Asphaltenes cause many problems in crude oil transportation, refinery, and production. A clear understanding of asphaltene behavior in crude oils is thus crucial for improving crude oil production. Here, we used noninvasive multiscale NMR techniques such as low field NMR 2D D–T 2, T 1–T 2, nuclear m...
