Comparative experiments on the wettability within the framework of absolute and effective pore space concepts

Authors: S.N. Zakirov, A.Sh. Murtazaliev (Oil and Gas Research Institute of RAS)
Laboratory studies on artificial dry cores and on the same cores with residual water saturation were performed. Artificial cores consisted of cemented sandstone samples with different content of cement, i.e., differed in reservoir properties. The method of research execution is considered. It is established that the experiments based on the concept of absolute pore space can lead to incorrect qualitative conclusions, as well as low correlation coefficients of petrophysical relationships or significant errors in parameters determining.
