Float Valve Assembly And Method

View page
US Patent:
6497291, Dec 24, 2002
Filed:
Aug 29, 2000
Appl. No.:
09/650204
Inventors:
David D. Szarka - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 3410
US Classification:
166386, 166317, 166387, 166327
Abstract:
An improved float valve according to the present invention includes a packer for positioning within a joint of the casing C while at the surface of the well, the packer including a float valve receptacle therein for at least partially receiving a float valve. The float valve body includes a valve seat and a valve member is positioned for selective engagement and disengagement with the valve seat. A guide nose may be optionally provided for positioning within the casing joint between the valve body and the pin end of the casing joint. The float valve body may be reliably fixed and sealed to the packer body. After the packer setting operation, the casing joint and the packer and the float valve may then be positioned as an assembly within the well.

US Patent:
6547007, Apr 15, 2003
Filed:
Apr 17, 2001
Appl. No.:
09/836755
Inventors:
David D. Szarka - Duncan OK
Henry E. Rogers - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Houston TX
International Classification:
E21B 3410
US Classification:
166317, 166318, 1661774, 166327
Abstract:
A differential float and cementing valve assembly used to position and cement casing in a well bore. A leaf spring and other components of the assembly are preferably constructed of composite materials and/or plastics that can be drilled up with polycrystalline diamond compact (PDC) bits.

Fill Up Tool And Mud Saver For Top Drives

US Patent:
6571876, Jun 3, 2003
Filed:
May 24, 2001
Appl. No.:
09/865089
Inventors:
David D. Szarka - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 3410
US Classification:
166325, 175218
Abstract:
A tubular tool body carried at the end of a drilling rig top drive is received within a drill string being used as a landing string to position casing in a wellbore. External threads on the tool body can be mated with the box threads of the drill string to secure the top drive and drill string together for simultaneous drill string movement and fluid circulation. An annular seal carried about the tool body engages and seals with the internal wall of the drill pipe to prevent drilling fluid leakage when the tool body is received within the drill pipe without thread engagement. The tool has an internal check valve that opens to allow back flow of drilling fluid that may be displaced from the drill pipe as the pipe is lowered into the well. The check valve prevents standing fluid in the top drive from spilling onto the rig floor when the tool is withdrawn from the drill string. Pump pressure applied through the top drive axially moves the check valve against a biasing spring to open a bypass through the wall of the tool to permit forward circulation through the drill string and casing.

Slim Hole Stage Cementer And Method

US Patent:
6651743, Nov 25, 2003
Filed:
May 24, 2001
Appl. No.:
09/864962
Inventors:
David D. Szarka - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 33132
US Classification:
166285, 166291, 166153, 166154, 1661774
Abstract:
A small diameter stage cementer assembly and a hydraulically operated packer collar stage cementer including a cementer housing for interconnection with a casing string positionable in a slim-hole wellbore for a cementing operation. The cementer housing including a seat for receiving a lower, drillable portion of an opening sleeve assembly after the upper drillable portion of the opening sleeve assembly has been drilled out. The lower, drillable portion wedges into engagement with the seat to prevent rotation of the drillable portion during drill-out, such that the lower portion may be drilled up using a small diameter bit and drill string, and accommodating a reduced weight on bit. The packer collar embodiment includes a hydraulically actuatable packer In the packer collar embodiment of the stage cementer cementing ports are provided separate in a separate axial plane from hydraulic inflation ports, such that the secondary opening device or rupture disks may be securely positioned within the cementing ports. Thereby, a relatively thin-walled outer case may be utilized for the hydraulic passageway to the packer without having to increase the case outer diameter to accommodate positioning a rupture disk in the case.

US Patent:
6725935, Apr 27, 2004
Filed:
Jan 29, 2002
Appl. No.:
10/059649
Inventors:
David D. Szarka - Duncan OK
Hank E. Rogers - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 3406
US Classification:
166318, 166327, 1662428
Abstract:
A differential float and cementing valve assembly used to position and cement casing in a wellbore. A leaf spring and other components of the assembly are preferably constructed of composite materials and/or plastics that can be drilled up with polycrystalline diamond compact (PDC) bits. The valve components may be contained within a metallic housing.

Apparatus And Method For Disconnecting A Tail Pipe And Maintaining Fluid Inside A Workstring

View page
US Patent:
6772835, Aug 10, 2004
Filed:
Aug 29, 2002
Appl. No.:
10/230701
Inventors:
Henry E. Rogers - Duncan OK
Michael Dodson - Midland TX
Earl D. Webb - Wilson OK
David D. Szarka - Duncan OK
Frank Acosta - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 1706
US Classification:
1661774, 1662426, 1662427, 166317
Abstract:
An embodiment of a downhole tool for use with a workstring in a wellbore includes a first section, a second section, and a coupling mechanism adapted such that in a first configuration the coupling mechanism couples the first section to the second section. In a second configuration, the coupling mechanism does not couple the first section to the second section. Also disclosed is a method for creating a plug in a wellbore, the method comprising: injecting a slurry into the workstring to form a plug in the wellbore, positioning a flow preventing mechanism into the workstring to prevent fluid flow from exiting the workstring, inducing a coupling mechanism to uncouple a portion of the workstring such that the portion remains with the slurry to create the plug in the wellbore, and removing the first section from the wellbore.

Circulating Cementing Collar And Method

US Patent:
6810958, Nov 2, 2004
Filed:
Dec 20, 2001
Appl. No.:
10/026736
Inventors:
David D. Szarka - Duncan OK
Henry E. Rogers - Duncan OK
Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 3406
US Classification:
166285, 1662428, 166327
Abstract:
An apparatus and method for cementing a casing string in a wellbore. A self-filling tubular cementing collar connected to the lower end of a casing string is provided with one-way flow valving that allows well fluid to enter and self-fill the casing string as it is lowered into the wellbore and automatically prohibits reverse fluid flow from the collar when washing or cementing during forward circulation through the collar. The one-way valving is carried by an axially movable support that can be shifted by a cementing plug moved by pump pressure to permanently seal the entry flow passage after the casing sting is properly positioned in the wellbore.
