A cutting element for use in a drill bit for drilling subterranean formations includes a cutting body having a substrate, and a superabrasive layer overlying an upper surface of the substrate. The cutting element further includes a sleeve including another superabrasive layer and surrounding the peripheral side surface of the cutting body.

Cutting elements for drill bits for drilling subterranean formations and methods of forming such cutting elements

A cutting element for use in a drill bit for drilling subterranean formations includes a cutting body having a substrate including a rear surface, an upper surface, and a peripheral side surface extending between the rear surface and the upper surface, and a superabrasive layer overlying the upper surface of the substrate. The cutting element further includes a sleeve surrounding the peripheral side surface of the cutting body and comprising a superabrasive layer bonded to an external surface of the sleeve.

Methods, systems, and tool assemblies for distributing weight between a bit and a reamer device are disclosed. For example, at least one of the drill bit and the reamer may be configured to selectively distribute a weight-on-bit between the drill bit and the reamer, such as within a predetermined range. Additionally, methods of drilling wellbores may include selectively distributing a weight-on-bit applied to a bottom hole assembly between a drill bit and a reamer of the bottom hole assembly. Also, a reamer may be configured to exhibit a first maximum rate-of-penetration into a relatively hard formation, and a drill bit may be configured to exhibit a second maximum rate-of-penetration into a relatively soft formation that is less than the first maximum rate-of-penetration.
