Abstract: A method for determining a density may comprise disposing a nuclear density tool into a wellbore. The nuclear density tool may comprise a gamma source and a first gamma detector, wherein the first gamma detector and the gamma source are disposed on a longitudinal axis of the nuclear density tool. The method may further comprise transmitting an energy from the gamma source, detecting the energy reflected with the first gamma detector, recording a count rate of the energy at the first gamma detector, and identifying a density of a first layer from the count rate, a mass attenuation coefficient, and a source-to-detector distance. A system for determining a density may comprise a nuclear density tool. The nuclear density tool may comprise a gamma source configured to transmit an energy and a first gamma detector configured to detect reflected energy. The system may further comprise an information handling system.

Abstract: A nuclear density tool may comprise a gamma source, a gamma detector, wherein the gamma detector and the gamma source are disposed on a longitudinal axis of the nuclear density tool, and a housing, wherein the gamma source and the gamma detector are disposed in the housing. The nuclear density tool may further comprise a first cutout in the housing positioned to allow the gamma source to emit an energy through the housing and a second cutout in the housing posited to allow the gamma detector to detect the energy through the housing.

Abstract: A method and system for determining a density. The method may comprise disposing a nuclear density tool into a wellbore, performing a spectral deconvolution, determining an energy channel for a first measurement layer, recording a count rate with the gamma detector for the first measurement layer, applying a slope operator to the count rate, and identifying a first density of the first measurement layer. The system may comprise a nuclear density tool that includes a gamma source and a gamma detector configured to record a count rate, wherein the gamma detector and the gamma source are disposed on a longitudinal axis of the nuclear density tool. The system may also comprise an information handling system.
