1. An autonomous inflow control device, comprising:
a body defining a cavity;
an inlet in fluid communication with the cavity, wherein the inlet receives well fluids;
a deflection surface within the cavity, wherein the well fluids deflect off the deflection surface at an angle based on a predetermined fluid property range of the well fluids;
an influx outlet in fluid communication with the cavity;
an actuation device disposed in the cavity, wherein based on the angle the well fluids deflect off the deflection surface, the actuation device moves between an open position and a closed position,
wherein when the actuation device is in the closed position, the actuation device covers the influx outlet,
wherein when the actuation device is in the open position, the actuation device exposes the influx outlet to direct a volume of water from the well fluids out of the cavity; and
an outlet in fluid communication with the cavity, wherein the outlet directs the well fluids out of the cavity.
