Abstract

FERRAMENTA DENTRO DE POÇO CAPAZ DE SER BAIXADA PARA UM POÇO DE UMA FORMAÇÃO SUBTERRÂNEA. Sistema, métodos e dispositivos para determinar uma porosidade de uma formação subterrânea corrigida para efeitos de poço são fornecidos. Tal dispositivo pode ser uma ferramenta dentro de poço capaz de ser baixada em um poço de uma formação subterrânea que pode incluir uma fonte de nêutrons, dois ou mais detectores de nêutrons e circuitos de processamento de dados. A fonte de nêutrons e pode emitir nêutrons para a formação subterrânea. Os dois ou mais detectores de nêutrons respectivamente podem ser dispostos em duas ou mais orientações azimutais dentro da ferramenta dentro de poço e podem detectar nêutrons espalhados pela formação subterrânea ou pelo fluido de poço, ou ambos. Baseado nos nêutrons detectados pelos detectores de nêutrons, os circuitos de processamento de dados. podem determinar uma porosidade de formação de poço.
