Abstract
A technique is provided for assaying the formations surrounding a borehole for uranium-bearing ore. A borehole logging tool employs a pulsed neutron source to cyclically irradiate the formations with neutrons. The tool measures neutron fluxes produced during the period of time that prompt neutrons are being produced by the neutron fission of uranium in the formations. The tool also measures the total neutron fluxes produced in response to each burst of the neutron source, such measurements being utilized to correct the neutron flux response of the borehole logging tool during the prompt fission neutron period for the effects of epithermal/thermal neutron moderation, scattering, and absorption within the borehole itself.
