Abstract

A method for achieving zonal control in a wellbore when using casing or liner drilling includes providing a slotted tubular section in a wellbore while drilling; providing a sleeve adjacent to and radially overlapping with the slotted tubular section, while drilling; and moving the sleeve relative to the slotted tubular section so as to permit and/or restrict flow through the slotted tubular section in one or more selected zones.
