BEHIND CASING WATER FLOW DETECTION USING CONTINUOUS OXYGEN ACTIVATION (D#74,199-F) ABSTRACT OF THE DISCLOSURE Measurement of the volume flow rate and linear flow velocity of undesired behind casing water flow is provided. A well tool having a 14 MEV neutron source is used to con- tinuously irradiate earth formations behind well casing. The continuous neutron irradiation activates elemental oxygen nuclei comprising the molecular structure of any undesired water flow to be detected. Dual spaced gamma ray detectors located above or below the neutron source detect the decay of unstable isotope nitrogen 16 and from these indications the linear flow velocity of the undesired water flow is deduced. By then estimating the distance R to the undesired flow region the volume flow rate V may be deduced. I
