US Patent:

20160320515, Nov 3, 2016

Filed:

Apr 29, 2015

Appl. No.:

14/699009

Inventors:

- Sugar Land TX, US
Jacques Orban - Katy TX, US
Jonathan D. Marshall - Springville UT, US
Scott R. Woolston - Provo UT, US
Daniel Hendricks - Provo UT, US
Neil Cannon - Woodland Hills UT, US

International Classification:

G01V 3/20

Abstract:

Devices and methods for well logging using a wear-resistant electrode are provided. A downhole device may include a drill collar and a first electrode mounted on the drill collar. Further, the first electrode may include a wear-resistant face. The first electrode may be movably coupled within the drill collar, and the first electrode may be configured to extend and retract into a wellbore to maintain contact with a wall of the wellbore. Furthermore, the first electrode may be configured to measure impedance of a geological formation.

Abstract:

Devices and methods for well logging using a wear resistant electrode are provided. A downhole device may include a drill bit, a gauge pad mounted on the drill bit, and a first electrode mounted in the gauge pad. An insulating polycrystalline diamond (PCD) material may surround at least a portion of the first electrode. Additionally, the first electrode may include an electrically conductive wear resistant contact point that maintains constant contact with a wall of a wellbore. Additionally, the first electrode may measure an impedance of a geological formation during a drilling operation.
