  • Epithermal neutron porosity measurement
    Patent number: 4638161
    Abstract: Earth formations penetrated by a borehole are irradiated with pulses of fast neutrons. The epithermal neutrons resulting from moderation of the fast neutrons are detected in a plurality of time intervals to determine the porosity of the adjacent earth formations independently of lithology. Statistical results are improved by taking the ratio of the count rate during build-up of the epithermal neutron population to the count rate during die-away.

  • Method for simultaneous measurement of thermal neutron decay components
    Patent number: 4409481
    Abstract: A method is disclosed for simultaneous determination of borehole and formation thermal neutron decay time components. The methods employ pulsed high energy neutron sources and time gated dual spaced detectors. Exponential decay curves are assumed for each of the components and iterative least squares fitting employing rapid convergence techniques are utilized.
