An analytical theory of epithermal neutron logging is presented. One‐group diffusion theory is applied to the slowing down of neutrons from a point fast neutron source in infinite continuous media, in a single cylinder, and in concentric cylinders representing a fluid‐filled borehole and the surrounding formation. Numerical results are given for the epithermal neutron flux in a water‐filled hole six inches in diameter, passing through limestone of 10 percent or 30 percent porosity. Preliminary semiquantitative agreement is obtained with the relative response of a commercial logging instrument in the range of 10 to 100 percent porosity.
