Popis:	The improvement of the oil production forecast and the recovery strategy is closely related to a better understanding of the oil reservoir wettability. As there is a need of a description of the spatial distribution of wettability down to the pore scale, new tools allow to enhance very fine scale wettability contrasts and to evidence the importance of mineralogy. Among them, we propose to use the nuclear microprobe analysis (NMA) for the qualitative and quantitative study of the organic matter/mineral interactions i.e. the description of the reservoir rock wettability. NMA, field emission SEM and AFM techniques are used to image and study the mechanisms and kinetics of the sorption of the organic matter on model samples: the organic film thicknesses and the major elemental contents (carbon and nitrogen) are measured.
