A multifrequency method and apparatus for NMR logging. The apparatus and method uses a triple-wait-time (TWS1, TWS2, TWL1) NMR sequence to determine gas and light-oil filled porosity over a broad range of reservoir conditions. A set of conditions is derived for the selection of optimum acquisition parameters. The conditions are developed to aid in the selection of wait time combinations. Image
L'invention concerne un appareil et des procédés multifréquence de diagraphie par IRM utilisant une séquence IRM à temps d'attente triple (TWS1, TWS2, TWL1) pour déterminer une porosité pleine de gaz ou d'huile légère, sur une large gamme de conditions de réservoir. Un ensemble de conditions est dérivé pour la sélection de paramètres d'acquisition optimaux. Les conditions sont mises au point pour contribuer à la sélection de combinaisons de temps d'attente.
