Abstract
MEDIÇÕES DE DENSIDADE SEM FONTE COM NORMALIZAÇÃO DE GAMA INDUZIDA POR NÊUTRON. Trata-se de métodos, sistemas, dispositivos e produtos para estimar pelo menos um parâmetro de interesse de um volume de uma formação de terra, incluindo densidade, porosidade e saturação de fluido do volume. Os métodos podem incluir normalizar informações de radiação relacionadas a emissões de radiação a partir de uma fonte nuclear distribuída de modo espacial e indicativas de uma propriedade do volume de terra com o uso de um fator de correção determinado com o uso de uma litologia estimada do volume. A fonte nuclear pode estar no volume. As emissões de radiação podem ser geradas por irradiação de nêutrons de pelo menos um nuclídeo no volume. O fator de correção pode ser determinado com o uso de qualquer um dentre a densidade nuclear do pelo menos um nuclídeo; uma concentração estimada do pelo menos um nuclídeo no volume; ou um parâmetro relacionado à concentração do nuclídeo no volume. As emissões podem incluir raios gama.
