Electromagnetic Induction Well Logging Instrument Having Azimuthally Sensitive Response

View page
US Patent:
6509738, Jan 21, 2003
Filed:
Jul 14, 2000
Appl. No.:
09/617528
Inventors:
Gerald N. Minerbo - Missouri City TX
Brian Clark - Sugar Land TX
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01V 328
US Classification:
324339
Abstract:
An induction logging instrument is disclosed which includes at least one induction transmitter arranged as an axial magnetic dipole and at least one differential axial magnetic dipole receiver disposed at a selected axial distance from the at least one induction transmitter. In one embodiment, the receiver includes a pair of coils, each wound on an axis substantially parallel to an axis of the instrument. Each of the coil axes is displaced from the instrument axis by a substantially equal lateral distance in opposite directions. Each of the pair of coils is disposed at substantially the same axial position along the instrument, and the coils are interconnected in inverse series. In another embodiment, the receiver includes two pairs of coils, each wound on an axis substantially parallel to the axis of the instrument. Each of the coil axes in each pair is displaced from the instrument axis by a substantially equal lateral distance an in opposed directions. The pairs are substantially orthogonal to each other.

Method And System For Determining Formation Anisotropic Resistivity With Reduced Borehole Effects From Tilted Or Transverse Magnetic Dipoles

View page
US Patent:
6556015, Apr 29, 2003
Filed:
Oct 11, 2001
Appl. No.:
09/975411
Inventors:
Dzevat Omeragic - Sugar Land TX
Gerald N. Minerbo - Missouri City TX
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01V 326
US Classification:
324338, 324343
Abstract:
Systems and methods are provided for determining subsurface formation properties using an antenna system disposed within a borehole traversing the formation. A logging system includes a well tool implemented with an antenna system having transverse or tilted magnetic dipoles. One antenna implementation uses a set of three coils having non-parallel axes. Through mechanical or electromagnetic rotation of an antenna about its axis in order to maximize or minimize couplings, the systems and methods are used to estimate formation anisotropic resistivity, providing reduced borehole effects in vertical and small deviation wells. This invention may also be applied in deviated wells when the borehole is perpendicular to the strike direction, as is often the case in wireline logging.

Directional Electromagnetic Measurements Insensitive To Dip And Anisotropy

View page
US Patent:
6969994, Nov 29, 2005
Filed:
Mar 29, 2002
Appl. No.:
10/113132
Inventors:
Gerald N. Minerbo - Missouri City TX, US
Dzevat Omeragic - Sugar Land TX, US
Richard A. Rosthal - Houston TX, US
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01V003/10
G01V003/08
US Classification:
324343, 324338, 324339
Abstract:
Systems and methods are provided for directional propagation-type logging measurements not sensitive to dip and anisotropy over a wide frequency range. Estimates of the distance of the logging tool to a bed boundary are obtained using “up-down” measurements with antenna configurations having tilted magnetic dipoles. These estimates are insensitive to anistropy and dip, undesirable complications of directional measurements.

Semi-Conductive Shell For Sources And Sensors

View page
US Patent:
7026813, Apr 11, 2006
Filed:
Sep 25, 2003
Appl. No.:
10/605375
Inventors:
Dean M. Homan - Sugar Land TX, US
Gerald N. Minerbo - Missouri City TX, US
Sofia Davydycheva - Missouri City TX, US
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01V 3/00
G01V 3/02
G01V 3/18
US Classification:
324247
Abstract:
A composite shell adapted to cover a source or sensor, particularly for subsurface applications. The shell provides transparency to the passage of signals to or from the source or sensor. The shell is adapted with a uniform semi-conductive surface providing a path for electric currents flowing within a subsurface borehole to short near the source or sensor.

7091877, Aug 15, 2006
Filed:
Jan 14, 2004
Appl. No.:
10/707813
Inventors:
Thomas D. Barber - Houston TX, US
Stephen D. Bonner - Sugar Land TX, US
Dean M. Homan - Sugar Land TX, US
Gerald N. Minerbo - Missouri City TX, US
Richard A. Rosthal - Houston TX, US

US Patent:
7414391, Aug 19, 2008
Filed:
Jul 10, 2003
Appl. No.:
10/616710
Inventors:
Dean M. Homan - Sugar Land TX, US
Richard A. Rosthal - Houston TX, US
Gerald N. Minerbo - Missouri City TX, US
Thomas D. Barber - Houston TX, US
Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01R 35/00
G01R 33/00
G01V 3/10
G01V 1/40
US Classification:
324202, 324225, 324339, 702 7
Abstract:
Techniques for calibrating an electromagnetic logging tool equipped with a plurality of antennas, with at least one antenna having its axis at an angle with respect to a tool axis, include disposing a test loop about the tool such that an axis of the tool and a plane on which the test loop lies form a tilt angle that is between about 0 and 90 degrees. An induced signal is measured at one of the antennas by energizing another of the antennas. Embodiments analyze the induced signal corresponding to a max or min extrema associated with a coupling effect due to the test loop. In other embodiments a corrected signal is compared with a calculated signal.
