Record number: 2, Textual support number: 2 CONT
In the late 1950s the chlorine log was introduced to the petroleum industry. The amount of salt water in the formation was determined by use of the chlorine capture gamma emitted at 7.72 and 7.42 MeV. These early logs were sensitive to shale content and so were abandoned when pulsed-neutron sondes became available. 4, record 2, English, - chlorine%20log

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 3, 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 3, 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 4, English, - neutron%20log

gamma-gamma log : A "gamma-ray log" that records the intensity of induced gamma rays emitted by a subsurface formation as a result of gamma-ray bombardment. It is obtained by lowering into a borehole a source that emits gamma rays and a detector(shielded from the source) that receives signals indicative of the gamma rays scattered back to it from the surrounding rocks. 3, record 5, English, - gamma%2Dgamma%20logging
