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
