1. A method comprising:
lowering a pulsed-neutron logging tool downhole comprising a near detector and a far detector;
measuring a carbon to oxygen ratio from the near detector;
measuring a carbon to oxygen ratio from the far detector;
measuring a ratio of inelastic count rates, wherein the ratio of inelastic count rates is a ratio of near detector inelastic count rates to far detector inelastic count rates; and
plotting the measured ratios in a prismatic grid.
