This document outlines the "Six Ko Ko Rules" for quickly interpreting well logs in 5 minutes or less. The rules involve plotting gamma ray, resistivity, and density-neutron logs in a specific sequence and order. Key patterns in the direction the curves deflect can then indicate different rock and fluid types, including tight reservoirs, shale, water-bearing reservoirs, oil-bearing reservoirs, and gas reservoirs. While not foolproof, following the Six Ko Ko Rules provides a good starting point for interpreting well logs.
