A check enhancer for use in a well comprises a housing portion and an injector portion disposed in the housing portion. The housing portion includes an outer body defining a fluid cavity therein with a plurality of body ports in communication with the fluid cavity. The injector portion includes a check valve and a dispersement nipple in communication therewith. The check valve is connected to the outer body, and the dispersement nipple extends into the fluid cavity. The check valve allows fluid flow from the tubing through nipple ports defined in the dispersement nipple. The nipple ports are longitudinally spaced from the body ports so that the fluid cavity remains substantially filled with fluid with the dispersement nipple substantially submerged within the fluid.
