Electromagnetic Linear Drive Source For Logging-While-Drilling/Wireline Acoustic Applications

US Patent:
2010014, Jun 10, 2010
Filed:
Dec 8, 2008
Appl. No.:
12/330340
Inventors:
Vladimir Dubinsky - Houston TX, US
Douglas J. Patterson - Spring TX, US
Jonathan F. Hook - Houston TX, US
David H. Lilly - Houston TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
G01V 1/40
US Classification:
367 25
Abstract:
An apparatus and method for providing a downhole acoustic source is disclosed. The acoustic source includes a piston configured to oscillate in an axial direction of the acoustic source and produce an acoustic signal in a medium in contact with an exterior surface of the piston, and an elastomer disposed on an interior side of the piston, an acoustic impedance of the elastomer selected to match an acoustic impedance of the piston. A permanent magnet is configured to provide a permanent magnetic field oriented in the axial direction, and a coil disposed on an interior side of the piston produces an alternating magnetic field in the region of the permanent magnetic field. The elastomer may be, for example, a silicon rubber, a silicone jelly, and a silicone oil. A plurality of acoustic sources may be arranged to produce an acoustic dipole configuration or an acoustic quadrupole configuration.

Sleeve For Logging While Drilling Electromagnetic Sensor

US Patent:
2013027, Oct 24, 2013
Filed:
Apr 18, 2012
Appl. No.:
13/449940
Inventors:
Jonathan F. Hook - Houston TX, US
John F. Groweg - Houston TX, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
E21B 49/00
US Classification:
175 50
Abstract:
An apparatus for measuring a characteristic of an earth formation includes a drill collar configured to be inserted into a borehole of the earth formation, an electromagnetic sensor on the drill collar, and a non-conductive sleeve surrounding a circumference of the drill collar including the electromagnetic sensor and configured to press directly against the electromagnetic sensor.

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
G01V 5/06
US Classification:
250254, 250253, 2502694
Abstract:
An apparatus for measuring radiation in a borehole penetrating the Earth, the apparatus includes: a downhole tool having a structure defining a cavity; and one or more radiation detection components integrated into the cavity and configured to measure the radiation. An apparatus conveyable through a borehole for measuring radiation downhole and a method of producing a downhole apparatus for measuring radiation are provided.
