1. A method comprising:
injecting a proppant sample into a vessel wherein, the vessel compacts the proppant sample inside the vessel;
applying pressure on a proppant surface of the proppant sample by a flat surface to reduce spaces between particles of the proppant sample, such that the proppant surface is level;
applying a droplet of deionized water or a hydrocarbon onto the level proppant surface; and
capturing an image of the droplet contacting the proppant sample to provide a wettability assessment of the proppant sample.
