Neutron Log Porosity - Shale Corrected -Dewan (1983)
Dewan (1983) also proposed an equation for shale correction of the porosity values derived from neutron well logs, and in the equation, it is included the shale volume value and the neutron porosity value of a nearby shale at the depth of interest. The equation is the following:
- Where:
- ɸNe= neutron log porosity - shale corrected
- ɸN= neutron log porosity
- ɸNsh= neutron log porosity in a nearby shale
- Vshale= shale volume
