US Patent:

7227129, Jun 5, 2007

Filed:

Jun 22, 2005

Appl. No.:

11/158500

Inventors:

Stephen Riley - Spring TX, US
Benoit J. Guivarch - Portsall, FR
Darryl E. Trcka - Houston TX, US
David M. Chace - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01V 5/10

US Classification:

2502696, 2502697

Abstract:

A pulsed neutron source irradiates an earth formation. The irradiation produces Nfrom Oin a fluid in the borehole, and the gamma rays produced by the subsequent decay of Nare detected by a plurality of spaced apart detectors. The count rates of the detectors are accumulated over a time sampling interval to produce temporal signals. Processing of the temporal signals using correlation, differentiation and/or semblance techniques is used for determination of the flow velocity of one or more fluids in the borehole.

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01V 5/10

US Classification:

2502697

Abstract:

Appl. No.:

11/453115

Inventors:

Stephen Riley - Spring TX, US
Darryl E. Trcka - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01V 5/12
G01V 5/04

US Classification:

250265, 2502697

Abstract:

An apparatus for detecting gamma ray (GR) radiation having a plurality of detector cells arranged in an array is disclosed. Each cell includes a housing having an aperture, the housing comprising a GR absorbing material, and a GR detector disposed within the housing such that external gamma rays are received at the GR detector via the aperture. The apertures of each cell are aligned.

Appl. No.:

11/450497

Inventors:

Stephen Riley - Spring TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

G01V 5/10

US Classification:

2502696, 2502697, 250256, 250262, 250254

Abstract:

A method, apparatus, and machine-readable medium for evaluating an earth formation having a fluid mixture including oil and water therein. The earth formation is irradiated with a source and radiation resulting from interaction of the radiation with nuclei is measured at at least two detectors. A fluid zone parameter (FZP) indicative of oil saturation is determined and values of the FZP are established for at least two different values of oil saturation. A value of the oil saturation is estimated using the determined value of the FZP and established values of the FZP. The process may be repeated at a plurality of depths and the determined value of the FZP is displayed at the plurality of depths.
