Abstract

L'invention porte sur une méthode et le système associé de séparation de phases liquides lors de mesures par RMN dans des puits (107). L'invention s'applique particulièrement à la séparation de la saumure d'avec les hydrocarbures en recourant à une diffusion renforcée pour fixer une limite supérieure à la distribution spectrale T2 de la saumure. Les paramètres modifiables en vue du renforcement de la relaxation par diffusion lors de la mesure comprennent l'espacement entre échos TE, et le gradient de champ magnétique G (110) de l'outil de mesure.
