Patent number: 8297380Abstract: Casing shoes comprise a nose portion having an inner profile and an outer profile. At least one cutting structure is on the outer profile. A stem section extends longitudinally from the nose portion. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is disposed within the stem section. Methods of installing sections of casing within wellbores comprise advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is carried within the casing shoe into the wellbore. The wellbore is drilled or reamed using at least one cutting structure on the casing shoe as the at least one section of casing is advanced into the wellbore.Type: GrantFiled: July 7, 2011Date of Patent: October 30, 2012Assignee: Baker Hughes IncorporatedInventors: Jack T. Oldham, L. Allen Sinor, Eric E. McClain, Robert A. Laing, Evan C. Turner, Mark W. Dykstra, Eric C. Sullivan
