US Classification:

702 11, 324347
Abstract:

A method for correcting a measurement of a property of a subsurface material includes: selecting an instrument that includes a test circuit and a separate sensor, the sensor adapted for transmitting an electric signal into the subsurface material and receiving a data signal from the subsurface material, wherein the test circuit and the sensor are switchably coupled to an electronics unit of the instrument; receiving the electric signal from the test circuit in the electronics unit; using the electronics unit, measuring at least one output characteristic of the instrument; and applying a correction to the data signal according to the measured output characteristic. An instrument and an additional method are provided.

Filed:

Jul 31, 2008
Appl. No.:

12/183809
Inventors:

Carlos A. Yanzig - Houston TX, US
Assignee:

BAKER HUGHES INCORPORATED - Houston TX
International Classification:

G01V 3/20
US Classification:

324355
Abstract:

A method and apparatus for imaging wellbores is provided that in one aspect may include inducing an electrical signal into a formation, receiving a current signal responsive to the induced electrical signal by at least one measure electrode placed in a pad disposed in the wellbore, generating an impedance signal in response to the received current signal using a receiver circuit placed in the pad and coupled to the at least one measure electrode and providing an image of the wellbore wall using the impedance signal.

US Patent:

58412816, Nov 24, 1998
Filed:

Mar 22, 1996
Appl. No.:

8/620613
Inventors:

David R. Beard - Houston TX
Carlos A. Yanzig - Houston TX
Leonty A. Tabarovsky - Houston TX
Assignee:

Western Atlas International, Inc. - Houston TX
International Classification:

G01V 328
G01V 310
G01V 315
US Classification:

324339
Abstract:

A method of determining the conductivity of earth formations penetrated by a wellbore. The method includes inserting an induction well logging instrument into the wellbore. The instrument includes a transmitter, a source of alternating current connected to the transmitter, and a receiver. The transmitter is energized with the alternating current, voltages induced in the receiver are recorded, and area enclosed with respect to a baseline, by voltage peaks present in the recorded voltages is determined. The enclosed area corresponds to the conductivity.
