Beschreibung
Zusammenfassung:	A water-based wellbore fluid including an aqueous fluid, a mixed metal oxide-clay complex, and an anionic sup-pressant, where the anionic suppressant includes a Lewis acid and a lubricant and where the lubricant includes a sulfur containing compound and at least one pH agent, where the at least one pH agent is in an amount sufficient to obtain a pH ranging from about 9 to 13 is disclosed. La présente invention concerne un fluide de forage à base d'eau comprenant un fluide aqueux, un complexe oxydes métalliques mélangés/argile, et un suppresseur anionique, le suppresseur anionique comprenant un acide de Lewis et un lubrifiant et le lubrifiant comprenant un composé soufré et au moins un tampon, le ou les tampons étant en quantité suffisante pour obtenir un pH dans la plage allant d'environ 9 à 13.
