摘要:
Methods for drilling a wellbore into a subterranean formation include preparing a drilling fluid and circulating the drilling fluid in the wellbore while drilling in the subterranean formation, forming a filtercake from the drilling fluid, creating or encountering one or more fractures in the subterranean formation while drilling, and allowing a portion of the filtercake formed to at least partially seal the one or more fractures while continuing the drilling.
