Abstract

El aparato para determinar la densidad de formaciones subterráneas que rodean un sondeo, tal como una herramienta de registro de línea de alambre o una herramienta de registro mientras que se perfora, incluye una fuente de neutrones de alta energía para irradiar las formaciones desde dentro del sondeo, y un detector que detecta los rayos gamma en el sondeo resultantes de la irradiacion de las formaciones con neutrones de alta energía. Los rayos gamma detectados se analizan para determinar la densidad de las formaciones.
