Abstract
Drilling assemblies include a drill bit and a reamer apparatus in which the drill bit is configured to rotate in rotational direction about a longitudinal axis of a drill string and the reamer apparatus is configured to rotate in an opposite rotational direction about the longitudinal axis. Methods of forming a drilling assembly include configuring a drill bit to drill a subterranean formation when rotating in a counter-clockwise direction and configuring a reamer apparatus to ream a wellbore within the subterranean formation when rotating in a clockwise direction. Methods of drilling wellbores in subterranean formations include rotating a drill bit in a first rotational direction about a longitudinal axis of a drill string to drill a wellbore and rotating a reamer apparatus in an opposite rotational direction about the longitudinal axis of the drill string to ream the wellbore.
