G01V 5/10
US Classification:
2502697
Abstract:
A method for estimating a property of an earth formation, the method includes: conveying a carrier through a borehole penetrating the earth formation; irradiating the formation with neutrons from a neutron source disposed at the carrier; detecting a first signal from the formation due to the irradiating using a first radiation detector, the first signal being related to a saturation of a fluid in the formation; detecting a second signal from an element in the formation due to the irradiating using a second radiation detector, the second signal being related to an element emitting the second signal in the formation; and estimating the property from the first signal and the second signal.

US Classification:
2502691, 250256
Abstract:
The present disclosure relates to borehole logging methods and apparatuses for estimating formation properties using nuclear radiation, particularly an apparatus and method for estimating amounts of silicon and/or oxygen in the formation using exposure time information. The method may include using nuclear radiation information from at least one nuclear radiation detector to estimate at least one parameter of interest. The method may also include reducing an error in the estimated formation properties due to speed variations of a nuclear radiation source that activates the silicon and oxygen in the formation. The apparatus may include at least one nuclear radiation detector. The apparatuses may include an information processing device to perform the methods.

US Patent:
20120059587, Mar 8, 2012
Filed:
Mar 4, 2011
Appl. No.:
13/040332
Inventors:
Roger Marsh - Palmyra, AU
David M. Chace - Houston TX, US
Rafay Z. Ansari - Houston TX, US
Feyzi Inanc - Spring TX, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
G06F 19/00
G01V 5/04
US Classification:
702 8
Abstract:
A method of estimating fluid composition in an earth formation includes: generating at least one pulsed neutron measurement by a pulsed neutron tool; estimating a pulsed neutron fluid saturation by analyzing the at least one pulsed neutron measurement via a pulsed neutron model of the earth formation, the pulsed neutron model including expected pulsed neutron measurements relative to selected fluid composition and properties; comparing the pulsed neutron fluid saturation to a reference fluid saturation estimated via a downhole tool; adjusting the pulsed neutron model to at least substantially eliminate a difference between the pulsed neutron fluid saturation and the reference fluid saturation by adjusting at least one of the selected fluid composition and the selected fluid properties; and estimating at least one of the fluid composition and the fluid properties based on the adjusted model.
