Abstract: Methods and systems for in-situ characterization of a reservoir rock are provided. One method 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.

Abstract: Methods of combining mineral composition and laboratory test results for reservoir rock samples to predict future responses to secondary and tertiary oil recovery treatments are disclosed. Particular, SEM and EDS will be combined to produce a mineral map, including mineral distribution around the rock's pore space, for comparison with laboratory data to predict and/or interpret how certain mineral distributions will respond to various fluid-rock interactions.
