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 6, 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.

Pulsed-neutron logs, which include the thermal-decay-time and neutron lifetime logs, record the rate of decay of thermal neutrons. Chlorine, which is the most common element with high-capture cross-section(...), is found in most formations, and is the principal absorber of thermal neutrons. Consequently, this log determines mainly the amount of chlorine, i. e., the amount of saline water present.(...) 1, record 7, English, - pulsed%2Dneutron%20logging

(...). Après chaque impulsion, les neutrons sont rapidement décélérés jusqu'à vitesse thermique grâce à une série de collisions avec les noyaux des éléments dans les formations géologiques et le trou de forage.
