Cuttings Disposal Method

US Patent:
6752273, Jun 22, 2004
Filed:
Jan 24, 2002
Appl. No.:
10/056931
Inventors:
Jeffrey Reddoch - Lafayette LA
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
B03B 900
US Classification:
209 2, 210768
Abstract:
A novel method for disposing of drill cuttings and more particularly to the process for source identification of such cuttings and the identification of value added processes for commercializing the cuttings in an economical manner. The method of recycling of oil and gas well drill cuttings as disclosed herein begins by identifying drill cuttings by location, type of earth formation and earth strata level from whence extracted, drying, coding and containerizing said cuttings by said grade, mineral type, extraction location, and geological age. Uses for the recycled and graded drill cuttings include graded virgin aggregate for road construction including asphaltic cement, recyclable stone retaining walls and lawn ornaments or other applications useful in landscaping or water drainage control by mixing the dried and refined cuttings with recycled polymer.

Apparatus And Method For Transferring Dry Oil And Gas Well Drill Cuttings

US Patent:
6585115, Jul 1, 2003
Filed:
Nov 28, 2000
Appl. No.:
09/724580
Inventors:
Jeffrey Reddoch - Lafayette LA
Glynn M. Hollier - Aberdeenshire, GB
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
B03B 902
US Classification:
209 3, 209 17, 209 73, 209281, 175 66, 175206, 175207
Abstract:
An apparatus and method for removing and recovering up to 98 percent of the residual drilling mud and fluids from drill cuttings for reuse and storing the drill cuttings in a relatively dry state thereby reducing cuttings volume requirements for storage and transport thereby reducing constipation of the drilling process due to disposal congestion. The present invention further provides methods for collecting and transferring drill cuttings in either dry or wet states to various locations on or adjacent the rig for processing, containerization, transport and disposal, thereby reducing handling and contamination thus simplifying recycling while reducing cost.

Inflatable Windshield Wiper Attachment And Method

US Patent:
6687946, Feb 10, 2004
Filed:
Jan 18, 2001
Appl. No.:
09/766258
Inventors:
Jeffrey Reddoch - Lafayette LA 70598
International Classification:
B60S 128
US Classification:
1525004, 1525041, 152504
Abstract:
A windshield wiper blade attachment with pressurized inflatable scrubbing member. The scrubbing member includes a sustained fluid release delivery system for dispersing a solvent through a polymer matrix or mixed fiber composite material. The scrubbing member further includes a polymeric abrasive textured surface element that aids in effectively scrubbing the windshield. Pressurization of the scrubber is achieved with fluid from the vehicle pressure washer system. System fluid pressure inflates the member in a manner whereby, when it contacts the windshield, the wiper blade is displaced until such time as the scrubbing member loses sufficient fluid by seepage to allow the wiper blade to again make contact with the windshield.

Cuttings Injection System And Method

US Patent:
6640912, Nov 4, 2003
Filed:
Nov 26, 2001
Appl. No.:
09/994522
Inventors:
Jeffrey Reddoch - Lafayette LA
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 2101
US Classification:
175217, 166275, 166308, 166 7515, 166 7512, 3645282, 36452836, 36452839, 3645284
Abstract:
An automated high speed drill cuttings processing and injection module having a relatively small foot print, capable of operation in zone one hazardous environments, for injecting drill cuttings into an earth formation, capable of handling high drilling rate cuttings surges. The process including conveying systems, holding and slurry tanks, circulating pumps, high speed grinding mill, high pressure injection pump, fragmentation system and automation system for controlling electrically driven injection pump having automatic speed control regulation with torque and horsepower limiting features. Thereby allowing high-speed injection without plugging the formation while still allowing for high-pressure formation fracturing when necessary. The processing system further insures cuttings slurry homogenization and entrained particle size to less than 100 micron for both hard and soft particles. The system reduces installation cost dramatically.

Centrifugal Drill Cuttings Drying Apparatus

US Patent:
6763605, Jul 20, 2004
Filed:
May 31, 2002
Appl. No.:
10/161392
Inventors:
Jeffrey Reddoch - Lafayette LA
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
F26B 1724
US Classification:
34 58, 175 66, 175206, 175207
Abstract:
A vertical, centrifugal separator used for drying drill cuttings prior to transport or further processing. The separator is adapted to receive scavenged heat from any source and is further adapted to include internal conveyers, thereby lowering the overall operating profile and providing increased cuttings retention time within a heated environment.

Cuttings Injection System And Method

US Patent:
6321860, Nov 27, 2001
Filed:
Jan 20, 1998
Appl. No.:
9/461604
Inventors:
Jeffrey Reddoch - Lafayette LA
International Classification:
E21B 2100
US Classification:
175206
Abstract:
An automated high speed drill cuttings processing and injection module having a relatively small foot print, capable of operation in zone 1 hazardous environments, for injecting drill cuttings into an earth formation. Capable of handling high drilling rate cuttings surges. The process including conveying systems, holding and slurry tanks, circulating pumps, high speed grinding mill, high pressure injection pump, fragmentation system and automation system for controlling electrically driven injection pump having automatic speed control regulation with torque and horsepower limiting features. Thereby allowing high speed injection without plugging the formation while still allow for high pressure formation fracturing when necessary. The processing system further insures cuttings slurry homogenization and entrained particle size to less than 100 micron for both hard and soft particles. Being unitized the system reduces installation cost dramatically.

Pipe Wiper System

US Patent:
4982787, Jan 8, 1991
Filed:
Jan 2, 1990
Appl. No.:
7/495470
Inventors:
Jeffrey A. Reddoch - Lafayette LA
International Classification:
E21B 3308
US Classification:
166 82
Abstract:
A pipe wiper assembly for stripping fluid from well strings has a container, with side walls, for use above the well head. Inside the container a frame is situated for some limited horizontal movement and the frame contains a pair of wiper blades in a horizontal guideway. The wiper blades move in opposite directions in the guideway between open and closed positions by way of forces provided by fluid power cylinders mounted on the frame and attached to the wiper blades. In the open position, the wiper blades are clear of the well string and in the closed position they are pressed against the well string. The wiper blades are vertically stacked in the closed position and overlap to assure full circumferential wiping of the well string. The frame is tethered to the container to prevent rotation due to well string friction. The cylinders are provided with fluid power by way of flexible hoses.
