Beschreibung
Zusammenfassung:	A method of drilling a subterranean well may include drilling the subterranean well while circulating a wellbore fluid in the subterranean well, wherein the wellbore fluid includes a base fluid; and a ground weight material comprising barite and quartz and having a d50 between about 4 and 8 microns and a d90 between about 15-25 microns. La présente invention concerne un procédé de forage d'un puits souterrain qui peut comprendre le forage du puits souterrain tout en faisant circuler un fluide de puits de forage dans le puits souterrain, le fluide de puits de forage comprenant un fluide de base ; et un matériau alourdissant broyé comprenant de la barite et du quartz et possédant un d50 compris entre environ 4 et 8 micromètres et un d90 compris entre environ 15 et 25 micromètres.
