Abstract

Se describen sistemas y métodos para medir los rayos gamma naturales en un pozo que implican el uso de un detector de rayos gamma del fondo del pozo que proporciona señales que se incrustan con la energía depositada por los rayos gamma en el detector de rayos gamma del fondo del pozo y que almacenan señales digitales en los canales. Se toma un derivado de las señales digitales y se usa la ubicación del valor máximo del derivado para estabilizar al detector de rayos gamma ajustando el umbral o ganancia de acuerdo con el valor máximo del derivado o ajustando un amplificador o fuente de alto voltaje variable. Se presentan otros sistemas y métodos.
