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 5, English, - chlorine%20log
