Patent number: 11346187Abstract: A well screen for a borehole. The well screen may include an arcuate outer shroud, a mesh layer, and a drainage layer. The arcuate outer shroud may include perforations, a first longitudinal end, and a second longitudinal end. The first and second longitudinal ends may be spaced arcuately apart such that a gap is formed between the first and the second longitudinal ends of the outer shroud. The mesh layer may restrict flow of particulate materials of a predetermined size from passing therethrough and is positioned radially inward from the outer shroud. The mesh layer may include a first and a second longitudinal end that are radially aligned with the first and the second longitudinal ends of the outer shroud to continue the gap. The drainage layer may be positioned radially inward from to the mesh layer and may include at least one of perforations or louvers.Type: GrantFiled: November 7, 2019Date of Patent: May 31, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Stephen Michael Greci, Liam Andrew Aitken, Austin Lee Wright

Patent number: 9580993Abstract: An interventionless downhole screen that is resistant to plugging during run-in-hole operations and a method for remotely actuating the screen. The screen includes a perforated sleeve that is slideably disposed coaxially with a perforated tubular member. When running, the sleeve is in a closed positioned with its openings offset from the apertures in the tubular member, thereby blocking flow through the screened openings, while a check valve through the tubular member allows fluid ingress. To actuate for production, the tubular member is pressurized, which moves a piston into ratcheting engagement with the sleeve. A subsequent depressurization allows the piston to return to its original position, carrying with it the sleeve to an open position where the sleeve and tubing perforations are aligned for allowing fluid flow into the tubular member.Type: GrantFiled: May 10, 2013Date of Patent: February 28, 2017Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventor: Liam Andrew Aitken

Publication number: 20090002563Abstract: Embodiments of a system that includes one or more integrated circuits are described. During operation, the system compensates for gamma correction in a video image to produce a linear relationship between brightness values and an associated brightness of the video image when displayed, where the compensation includes an offset at minimum brightness that is associated with light leakage in a display that is configured to display video images. Then, the system calculates an intensity setting of a light source based on at least a portion of the compensated video image, the light source configured to illuminate the display. Next, the system adjusts the compensated video image so that a product of the intensity setting and a transmittance associated with the adjusted video image approximately equals a product of a previous intensity setting and a transmittance associated with the video image.Type: ApplicationFiled: June 24, 2008Publication date: January 1, 2009Applicant: APPLE INC.Inventors: Ulrich T.
