Abstract

um aparelho para estimar uma propriedade de uma formação de solo e um fluido de furo de poço inclui um transportador configurado para ser disposto em um furo de poço, e um conjunto de medição de nêutrons pulsados que inclui uma fonte de nêutrons pulsada configurada para emitir nêutrons no furo de poço e na formação de solo, e um detector de raios gama. o aparelho também inclui um conjunto de medição de densidade de fluido incluindo o detector de raios gama e uma fonte de raios gama configurada para irradiar um fluido de furo de poço com raios gama. o detector de raio gama é posicionado em relação à fonte de raio gama, a fim de detectar tantos os raios gama resultantes de interações de nêutrons quanto raios gama emitidos do fluido de furo de poço em resposta à irradiação da fonte de raios gama. o aparelho inclui ainda um processador configurado para diferenciar um espectro de raios gama de nêutrons pulsados associado às interações de um espectro de raios gama de densidade.
