Method And System Of Calculating Resistivity Of An Earth Formation
US Patent:
7746078, Jun 29, 2010
Filed:
Aug 29, 2008
Appl. No.:
12/201135
Inventors:
Michael S. Bittar - Houston TX, US
Guoyu (David) Hu - Houston TX, US
James Buchanan - The Woodlands TX, US

Assignee:
Halliburton Energy Services, Inc. - Houston TX
International Classification:
G01V 3/20
US Classification:
324366, 324375, 324357
Abstract:
Calculating resistivity of an earth formation. At least some of the illustrative embodiments are systems including: a first current source current return (CSCR) pair, said first CSCR pair comprises a first current source and a first current return, the first current return receives current from the first current source; a second CSCR pair, the second CSCR pair disposed along a longitudinal axis of said apparatus from the first CSCR pair, the second CSCR pair comprises a second current source and a second current return, and the second current return receives current from the second current source; and a monitor electrode disposed between the first CSCR pair and the second CSCR pair, a distance between the first current source and the monitor electrode is substantially equal to the distance between the second current source and the monitor electrode, and the monitor electrode monitors a first voltage and a second voltage.
Multi-Mode Oil Base Mud Imager
US Patent:
7098664, Aug 29, 2006
Filed:
Dec 22, 2003
Appl. No.:
10/743511
Inventors:
Michael S. Bittar - Houston TX, US

Assignee:
Halliburton Energy Services, Inc. - Houston TX
International Classification:
G01V 3/20
US Classification:
324367, 324375, 324357
Abstract:
A multi-mode oil base mud imager for use in non-conductive drilling fluid includes at least one current source—a current return pair, and one or more monitor electrodes not located between the current source and the current return of the current source-current return pair. Where more than one current source-current return pair is included, the tool is capable of multiple depths of investigation into surrounding formation. This data can be used as a gauge to establish the reliability of the data and to determine the resistance of the invaded zone around the borehole, as well as standoff distance of the tool from the borehole wall.
Method And System For Calculating Resistivity Of An Earth Formation
US Patent:
7427863, Sep 23, 2008
Filed:
Jul 13, 2006

International Classification:
G01V 3/20
US Classification:
324367, 324375, 324357
Abstract:
Method and system for calculating resistivity of an earth formation. At least some of the illustrative embodiments are methods comprising transmitting a current from a first current source, receiving at least part of the current at a first current return, said first current disposed remotely from the first current source, and measuring a first voltage at a monitor electrode, said monitor electrode disposed more remotely from below the first current source than said first current return.
