Abstract
The invention discloses a method for determining the wettability of an underground formation traversed by a borehole, the method comprising: determining the critical water fraction of the underground formation; determining the critical water fraction of the underground formation taken entirely oil-wet, which is called the oil-wet critical water fraction; and combining the critical water fraction and the oil-wet critical water fraction in order to determine the wettability of the underground formation.
