1. Reflection coefficients are calculated from P-sonic, S-sonic and density logs using the Zoeppritz equations.
2. The combination of neutron and density logs takes advantage of the fact that lithology has opposite effects on these two porosity measurements.
3. This requires accurate p-sonic, s-sonic and density logs tied to the appropriate events on the seismic data.
4. This characteristic allows a neutron porosity log to be used with other porosity logs ( such as a density log ) to detect gas zones and identify gas-liquid contacts.
5. Greensands may cause varying degrees of difficulty for porosity log analysis . radicals affect neutron logs; the iron component is troublesome, and varying clay hydration needs to be considered for density log interpretation.
