SCINTILLATION MATERIALS OPTIMIZATION IN SPECTROMETRIC DETECTORS FOR DOWNHOLE NUCLEAR LOGGING WITH PULSED NEUTRON GENERATOR BASED TOOLS

摘要

Methods, systems, and devices for evaluating an earth formation intersected by a borehole. Methods may include irradiating the earth formation using a radiation source to provoke radiation from the formation responsive to the irradiation; taking a radiation measurement and thereby generating radiation measurement information by producing light scintillations from a scintillation material responsive to the absorption by the scintillation material of the radiation from the formation and substantial intrinsic radiation of the scintillation material; and estimating a parameter of interest of the earth formation using the radiation measurement information.
