H04B 10/08
US Classification:
398 25
Abstract:
A method for estimating a parameter includes: generating an optical signal, the optical signal modulated via a modulation signal having a variable modulation frequency over a period of time; transmitting the modulated optical signal from a light source into an optical fiber, the optical fiber including at least one sensing location configured to reflect light; receiving a reflected signal including light reflected from the at least one sensing location; and demodulating the reflected signal with a reference signal, the reference signal including a time delay relative to the modulation signal based on a distance between the light source and the at least one sensing location.

US Patent:
20120179378, Jul 12, 2012
Filed:
Jan 6, 2011
Appl. No.:
12/985773
Inventors:
Roger G. Duncan - Christiansburg VA, US
Brooks A. Childers - Christiansburg VA, US
Robert M. Harman - Troutville VA, US
Ajit Balagopal - Christiansburg VA, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
G01V 5/04
G06F 19/00
US Classification:
702 8
Abstract:
A apparatus for monitoring a downhole component is disclosed. The apparatus includes: an optical fiber sensor including a plurality of sensing locations distributed along a length of the optical fiber sensor; an interrogation assembly configured to transmit an electromagnetic interrogation signal into the optical fiber sensor and receive reflected signals from each of the plurality of sensing locations; and a processing unit configured to receive the reflected signals, select a measurement location along the optical fiber sensor, select a first reflected signal associated with a first sensing location in the optical fiber sensor, the first sensing location corresponding with the measurement location, select a second reflected signal associated with a second sensing location in the optical fiber sensor, estimate a phase difference between the first signal and the second signal, and estimate a parameter of the downhole component at the measurement location based on the phase difference.

Strain Locked Fiber Optic Cable And Methods Of Manufacture

View page
US Patent:
20180245460, Aug 30, 2018
Filed:
Apr 24, 2018
Appl. No.:
15/961410
Inventors:
Ajit Balagopal - Christiansburg VA, US
Juan P. Franco - Blacksburg VA, US
Paul F. Wysocki - Blacksburg VA, US
Assignee:
Baker Hughes, a GE company, LLC - Houston TX
International Classification:
E21B 47/12
G02B 6/44
Abstract:
An embodiment of a method of manufacturing a fiber optic cable includes selecting a cable support structure configured to support an optical fiber sensor, adhering the optical fiber sensor to the cable support structure by applying a temporary adhesive, and installing a protective layer around the cable support structure and the temporarily adhered optical fiber sensor. The method further includes removing a bond between the optical fiber sensor and the temporary adhesive, wherein removing the bond includes injecting a debonding material into a space formed between the cable support structure and the protective layer, and injecting a permanent adhesive into the space, the permanent adhesive configured to immobilize the optical fiber sensor relative to the protective layer and allow strain to be transferred from the protective layer to the optical fiber sensor.

Downhole Optical Fiber With Array Of Fiber Bragg Gratings And Carbon-Coating

US Patent:
20180230049, Aug 16, 2018
Filed:
Feb 13, 2017
Appl. No.:
15/431032
Inventors:
Paul Francis Wysocki - Blacksburg VA, US
Ajit Balagopal - Blacksburg VA, US
Christopher Howard Lambert - Blacksburg VA, US

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
C03C 25/62
C03B 37/03
C03C 25/10
G02B 6/02
Abstract:
A method for producing a protected optical fiber with distributed sensors includes heating an optical fiber preform and drawing the heated optical fiber preform to form a drawn optical fiber. The method also includes coating the drawn optical fiber with a carbon coating after the optical fiber is drawn to provide a carbon coated optical fiber and then writing a series of fiber Bragg gratings (FBGs) into the carbon coated optical fiber to provide a carbon coated optical fiber with FBGs. The method further includes coating the carbon coated optical fiber with FBGs with one or more layers of a polymer to provide the protected optical fiber with distributed sensors, wherein the heating, drawing, carbon coating the drawn optical fiber, writing, coating the carbon coated optical fiber are performed in that sequence while the protected optical fiber is being produced.
