US Patent:

20100153241, Jun 17, 2010

Filed:

Dec 12, 2008

Appl. No.:

12/333965

Inventors:

Randy Rucker - Houston TX, US
Lisa Rivers - Katy TX, US
Brian Lochhead - Houston TX, US
David Nguyen - Sugar Land TX, US

Assignee:

PAYMETRIC, INC. - Houston TX

International Classification:

G06Q 10/00

US Classification:

705 30

Abstract:

A system and method for reconciling transaction data, including identifying one or more transactions to be reconciled; aggregating one or more potential matching purchase orders; and creating a proposal that identifies one or more purchase orders that may correlate to the transaction to be reconciled, wherein creating a proposal comprises performing one or more search iterations to identify one or more purchase orders that fit within one or more parameters of the search iterations.

US Patent:

57224994, Mar 3, 1998

Filed:

Aug 22, 1995

Appl. No.:

8/518037

Inventors:

David M. Nguyen - Houston TX
Michael A. Siracki - The Woodlands TX
Stephen G. Southland - Humble TX

Assignee:

Smith International, Inc. - Houston TX

International Classification:

E21B 1046

US Classification:

175431

Abstract:

An improved polycrystalline diamond composite ("PDC") cutter comprises a single or a plurality of secondary PDC cutting surfaces in addition to a primary PDC cutting surface. The two cutting surfaces are spaced apart, resulting in enhanced cutter efficiency and useful life. The primary PDC cutting surface is a polycrystalline diamond layer on an exposed end face of the cutter. A secondary cutting surface is formed by a polycrystalline diamond layer embedded within the body of the cutter. The secondary cutting surface can have a larger diameter than the primary cutting surface so that the forward end of the cutter parallels rock formation during drilling and both cutting surfaces engage the rock formation.

International Classification:

G01D 2100
E21B 1202
E21B 1204

US Classification:

116208

Abstract:

A wear indicator is provided for a rotary drilling tool of the type which comprises a bit body having a leading surface for cutting, abrading or reaming a hole in a target substrate material such as a sub-surface formation, the wear indicator comprising or including one or more discrete areas of a visually distinct material to that from which the drilling tool is mainly composed, the visually distinct material being arranged or configured at or adjacent the surface of the bit such that progressive wear of the bit and hence the or each visually distinct discrete area provides a visual indication of surface wear of the tool.

US Patent:

Filed:

Feb 23, 1990

Appl. No.:

7/484406

Inventors:

Robert B. Coolidge - Spring TX
David M. Nguyen - Houston TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 1046

US Classification:

175329

Abstract:

A cutting element retention system is shown for a diamond drill bit. The drill bit has a bit body with a bit face, the bit face having polycrystalline diamond cutting elements received thereon within mating recesses provided in the face. Each cutting element has a mounting body with a leading face and a trailing face and a diamond layer carried on the leading face. At least one fin with associated troughs are located behind the mounting body on the bit face or within the carrier substrate or cutting element itself and arranged transverse to the cutting element layer. The fins are separated by a trough which extends for substantially the entire cross-sectional depth of the diamond cutting face.

Inventors:

David M. Nguyen - Houston TX

Assignee:

Hughes Tool Company - USA - Houston TX

International Classification:

E21B 1060

US Classification:

175393

Abstract:

An improved earth boring bit of the type having diamond cutting elements and a fluid passageway to direct drilling fluid toward a borehole bottom during drilling, a metal nozzle with a cylindrical, threaded exterior and a noncircular throat having a minimum cross sectional dimension to receive a mating wrench and a length to resist damage from the torque required to make-up and break-out the nozzle for threads in the body of the bit.

David M. Nguyen - Houston TX

Assignee:

Hughes Tool Company-USA - Houston TX

International Classification:

E21B 1036

US Classification:

175409

Abstract:

A matrix bit is shown of the type having a metallic mandrel with a connecting end for connection in a well pipe string leading to the well surface. An opposite end is covered with a cast matrix material which defines a central bit body. A plurality of integral blades are formed of the cast matrix material and extend axially and radially from the central bit body. Each of the blades is reinforced by a metallic extension which is contained within the matrix material and extends coaxially with each blade.
