    摘要: A drill bit is provided that employs a plurality of discrete, post-like, abrasive, particulate-impregnated cutting structures extending upwardly from the bit face. The cutting structures may be disposed on abrasive, particulate-impregnated blades that also define a plurality of fluid passages on the bit face. One or more of the cutting structures may include outermost ends that exhibit a cross-sectional geometry that is elongated in a direction along a defined axis. The cutting structures may be oriented such that the defined axis is neither coplanar with, nor parallel to, an intended rotational path of the at least one discrete cutting structure during operation of the bit. In one embodiment, the cutting structure is oriented such that the defined axis is at an acute angle relative to a tangent of the intended rotational path for the associated cutting structure. Other or different features may include, for example, additional, differently configured cutting elements.

    摘要: 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.
