ABSTRACT
Wetting states induced by crude oil at mineral surfaces initially covered with brine are of special importance to oil recovery by waterflooding. This paper mainly concerns the wetting changes that occur when a crude oil-brine interface is brought into very close proximity to the interface formed by a quartz surface covered with brine. The properties of the two interfaces can have a dominant control on the subsequent changes in wetting caused by the adsorption of polar components from the crude oil onto the quartz surface [1].
