Abstract
Un aspecto de una formación se puede estimar colocando una herramienta de espectroscopía que incluye una fuente de neutrones y un detector de rayos gamma en un hoyo y realizando una pluralidad de mediciones ambientales. Los neutrones se emiten desde la herramienta de espectroscopía nuclear de manera que algunos de los neutrones generan rayos gamma desde una formación adyacente a la herramienta de espectroscopía nuclear, algunos de los neutrones generan rayos gamma desde los elementos dentro de la herramienta de espectroscopía nuclear y algunos de los neutrones generan rayos gamma desde un elemento en el lodo de perforación. Se puede detectar un espectro de energía de los rayos gamma inducidos por los neutrones emitidos con la herramienta. El espectro de energía de rayos gamma detectado se puede analizar usando una combinación de los espectros estándares, donde la forma de al menos uno de los espectros estándares se varía basado en las mediciones ambientales para representar los efectos del ambiente sobre los espectros de rayos gamma.
