Patent number: 11767728Abstract: A plug for displacing cement in a downhole environment comprising a seal surface having at least one profile. The seal surface, in response to applied pressure, creates a hydraulic seal with another device. The seal surface can be made of molded rubber and the profile formed thereon can be formed from the molded rubber and during the molding process. The profile can be a semicircular profile or multiple semicircular profiles. The profile or profiles can be one or more semicircular profiles and one or more line profiles. The plug can be a bottom plug and the seal surface can be an upstream seal surface and the other device can be a float collar. The plug can be a top plug and the seal surface can an upstream seal surface and the other device can be a bottom plug.Type: GrantFiled: July 15, 2019Date of Patent: September 26, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Avinash Gopal Dharne, Lonnie Carl Helms

Patent number: 11566489Abstract: A stage cementing tool has a mandrel defining a central flow passage and a plurality of fully open cement flow ports. A packer disposed about the mandrel is movable from an unset to a set position. An opening sleeve is movable in the mandrel from a closed position to an open position in which the flow ports are exposed to allow flow therethrough. The opening sleeve is operable to move the setting sleeve to set the packer against the wellbore as it moves in the mandrel from the closed to the open position.Type: GrantFiled: April 29, 2021Date of Patent: January 31, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Ishwar Dilip Patil, Lonnie Carl Helms, Avinash Gopal Dharne, Frank Vinicio Acosta, Priyanshkumar Prashantkumar Desai

Patent number: 11519242Abstract: A stage cementing tool has a mandrel defining a central flow passage and a plurality of cementing passages in a wall thereof. A packer is disposed about the mandrel. A closing sleeve is detachably connected to and movable relative to the mandrel. An opening sleeve defining a plurality of fully open cement flow ports therethrough is telescopically movable relative to the closing sleeve and movable relative to the mandrel. The opening sleeve is movable to move the packer to the set position, and thereafter movable to open a cement flow path between the central flow passage and an annulus defined by the stage cementing tool and the wellbore.Type: GrantFiled: April 30, 2021Date of Patent: December 6, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Avinash Gopal Dharne, Lonnie Carl Helms, Ishwar Dilip Patil, Frank Vinicio Acosta

Patent number: 11293260Abstract: A buoyancy assist tool has an outer case and a rupture disk connected in the outer case. A sleeve is disposed in the outer case and movable from first to second position in the outer case. A rupture disk membrane of a rupture disk prevents the sleeve from moving to the second position prior to the rupture disk membrane rupturing. The outer case is configured to be connected in a well casing. A lock ring holds the sleeve in the first position.Type: GrantFiled: December 20, 2018Date of Patent: April 5, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Avinash Gopal Dharne, Stephen Allen Yeldell, Frank Vinicio Acosta, Min Mark Yuan, Kevin Wendell Ardoin
