US Patent:

51542307, Oct 13, 1992

Filed:

Dec 17, 1991

Appl. No.:

7/808866

Inventors:

John M. Dees - Richardson TX

Assignee:

Oryx Energy Company - Dallas TX

International Classification:

E21B 33138
E21B 4312

US Classification:

166277

Abstract:

In a well treatment method, a fluid is positioned in a wellbore have formation perforations in alignment with the portion thereof to be treated. A gas generator is positioned in proximity with the fluid and is actuated to disperse the fluid within the wellbore in accordance with a pressure/time relationship. In the preferred embodiment of the invention, the fluid is a fluid resin material which is polymerized following operation of the gas generator to form a consolidated, porous, permeable matrix which retains sand and other fine materials while permitting the flow of production fluid into the well.

Filed:

Jan 24, 1992

Appl. No.:

7/825040

Inventors:

John M. Dees - Richardson TX
William J. Begnaud - Kingwood TX
Nancy L. Sahr - Montgomery TX

Assignee:

Oryx Energy Company - Dallas TX

International Classification:

E21B 33138

US Classification:

166295

Abstract:

A method for diverting resins and other treating fluids used for sand control in wells drilled through unconsolidated subterranean formations is provided. Explosives placed in the wellbore in proximity to the treating solutions are actuated to divert the solutions through all perforations in the casing of the well and allow sand-free production of fluids through the well.

US Patent:

6089864, Jul 18, 2000

Filed:

Feb 1, 1999

Appl. No.:

9/243340

Inventors:

Randall R. Buckner - Houston TX
John D. Dees - Houston TX
William L. Hintermister - Conroe TX

International Classification:

A61C 900

US Classification:

433 71

Abstract:

A diagnostic and therapeutic apparatus for use in the evaluation, detection, and treatment of humans that suffer from chronic grinding of the teeth known as "bruxing. " The apparatus includes a pressure sensor contained in a mouth piece and electronic for detecting activation of the sensor due to bruxing and for generating an human cognizable output in response to bruxing. The apparatus can also include electronics for storing and analyzing human bruxing activities.

Filed:

Feb 11, 1992

Appl. No.:

7/834888

Inventors:

Mark A. Peavy - Plano TX
John M. Dees - Richardson TX

Assignee:

Oryx Energy Company - Dallas TX

International Classification:

E21B 3313
E21B 4312

US Classification:

166286

Abstract:

A method for plugging and unplugging the slots or openings in slotted liners in wells is provided. A resin is coated onto the slotted liner by using an explosive to disperse the resin from an elongated container onto the surrounding slotted liner.

US Patent:

51782189, Jan 12, 1993

Filed:

Jun 19, 1991

Appl. No.:

7/718346

Inventors:

John M. Dees - Richardson TX

Assignee:

Oryx Energy Company - Dallas TX

International Classification:

E21B 33138
E21B 4326
E21B 43263

US Classification:

166281

Abstract:

Methods are provided for chemically consolidating subterranean formations around wells using resins. Resins are forced into the formations by high pressures instantaneously applied when perforations are formed in casing in wells or when pressures are released from tubing in wells. Perforating, explosives or gas generators may be used in addition to the high pressures for driving resins into formations. The resins are polymerized to form permeable consolidated zones around wells.

Assignee:

Oryx Energy Company - Dallas TX

International Classification:

E21B 4326
E21B 43116
E21B 43267

US Classification:

166308

Abstract:

A method if disclosed for decreasing the flow resistance of a subterranean formation surrounding a well. A high fluid pressure is suddenly applied to the formation and fluid is pumped into the high pressure fractures. The fluid may contain proppant particles.
