Abstract
Method and apparatus for estimating a kerogen (organic) porosity of an earth formation. The method may include using at least one processor to estimate a kerogen porosity using NMR signals indicative to an inorganic porosity and NMR signals indicative of a total porosity for a volume of interest in an earth formation. The apparatus may include an NMR tool configured to acquire NMR signals indicative to an inorganic porosity and NMR signals indicative of a total porosity for a volume of interest in an earth formation.
