Abstract
Borehole logging methods and apparatuses for estimating formation properties using nuclear radiation, particularly an apparatus and method for estimating amounts of silicon and/or oxygen in the formation. Methods include estimating a formation property using an oxygen estimate and at least a formation lithology. The method may include using nuclear radiation information from at least one nuclear radiation detector generate the oxygen estimate. The apparatus may include at least one nuclear radiation detector. The apparatuses may include an information processing device to perform the methods.
