Lithology determination from neutron activation of calcium and magnesium
Description
A method is described of investigating the lithology of an earth formation traversed by a well bore using neutron activation analysis gamma spectroscopy. The intensities of 27Mg and 49Ca gamma radiation are measured and the two intensities combined to provide an indication of the lithology of the earth formation and, in particular, of the extent of dolomitization of the formation.
