Limitless injection shoe

A method for cementing a casing string in a wellbore, the method comprising:

• deploying the casing string into the wellbore, the casing string providing a flow path and including:
• a shoe track at a lower end of the casing string;
• an annular isolation apparatus arranged uphole from the shoe track and including a seal member;
• and
• a communication tool arranged uphole from the annular isolation apparatus;
• landing a first isolation device within the casing string and thereby forming a seal within the flow path below the annular isolation apparatus and isolating the shoe track from the annular isolation apparatus and the communication tool;
• radially expanding the seal member and thereby forming a seal within an annulus defined between the casing string an inner wall of the wellbore, and thereby fluidly isolating the annulus above the seal member from a toe of the wellbore;
• opening at least one radial port defined in the communication tool to establish fluid communication between the flow path above the first isolation device and the annulus above the seal member;
• circulating a cement slurry through the flow path and the at least one radial port to be received within the annulus above the seal member;
• activating a bypass mechanism of the first isolation device to permit flow through the first isolation device;
• pumping a deactivation fluid through the bypass mechanism to the shoe track and through an opening in the shoe track to be received within the toe of the wellbore while the toe of the wellbore is fluidly isolated from the annulus above the seal member;
• landing a third isolation device within the casing string at the communication tool;
• and
• placing a hydraulic load on the third isolation device and thereby causing a barrier member to transition from a retracted position, where the barrier member does not obstruct the flow path, to an extended position, where the barrier member extends across the flow path.
