    Sonic Survey's Pulsed Neutron Log

    The Pulsed Neutron log detects the water-hydrocarbon interface, i.e. the brine/diesel interface. It is also used to locate the interface below multiple strings of pipe. Another feature of the pulsed neutron is that no radiation is omitted unless the tool power is on. It is only enabled down hole. It is never enabled above ground.
