US Patent:

6386300, May 14, 2002

Filed:

Sep 19, 2000

Appl. No.:

09/665586

Inventors:

Harry B. Curlett - Park County WY
David Paul Sharp - Houston TX
Marvin Allen Gregory - Spring TX

Assignee:

Curlett Family Limited Partnership - Cody WY

International Classification:

E21B 716

US Classification:

175 65, 175 67, 175424

Abstract:

A method and system for drilling or cutting a subterranean well or formation using a drilling rig a drill string a plurality of solid material impactors a drilling fluid and a drill bit is disclosed. This invention may have particular utility in drilling wells for the petroleum industry and for cutting formation in the mining and tunnel boring industries. In a preferred embodiment, a plurality of solid material impactors are introduced into the drilling fluid and pumped through the drill string and drill bit to impact the formation ahead of the bit. At the point of impact, a substantial portion by weight of the impactors may have sufficient energy to structurally alter, excavate, and/or fracture the impacted formation. The majority by weight of the plurality of solid material impactors may have a mean diameter of at least 0. 100 inches, and may structurally alter the formation to a depth of at least twice the mean diameter of the particles comprising the impacted formation.

Filed:

Mar 28, 2012

Appl. No.:

13/432206

Inventors:

John L. Maida - Houston TX, US
Etienne M. Samson - Cypress TX, US
David P. Sharp - Houston TX, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

E21B 47/09
E21B 31/06

US Classification:

1662551, 166 665

Abstract:

Fiber optic enabled casing collar locator systems and methods include a wireline sonde or a coil tubing sonde apparatus configured to be conveyed through a casing string by a fiber optic cable. The sonde includes at least one permanent magnet producing a magnetic field that changes in response to passing a collar in the casing string, a coil that receives at least a portion of the magnetic field and provides an electrical signal in response to the changes in the magnetic field, and a light source that responds to the electrical signal to communicate light along an optical fiber to indicate passing collars.

Appl. No.:

13/426414

Inventors:

David P. SHARP - Houston TX, US
John L. Maida - Houston TX, US
Etienne M. Samson - Cypress TX, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

G01V 3/00

US Classification:

3408547

Abstract:

Disclosed are wireline tool systems including a casing collar locator tool and one or more logging tool(s). The logging tool(s) collects information regarding a formation property or a physical condition downhole, and produces a modulated magnetic field to communicate at least some of the collected information. The casing collar locator tool includes a light source and a sensor. The light source transmits light along an optical fiber in accordance with a sensor signal. The sensor produces the sensor signal in response to magnetic field changes attributable to passing collars in a casing string, and to the modulated magnetic field produced by the logging tool(s). Related telemetry methods are also described.

US Patent:

48677760, Sep 19, 1989

Filed:

May 2, 1988

Appl. No.:

7/189295

Inventors:

David P. Sharp - Houston TX

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

C03B 3710

US Classification:

65 2

Abstract:

Apparatus and method for forming an integral structure, such as a lens, on a fiber, such as an optical fiber, which includes a device which imparts centrifugal force to an end of the fiber while the end of the fiber is being heated. An arc or heat source which heats the end of the fiber can both rotate about the longitudinal axis of the fiber and move laterally with respect to the longitudinal axis of the fiber. The apparatus also includes a device for longitudinally moving the fiber relative to the arc. When a fiber is inserted into the apparatus, centrifugal force is exerted on the end of the fiber as the fiber is heated. The fiber is advanced longitudinally relative to the arc until a sphere of a predetermined size is formed. Then, depending upon the shape or lens desired, the sphere may be allowed to cool and be removed from the apparatus, or other operations are performed.

International Classification:

C10J 306

US Classification:

48197R

Abstract:

In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein solid particles containing alkali metal residues are produced in the gasifier or similar reaction zone, alkali metal constitutents are recovered from the particles by withdrawing and passing the particles from the reaction zone to an alkali metal recovery zone in the substantial absence of molecular oxygen and treating the particles in the recovery zone with water or an aqueous solution in the substantial absence of molecular oxygen. The solution formed by treating the particles in the recovery zone will contain water-soluble alkali metal constituents and is recycled to the conversion process where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst. Preventing contact of the particles with oxygen as they are withdrawn from the reaction zone and during treatment in the recovery zone avoids the formation of undesirable alkali metal constituents in the aqueous solution produced in the recovery zone and insures maximum recovery of water-soluble alkali metal constituents from the alkali metal residues.
