Title
(EN) OIL-BASED FLUID LOSS COMPOSITIONS
(FR) COMPOSITIONS DE CONTRÔLE DE PERTE DE FLUIDE À BASE D'HUILE
Abstract
(EN) Compositions with modified tannins can be used in wellbore operations. A composition can include an oil, a modified tannin, a dimer fatty acid, an aqueous liquid, and an emulsifier, where the material is injectable into a wellbore. The modified tannin may be treated with a primary amine, secondary amine, tertiary amine, or quaternary amine. The compositions may be used as drilling fluids having enhanced yield point and fluid loss control properties.
(FR) Des compositions ayant des tanins modifiés peuvent être utilisées dans des opérations de puits de forage. Une composition peut comprendre une huile, un tanin modifié, un acide gras dimère, un liquide aqueux et un émulsifiant, le matériau étant injectable dans un puits de forage. Le tanin modifié peut être traité avec une amine primaire, une amine secondaire, une amine tertiaire ou une amine quaternaire. Les compositions peuvent être utilisées comme fluides de forage ayant des propriétés de contrôle de perte de fluide et de limite d'écoulement améliorées.
