Patent number: 8230926Abstract: A cementing tool for cementing a casing in a well has an inner mandrel that defines a central flow passage and has at least one fluid port defined through a wall thereof. An outer mandrel is disposed about the inner mandrel and the inner and outer mandrels define an annular space therebetween. The outer mandrel has at least one sealing element affixed thereto. An opening sleeve is positioned in the inner mandrel and is movable from a closed position to an open position in which the fluid port is uncovered. An expansion cone is positioned in the annular space. Fluid pressure applied through the central flow passage, and the fluid port will pass into the annular space and will urge the expansion cone through the annular space which will plastically deform the outer mandrel so that sealing elements affixed to the outer mandrel engage a previously installed casing in the well to seal thereagainst.Type: GrantFiled: March 11, 2010Date of Patent: July 31, 2012Assignee: Halliburton Energy Services Inc.Inventors: Henry E. Rogers, Steven L. Holden, Alan T. Jackson

Patent number: 7694732Abstract: The present invention relates to a diverter tool used in a pipe string to lower a liner into a partially cased wellbore. The diverter tool has a diverter body that defines a longitudinal central flow passage and has diverter ports defined therethrough to communicate and redirect fluids received in the liner to an annulus between the diverter tool in casing previously set in the wellbore. The diverter tool has first and second closure members. The first closure member is movable between open and closed positions on the diverter body. The second closure member is detachably connected in the diverter body in its open position and is movable to its closed position to prevent flow through the diverter ports.Type: GrantFiled: December 3, 2004Date of Patent: April 13, 2010Assignee: Halliburton Energy Services, Inc.Inventors: Henry E. Rogers, Nicholas C. Braun, Steven L. Holden

Patent number: 7533729Abstract: A regulating valve assembly for regulating fluid flow through a passage, the assembly having: a back-flow valve comprising a seat and a closure element, wherein the closure element engages with the seat in a closed configuration and disengages from the seat in an open configuration; a lock in mechanical communication with the back-flow valve to lock the backflow valve in the open configuration; and a forward-flow valve in mechanical communication with the lock and comprising a seat and a closure element, wherein the closure element engages with the seat in a closed configuration and disengages from the seat in an open configuration.Type: GrantFiled: November 1, 2005Date of Patent: May 19, 2009Assignee: Halliburton Energy Services, Inc.Inventors: Henry E. Rogers, Steven L. Holden, David D. Szarka

Patent number: 7322432Abstract: The present invention relates to a diverter tool used in a pipe string used to lower a liner and a cutting apparatus on the end thereof into a partially cased wellbore. The diverter tool has a diverter body that defines a longitudinal flow passage and has the diverter ports defined therethrough to communicate a drilling fluid displaced through the pipe string into the liner into an annular space around the diverter tool. The diverter tool has a closure member so that when the wellbore is drilled to its desired depth, the diverter ports through which drilling fluid is diverted may be closed and the liner may be cemented in the wellbore.Type: GrantFiled: December 3, 2004Date of Patent: January 29, 2008Assignee: Halliburton Energy Services, Inc.Inventors: Henry E. Rogers, Nicholas C. Braun, Steven L. Holden

Patent number: 6896051Abstract: An apparatus for preventing or limiting the rotation of cementing plugs in a casing string during drillout. The apparatus includes an outer housing with a sleeve disposed therein. The sleeve has an inner surface configured to engage cementing plugs received therein to cause an interference fit. The sleeve will hold the cementing plugs when rotational forces, such as drilling forces, are applied so that during drillout, rotation of the cementing plug is prevented or is at least limited.Type: GrantFiled: January 15, 2004Date of Patent: May 24, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Earl D. Webb, Michael D. Stevens, Steven L. Holden

Patent number: 5494103Abstract: A well jetting apparatus for use in fracturing of a well. Fracture initiation is provided by forming openings through the well casing and then forming fan-shaped slots in the formation surrounding the casing. Those slots are formed by a the jetting apparatus which has at least one hydraulic jet directed through the opening. The apparatus may be pivoted generally about the point of the opening to form the slots, but preferrably a plurality of slots are formed substantially simultaneously. These fan-shaped slots circumscribe an angle about the axis of the casing substantially greater than the angle circumscribed by the opening itself through which the slot was formed. These techniques are particularly applicable to fracturing of horizontal wells, but the apparatus may be used in any well configuration.Type: GrantFiled: June 16, 1994Date of Patent: February 27, 1996Assignee: Halliburton CompanyInventors: Jim B. Surjaatmadja, Steven L. Holden, David D. Szarka
