Method For Testing Connectors

US Patent:
8408295, Apr 2, 2013
Filed:
Feb 4, 2010
Appl. No.:
12/700374
Inventors:
David Levy - Broussard LA, US
Assignee:
Petro Technologies, Inc. - Broussard LA
International Classification:
E21B 47/06
US Classification:
16625001, 16625008, 166379, 1662426, 285 96, 285113
Abstract:
A testing method for connectors usable with oil or natural gas wells using a test part connector and a control component connector. The method uses a test fluid in a test reservoir that is pumped to each connector simultaneously, uses a test part pressure transducer and a control component pressure transducer to create a test response and a control response. The responses are then transmitted as compared results to a user.

Externally Testable Redundant Connections For Subsea Wells

US Patent:
7219736, May 22, 2007
Filed:
Nov 22, 2004
Appl. No.:
10/994779
Inventors:
David Levy - Broussard LA, US
Assignee:
Petrotechnologies, Inc. - Lafayette LA
International Classification:
E21B 29/12, E21B 43/017
US Classification:
166336, 166337, 16625001, 166 861
Abstract:
An externally testable redundant connection for a subsea well includes a tube, a connector assembly, and collar. The connector assembly includes a jam nut over the tube; a ferrule over the tube adjacent the jam nut; and a double jam nut disposed over the tube adjacent to the ferrule. The double jam nut includes a test port adapted to receive a test fluid through the test port for determining if the primary seal and the secondary seal are providing a leak proof sealing engagement. The collar engage the tube and transfers an axial force from the double jam nut and compresses the tube into a female profile forming a primary seal. A secondary seal is formed from a compression of the ferrule into the double jam nut using the jam nut.

System And Method For Controlling Speed Of A Moving Vehicle

US Patent:
7711468, May 4, 2010
Filed:
Jan 7, 2008
Appl. No.:
11/970069
Inventors:
David Levy - Broussard LA, US
International Classification:
G06F 19/00
US Classification:
701 70, 701 33, 701 93, 701207, 701213, 34235706, 34235708, 340441
Abstract:
A system, a method and device for controlling speed of a moving vehicle, using portable and repositionable global positioning devices, speed limit processors, and a database of legal vehicle speed limits is in communication with the speed limit processor. Computer instructions instruct the speed limit processor to match the current location of the moving vehicle with a legal vehicle speed limit for a defined location using the database. The speed limit processor communicates the legal vehicle speed limit to the vehicle processor to control the speed of the moving vehicle.

System And Method For Testing Fluid Seals For Leaks

US Patent:
2013007, Mar 21, 2013
Filed:
Dec 8, 2011
Appl. No.:
13/315118
Inventors:
David Levy - Broussard LA, US
Assignee:
PETROTECHNOLOGIES, INC. - Broussard LA
International Classification:
G06F 19/00, E21B 19/00, G01M 3/28, E21B 33/06
US Classification:
702 51, 166 854, 1662426, 73 405 R
Abstract:
A system and method for testing a fluid seal in a device can include pumping fluid to the device and a control device simultaneously, while measuring the pressure of the fluid pumping to both devices. A change in volume of the fluid in the control device can be initiated, a change in pressure difference associated with the change in volume can be determined, and a leak test ratio can be formed therefrom. Changes in the pressure difference can be used to determine the presence of fluid leaks, which can be presented as test results to users connected to a network. A leak volume can be determined using the change in pressure difference and the leak test ratio.

High Pressure Energizable Tube Connector For A Well

US Patent:
7784838, Aug 31, 2010
Filed:
Jun 21, 2007
Appl. No.:
11/766541
Inventors:
David Levy - Broussard LA, US
Assignee:
Petro Technologies, Inc. - Broussard LA
International Classification:
F16L 19/06
US Classification:
285342, 285242, 285245, 285256, 285353
Abstract:
A high pressure energizable tube connector for a well comprising a tube; a first connector assembly comprising: a female profile disposed over the tube and a first ferrule disposed over the tube adjacent the female profile; a second connector assembly comprising: an inverted jam nut disposed over the tube and a second ferrule disposed over the tube adjacent the inverted jam nut, wherein the second ferrule extends along the tube in a direction opposite the first ferrule; a nipple comprising a test port, wherein the nipple is disposed over the tube between the first ferrule and the second ferrule; a primary seal formed by compressing the first ferrule into the female profile using a pressure from the test port; and a secondary seal formed by compressing the second ferrule into the inverted jam nut using the pressure from the test port.

Externally Testable Redundant Seal Connector

US Patent:
8037933, Oct 18, 2011
Filed:
Oct 9, 2008
Appl. No.:
12/248558
Inventors:
David Levy - Broussard LA, US

Abstract:
An externally testable redundant seal connector for a well comprising a connector body and a ferrule disposed on an end of the connector body. The ferrule is adapted for forming a primary seal between an outer diameter of the connector body and a profile in a mandrel. A sealing groove can be formed on the outer diameter of the connector body. A sealing device can be disposed in the sealing groove. A conduit can be formed in the connector body parallel to but disconnected from the thru-bore. Ports can be disposed in the connector body for receiving fluid and introducing fluid to at least one conduit. A plug can be insertable in each port upon completion of testing wherein each plug forms a secondary seal between the connector and the mandrel.

Method To Determine Connector Leaks During Testing

US Patent:
8078412, Dec 13, 2011
Filed:
Apr 29, 2009
Appl. No.:
12/432673
Inventors:
David Levy - Broussard LA, US
Assignee:
PetroTechnologies, Inc. - Broussard LA
International Classification:
G06F 17/00
US Classification:
702 51
Abstract:
A method for evaluating the leak tightness of a connector, or multiple connectors. The method uses an administrative server having a library of pressure and temperature information on various connectors, as well as the ability to report pressure and temperature data to a network as uncorrected and corrected responses. The method uses a data logger for recording pressure and temperature readings and also reporting corrected and uncorrected responses using one or more equations to shorten the test time by at least 50 percent or to about 5 minutes or less. The method uses a test pump for applying pressure to a connector to generate a corrected pressure which indicates leaks when the corrected pressure changes.
