Beschreibung
Zusammenfassung:	A method of minimizing the weight loss of mass of the drilling pipe and wellbore casing while drilling a subterranean well with an oil-based drilling fluid comprising adding to the oil-based drilling fluid an anti-wear additive based on sulfated, sulfonated or sulfited natural oils or fats of vegetable or animal origin. La présente invention concerne un procédé de réduction au minimum de la perte de poids de la masse du tube de forage et du tubage de puits de forage pendant le forage d'un puits souterrain avec un fluide de forage à base d'huile consistant à ajouter au fluide de forage à base d'huile un additif anti-usure à base d'huiles naturelles ou de graisses d'origine végétale ou animale sulfatées, sulfonées ou sulfitées.
