Quantitative NMR spin-lattice-relaxation imaging of brine in sandstone reservoir cores

Two- and three-dimensional quantitative, saturation-recovery, NMR imaging has been applied to two sandstone reservoir cores. M 0 and T 1 images of high quality have been obtained with reasonable data-acquisition and data-processing times. The T 1 and T 2 processes have been shown to be correlated; t...

Description
Summary:Two- and three-dimensional quantitative, saturation-recovery, NMR imaging has been applied to two sandstone reservoir cores. M 0 and T 1 images of high quality have been obtained with reasonable data-acquisition and data-processing times. The T 1 and T 2 processes have been shown to be correlated; the variations of the parameters within the images and the differences between the bulk and image relaxation values are discussed. The results of a quantitative T 1 imaging experiment of a phantom are also presented in order to demonstrate the advantages of quantitative NMR imaging over standard bulk measurements.
