Drop-In Check Valves serve to prevent upward flow through the drill string while permitting downward mud pumping or flow. Drilling Contractors are constantly seeking means to improve well control. Even though a well is equipped with a blowout preventer to block the annular space between the casing and the drill string, full protection is not available to close off the fluid passage through the drill pipe in case of a kick. The Check Valve is installed by dropping it into an open tool joint and pumping it down to engagement into the Landing Sub.
