Abstract
An aqueous drilling fluid is flowed from a surface location through a drill string and into a wellbore formed in a subterranean formation. The aqueous drilling fluid includes bentonite and a synthetic clay. While flowing the aqueous drilling fluid, a drill bit coupled to the drill string is rotated within the wellbore, thereby cutting into the subterranean formation and elongating the wellbore. The drilling fluid from the wellbore is received at the surface location.
