US Patent:

20170176627, Jun 22, 2017

Filed:

Dec 18, 2015

Appl. No.:

14/975649

Inventors:

- Sugar Land TX, US
Robert Callan - Rosenberg TX, US
Lukasz Zielinski - Cambridge, GB
Martin Hurlimann - Newton MA, US
Timothy Andrew John Hopper - Subiaco, AU

International Classification:

G01V 3/32
G01V 3/38

Abstract:

Systems and methods are provided for investigating a downhole formation using a nuclear magnetic resonance (NMR) tool having two or more radio frequency receiving coils. While the tool is moving through the borehole, the formation is magnetized and resulting signals are obtained. In accordance with the present approach, the acquired signals can be resolved azimuthally and can be reconstructed to obtain an indication of a parameter of the formation at multiple locations along the length of the borehole.

Abstract:

Systems and methods are provided for investigating a downhole formation using a nuclear magnetic resonance (NMR) tool. While the tool is moving through the borehole, the formation is magnetized and resulting signals are obtained. In accordance with the present approach, the acquired signals can be resolved azimuthally and/or laterally and can be reconstructed to obtain an indication of a parameter of the formation at multiple locations along the length of the borehole.
