Density Log Porosity - Shale Corrected - Schlumberger (1975)

Schlumberger (1975) also proposed a shale correction for porosity values derived from density logs. In this case, the equation includes density value of a nearby shale at the depth of the study area, and shale volume. The expression is the following:

Where:
• ɸDe= density log porosity - shale corrected
• ɸD= density log porosity
• ɸDshale= density log porosity in a nearby shale
• Vshale= shale volume
