Casing and liner drilling shoes having integrated operational components, and related methods

A casing shoe configured for attachment to a section of casing and for drilling or reaming a wellbore as the section of casing is advanced into contact with subterranean formation material, the casing shoe comprising:

• a nose portion having an inner profile and an outer profile;
• at least one cutting structure on the outer profile of the nose portion, the at least one cutting structure configured for removing formation material;
• a stem section extending longitudinally from the nose portion;
• and
• at least one device selected from a group consisting of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure disposed within the stem section;
• wherein the casing shoe further comprises at least one portion configured to fail in response to increased pressure within the casing shoe;
• wherein the at least one portion of the casing shoe configured to fail is located on a lateral side of the casing shoe.

• wherein the at least one portion of the casing shoe comprises at least one of a frangible region of the casing shoe and a perforable region of the casing shoe.

A method of installing at least one section of casing within a wellbore, comprising:

• advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto;
• drilling or reaming the wellbore using at least one cutting structure as the at least one section of casing is advanced into the wellbore;
• increasing the flow of fluid through at least one aperture extending through a nose portion of the casing shoe;
• and
• causing at least one portion of the casing shoe to fail with said increasing the flow.

A method of installing at least one section of casing within a wellbore, comprising:

• advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto;
• carrying at least one device selected from a group consisting of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure within the casing shoe into the wellbore;
• and
• drilling or reaming the wellbore using at least one cutting structure on the casing shoe as the at least one section of casing is advanced into the wellbore;
• increasing a pressure within the casing shoe;
• and causing at least one portion of the casing shoe to fail responsive to the increased pressure within the casing shoe;
• wherein increasing the pressure within the casing shoe comprises increasing the flow of fluid through at least one aperture extending through a nose portion of the casing shoe.

A method of installing at least one section of casing within a wellbore, comprising:

• advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto;
• carrying at least one device selected from a group consisting of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure within the casing shoe into the wellbore;
• and
• drilling or reaming the wellbore using at least one cutting structure on the casing shoe as the at least one section of casing is advanced into the wellbore;
• increasing a pressure within the casing shoe;
• and causing at least one portion of the casing shoe to fail responsive to the increased pressure within the casing shoe;
• further comprising flowing cement through the at least one portion of the casing shoe after causing the at least one portion of the casing shoe to fail responsive to the increased pressure within the casing shoe.
