Beschreibung
Zusammenfassung:	The present invention generally relates to emulsifiers for oil-based drilling fluids and muds comprising an emulsifierbased on the polyamides derived from fattyacid/carboxylic acidand optionally alkoxylated polyamines.The invention alsorelates to oil or synthetic based drilling fluids comprising the emulsifiers of the invention and todrilling methods utilizing same. La présente invention concerne de manière générale des émulsifiants pour fluides et boues de forage à base d'huile, qui comprennent un émulsifiant à base de polyamides dérivés d'acide gras/acide carboxylique et éventuellement de polyamines alcoxylées. L'invention concerne également des fluides de forage synthétiques ou à base d'huile qui comprennent les émulsifiants de l'invention, ainsi que des procédés de forage les utilisant.
