Abstract

método para determinação de saturação trifásica de tubo de sondagem atravessante. um método de avaliar um parâmetro de interesse de uma formaão de terra apresentando um fluido contido em poros da formação de terra, o método incluindo a condução de um condutor através de um furo de sondagem que penetra a formação de terra, a irradiação da formação de terra com nêutrons de uma fonte de nêutrons disposta no condutor , a medição da radiação emitida da formação de terra resultante da irradiação usando pelo menos um detector, o cálculo ou a determinação de um parâmetro matemático da radiação medida por pelo menos um detector, a previsão de valores do parâmetro matemático sobre uma faixa de valores de uma propriedade de formação de terra, e a comparação do parâmetro matemático aos valores previstos para avaliar o parâmetro de interesse.
