It is well documented in the literature that asphaltene deposition within the formation (pore plugging) can alter the wettability of the system. This wettability effect may be observed on a 2D NMR (D vs. T2,int.) plot from the NMR logging tool. In turn, we can interpret this alteration in the wettability as being caused by asphaltene deposits in the formation.
