Abstract

"MéTODO E SISTEMA PARA ESTABILIZAçãO DE UM GANHO DE UM DETETOR DE RAIOS GAMA PARA UTILIZAçãO EM UMA FERRAMENTA DE PERFILAGEM DE INTERIOR DE POçO, E MéTODO E SISTEMA PARA AVALIAçãO DE UMA ATIVIDADE DE RAIOS GAMA NATURAIS NO INTERIOR DE UM FURO PERFURADO". Trata-se de um método para estabilização de um ganho de um detetor de raios gama para utilização em uma ferramenta de perfilagem de interior de poço. O método é baseado em um processamento de um pico de dispersão refletida ('backscatter') de um espectro gama completo.
