Probing multi-dynamics of crude oils by high field 2D NMR DOSY and relaxometry

- Comprehensive multiscale NMR method for probing the crude oil dynamics in bulk and confinement.
- 2D NMR DOSY experiments evidence two hydrocarbon species in crude oil in presence of asphaltene.
- First observation of dynamics of hydrocarbons at proximity of asphaltene by nuclear magnetic relaxation.
- Original surface relaxation model in crude oils with and without asphaltene.
- Role of asphaltene nanoaggregates and macroaggregtaes in the dynamics of crude oils confined in rocks.
