variations. A tolerance compensation portion is positioned between a first coupler section and a second coupler section, wherein the tolerance compensation portion includes a first compensation section having a second width, a second compensation section having a third width and a third compensation section having a fourth width, wherein the fourth width is greater than the third width and the third width is greater than the second width.Type: GrantFiled: June 11, 2021Date of Patent: January 3, 2023Assignee: PSIQUANTUM, CORP.Inventors: Koustuban Ravi, Mark Thompson, Eric Dudley
