Abstract
A liner drilling system and method to at least partially drill a wellbore with a liner and cement the liner in place in the wellbore, in a single downhole trip. An example system includes a liner releasably coupled to a drill string. The drill string extends through an axial bore of the liner and a downhole end includes a bottomhole assembly and a drill bit that rotate to drill a portion of a wellbore. A liner annulus is formed between the drill string and the liner. An annulus isolator is coupled to the liner and isolates flow within the bore of the liner from flowing through at least a portion of a wellbore annulus between the liner and the wellbore. A diverter in the drill string is positioned uphole of the bottomhole assembly and establishes a cement flow path into the liner annulus.
