Methodology of anisotropy reorientation from relaxation time for asphaltens in porous media

Most asphaltens consist of polyaromatic rings. These rings, stacked by association, lead to a crucial problem for oil wells, mainly in porous media. The purpose of this paper is to discuss the anisotropy reorientation from T1 and NOE 13C NMR data, using Huntressʹs equations. The method used here follows a previous study and completely corroborates it, and is easier to use.
