Abstract
- International audience; We present nuclear magnetic relaxation dispersion of longitudinal relaxation rates 1/T 1 (NMRD) and 2D spin-correlation T 1-T 2 at different frequencies for oil and brine confined in shale oil rocks. We describe the nuclear spin relaxation models used for obtaining important dynamical and structural parameters from these experiments. These models allow interpreting the very different T 1 /T 2 ratio observed for these petroleum fluids on the 2D spin-correlation T 1-T 2 observed at two frequencies. They give also new informations on the dynamics and wettability of the embedded fluids as well as some structural measurement on the kerogen pore size.
