A specialized radioactivity log of neutron-gamma log type. A neutron generator produces short bursts of high-energy neutrons (about 14 MeV), which are slowed in the borehole and nearby rocks to thermal energy level (about 0.025 eV); capture by nuclei (especially chlorine) results in gamma-ray emissions. The log is used in cased oil wells to determine changes in fluid saturation during oil production. 2, record 4, English, - pulsed%20neutron%20log

[La] diagraphie de neutrons pulsés [...] est appelée «Neutron Lifetime Log» (NLL) par Dresser-Atlas et «Thermal Decaytime Log» (TDT) par Schlumberger. Des neutrons très rapides (14 MeV) sont émis par impulsions de 20 à 30 microsecondes avec une récurrence de 1 000 impulsions par seconde. Les sondes sont de type cylindrique et leur position dans le sondage est indifférente. 1, record 4, French, - diagraphie%20de%20relaxation%20neutronique

A radioactivity log curve that indicates the intensity of radiation (neutrons or gamma rays) produced when the rocks in a borehole are bombarded by neutrons from a sonde. It indicates the presence of fluids (but does not distinguish between oil and water) in the rocks, and is used with the gamma-ray log to differentiate porous from nonporous formations. 3, record 5, English, - neutron%20log
