Abstract
One methods for in-situ characterization of a reservoir rock includes: (a) sealing an interval corresponding to a selected depth or depths within the subterranean formation; (b) injecting a displacement fluid into the interval, wherein the displacement fluid displaces a reservoir fluid stored in the reservoir rock; (c) monitoring movement of the displacement fluid or the reservoir fluid in the reservoir rock; and (d) assessing wettability of the reservoir rock based on (c) or determining recovery rate of the reservoir fluid.
