Kind Code:
A3
Abstract:
A method for estimating a concentration of carbon dioxide (CO2) in a formation penetrated by a borehole, the method includes: conveying a carrier through the borehole; irradiating the formation with neutrons from a neutron source disposed at the carrier; detecting photons from the formation resulting from the irradiating; and estimating the concentration of CO2 from data acquired from the detecting.
