Abstract:
A shoe track assembly system includes an elongated casing body extending from a first end to a second end and having a guide nose engaged with the second end; a first valve secured within the elongated casing body and at a position directly above the guide nose; a bottom plug landing seat extending into the elongated casing body at a position above the first valve; and a top plug landing seat extending into the elongated casing body at a position above the bottom plug landing seat; the system is to receive casing pressure test and act as a wall barrier system preventing cement or formation fluid from entering the casing without relying on shoe track cement integrity.
