Zusammenfassung:	Disclosed are compositions for drilling and/or maintaining a wellbore, e.g., drilling fluids and drilling muds, comprising oleaginous yeast. The oleaginous yeast may comprise at least about 45 wt % oil. The oleaginous yeast may comprise a genetic modification that either increases the oil content of the yeast, alters the lipid composition of the yeast, and/or provides a selective advantage for the yeast, e.g., relative to an unmodified yeast of the same species.
