A method for enhanced oil recovery from a low permeability diatomaceous reservoir by imbibition is described. In this method, oil is displaced from a single injection well, or series of injection wells into a single producer or series of producing wells by a combination of applied fluid pressure, plus "enhanced imbibition." Enhanced imbibition is accomplished by adding chemical additives to the injection fluid so that rock in the tight reservoir has a stronger affinity for the water present therein, thus releasing oil from the rock.
