ABSTRACT:
A casing shoe for a casing string that includes an annular body. The annular body includes an annular recess that forms an outer portion and an inner portion, the inner portion forming and extending into an inner bore. The annular recess can accept an end of the casing string such that the casing string extends between the inner and outer portions. The annular body includes a homogenous material. The casing shoe is used in a method of guiding a casing string into a wellbore where the casing shoe is attached to an end of the casing string. Attaching the casing string includes inserting the end of the casing string into the annular recess such that the casing string extends between the inner and outer portions. The casing string is then inserted into the wellbore.
