A plug for use in wellbore operations includes a plug body extending from a top end to a bottom end; a sealing member as part of the plug body and positioned at the bottom end; and a non-rotating profile positioned at the bottom end of the plug body; the sealing member protrudes past the non-rotating profile such that the sealing member comes into contact with a surface when the plug is dropped into a well before the non-rotating profile.

A casing pressure test tool assembly includes a well extending from a top end to a downhole end, the well having a receptacle; a wireline tool to run into the well; a casing test plug positioned downhole of the wireline tool, the casing test plug having a plug body extending from a first end to a second end; and a wireline setting tool adapter connecting the wireline setting tool and the casing test plug; the casing test plug releases from the wireline setting tool upon application of a separation force between the wireline setting tool adapter and the plug body; the casing test plug seals within the receptacle of the well; and the casing test plug, once sealed within the receptacle, allows for casing pressure testing operations of the well.

A shoe track assembly system includes an elongated housing extending from a first end to a second end; one or more valves secured within the elongated housing; one or more plug landing seats extending into the elongated housing; one or more plugs to be dropped into the elongated housing and engage with the one or more plug landing seats; the system is to receive casing pressure testing without relying on a shoe track cement integrity; and the system is to contain all required shoe track equipment as required by an operation.

A wellbore system includes a first plug and a second plug that latch independently within an elongated housing; at least one plug having an elongated channel with a ball therein for performing operation of a pressure test; and optionally including a ball seat for receiving a dissolving ball for contingency and supplementary casing tests.

A system for establishing a bypass flow path includes a plug assembly having bypass ports extending from the exterior to the interior; a wiper dart to engage and seal the first flow path and bypass flow path, and initiate release of the plug assembly from a first position, the plug assembly having a dart nose attached to the dart body; once the plug has moved to a second position, pressure applied through the bypass ports communicates to the dart nose to cause detachment of the dart nose from the dart body; a first flow path extends through the central bore of the plug assembly when the wiper dart is not present; and a second flow path extends through the bypass ports on the plug assembly below the dart body to the detachable dart nose, once detached, the bypass flow path is established thru the bore below the dart body.

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.

An erosion resistant check valve includes a valve housing having a fluid flow passage extending therethrough; a valve seat extending within the fluid flow passage; a valve member slidingly engaged within the fluid flow passage; a spring engaged with the valve stem to contract upon pressure towards the stop; a housing positioned over the first end of the valve stem and past the stop, the housing creating a gap between a portion of the stem body and an inner surface of the housing; the spring contracts into the housing and the disk is seals the spring within the housing to prevent fluid contact therewith.
