Abstract: 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.

Abstract: An invert emulsion fluid may include a oleaginous external phase, a nonoleaginous internal phase, wherein a ratio of the oleaginous external phase to nonoleaginous internal phase is less than 55:45, a emulsifier, a particulate weighting agent dispersed in the non-oleaginous internal phase, and a viscosifier stabilizing the dispersion of the particulate weighting agent in the non-oleaginous internal phase.
