The downhole system can include a tool body, a source of ferrofluid, and a magnet. The magnet can magnetically couple with the ferrofluid from the source for arranging the ferrofluid adjacent to the tool body for isolating an object positioned in a wellbore from effects of fluids present in the wellbore.Type: GrantFiled: December 30, 2013Date of Patent: February 20, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Burkay Donderici, Baris Guner, George David Goodman, Wesley Neil Ludwig

Patent number: 9869155Abstract: Methods and systems directed to controlling the rheology of settable compositions in subterranean formations. Embodiments include a method of controlling the rheology of a set-delayed cement composition, the method comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder; shearing the set-delayed cement composition in an amount sufficient to substantially prevent solids settling; storing the set-delayed cement in a pumpable fluid state for at least 1 day; activating the set-delayed cement composition; introducing the set-delayed cement composition into a subterranean formation; and allowing the set-delayed cement composition to set in the subterranean formation. Additional methods and systems are also provided.Type: GrantFiled: September 9, 2013Date of Patent: January 16, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Thomas Jason Pisklak, Samuel J. Lewis, Kyriacos Agapiou, Peter James Bou, Pauline Akinyi Otieno, Lance Everett Brothers, Ronnie Glen Morgan

Patent number: 9840659Abstract: Methods including deactivation and activation of permeability modifiers for use in subterranean formation operations. A first treatment fluid may be introduced into a subterranean formation having a first treatment zone having a first aqueous permeability value, the first treatment fluid comprising a first aqueous base fluid and a deactivated permeability modifier. The deactivated permeability modifier may be adsorbed onto a surface of the first treatment zone. A second treatment may thereafter be introduced into the subterranean formation, the second treatment fluid comprising a second aqueous base fluid and a cyclodextrin compound. The second treatment fluid may contact the deactivated permeability modifier to activate the permeability modifier by complexing the deactivating surfactant with the cyclodextrin compound, thereby forming an activated permeability modifier adsorbed onto the surface of the first treatment zone and reducing the aqueous permeability of the first treatment zone.Type: GrantFiled: February 2, 2015Date of Patent: December 12, 2017Assignee: Halliburton Energy Services, Inc.Inventors: B. Raghava Reddy, Anindya Ghosh, Antonio Recio, III, Larry S. Eoff, Christopher A. Lewis

Patent number: 9797222Abstract: A tool for enhancing or directing magnetic fields using ferrofluids in a downhole system is provided. The downhole system can include a tool body, a source of ferrofluid, and a positioning magnet. The positioning magnet can magnetically couple with the ferrofluid from the source for enhancing or directing a magnetic field through at least a portion of an annulus between the tool body and a wellbore formation.Type: GrantFiled: December 30, 2013Date of Patent: October 24, 2017Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: George David Goodman, Burkay Donderici, Baris Guner

Patent number: 9783727Abstract: Methods and systems including introducing a treatment fluid into a subterranean formation, wherein the treatment fluid comprises a base fluid and a fluid loss control package (FLCP). The FLCP comprises rigid non-degradable particulates and pliable degradable particulates. The FLCP forms a fluidic seal in the subterranean formation at a target interval, thereby providing fluid loss control therein.Type: GrantFiled: October 22, 2015Date of Patent: October 10, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Matthew Lewis Lahman, Philip D. Nguyen, Janette Cortez, Jessica Lynn Heeter
