Basic Well Log Interpretation - Schlumberger
WebA common practice in log interpretation is to cross-plot various porosity log readings in order to determine formation lithology and compute porosity accurately. Crossplots of Sonic versus Density logs are widely used in the interpretation of shaly sands. For carbonates, Density versus Neutron cross-plots are commonly employed.
