Patent number: 11512561Abstract: A junction for use in a multilateral completion system is presented. The junction comprises a metal sealant applicable to a lateral component of the multilateral completion system. The metal sealant is expanding in response to hydrolysis and after activation forms a seal and an anchor with a well casing or tubing of the multilateral completion system. The metal sealant is expanding in response to one of an alkaline earth metal hydrolysis and a transition metal hydrolysis. More specifically, the metal sealant is expanding in response to one of magnesium hydrolysis, aluminum hydrolysis, calcium hydrolysis, and calcium oxide hydrolysis.Type: GrantFiled: February 22, 2019Date of Patent: November 29, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Michael Linley Fripp, Mark C.

Patent number: 11098560Abstract: A tool, system, and method for reentry access into a lateral wellbore. The tool, utilized in the system and the method, can include a body with an internal flow passage, an inflatable bladder disposed along an exterior portion of the body, and a flow restrictor that can partially restrict fluid flow through the internal flow passage and create a pressure differential across the tool when fluid pressure rises at an inlet of the internal flow passage. The pressure differential can cause inflation of the inflatable bladder and a surface of the inflatable bladder can be extended radially outward from the body in response to the inflation, where the extended surface can push the tool away from a wall of a main wellbore toward an opposite wall of the main wellbore and divert the tool into a lateral wellbore.Type: GrantFiled: November 13, 2017Date of Patent: August 24, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventor: Mark C.

Patent number: 10954735Abstract: This disclosure may generally relate to drilling operations and, more particularly, to systems and methods for sidetracking an existing well. Specifically, examples of the present disclosure may include creating a window by introducing a pH-modifying fluid downhole to degrade a portion of a casing string, thereby creating the window through which a secondary wellbore may be drilled. A method for creating a window in an oilfield tubular may comprise of providing a pH-modifying fluid in the oilfield tubular disposed in a wellbore and contacting a degradable section of the oilfield tubular with the pH-modifying fluid to degrade at least a portion of the degradable section and form an exit window in the oilfield tubular.Type: GrantFiled: September 14, 2018Date of Patent: March 23, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Michael Linley Fripp, Mark C.

Patent number: 10883313Abstract: Systems and methods are described for drilling a new secondary wellbore from a primary wellbore in which a production string is already deployed. The production string is severed below a desired kick-off location for the new secondary wellbore and the upstream portion of the production string is withdrawn from the primary wellbore, thereby exposing an end of the remaining production string. A lateral orientation device (LOD) is mounted on the exposed end of the production string. The LOD includes a shoulder for seating on the exposed end, anchoring mechanism(s) to secure the LOD to adjacent tubular(s), and seals to sealingly engage adjacent tubulars. The LOD may include a contoured surface for orientation of a tool, such as a whipstock, which may be utilized to drill a new wellbore. Alternatively, a work string may be coupled with the LOD to perform pumping operations in the wellbore below the LOD.Type: GrantFiled: October 19, 2016Date of Patent: January 5, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: David Joe Steele, Clifford Lynn Talley, Doug Durst, Mark C.

Patent number: 10619438Abstract: It may be required at a well site to create a lateral wellbore from a primary wellbore. A dissolvable whipstock assembly may be positioned within a primary wellbore to deflect a mill or drill bit to create a secondary wellbore. The dissolvable whipstock assembly may include a wear plate coupled to a whipstock. The wear plate comprises an incline or ramp to deflect a mill or drill to a casing exit or pre-milled window to create the secondary wellbore. The wear plate comprises a material that is strong enough to withstand the force applied by the drilling and is degradable or dissolvable. Any one or more components of the whipstock may be dissolvable such that at least a portion of the whipstock dissolves to form a pathway through any remaining portion of the dissolvable whipstock and the primary wellbore.Type: GrantFiled: December 2, 2016Date of Patent: April 14, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Michael Linley Fripp, Mark C.

Patent number: 10309179Abstract: A pulling tool deploys on a workstring to retrieving a well component, such as casing or a liner, stuck downhole. The tool has an anchor, a puller, and an implement. The implement is supported on the end of the puller and engages the component. Hydraulic pressure supplied downhole moves at least one puller piston coupled to the implement along a piston mandrel to pull the implement and component. An anchor mandrel coupled to the workstring and the piston mandrel anchors the pulling tool downhole. The anchor has slips disposed on the anchor mandrel that engage in surrounding casing when an anchor piston disposed on the anchor mandrel is hydraulically actuated with the communicated pressure.Type: GrantFiled: September 11, 2015Date of Patent: June 4, 2019Assignee: Weatherford Technology Holdings, LLCInventors: Mark C.

Patent number: 10006264Abstract: A whipstock assembly has a whip, a packer, and an anchor. The packer connects between the whip and the anchor and sets after the anchor is set. The anchor can be set mechanically or hydraulically. To communicate hydraulic pressure to the hydraulically-set anchor, the packer can have an internal bypass for communicating fluid or for passing a hydraulic line from the whip to the anchor. The packer is set mechanically with set down weight applied from the whip via a setting tool or the like. The packer sets eccentrically in the casing and acts as a fulcrum to push the tip of the whip against the inside of the casing.Type: GrantFiled: May 22, 2015Date of Patent: June 26, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Mark C.
