Title (EN) EMULSIFIERS FOR INVERT EMULSION WELLBORE FLUIDS AND METHODS OF USE THEREOF
(FR) ÉMULSIFIANTS POUR LIQUIDES DE PUITS DE FORAGE EN ÉMULSION INVERSE ET LEURS PROCÉDÉS D'UTILISATION
Abstract:
(EN) A wellbore fluid may include an oleaginous external phase, a non-oleaginous internal phase and a reaction product of a capping agent with a base emulfisifer, the base emulsifier being a reaction product of a fatty acid and a hydrophilic compound having at least two reactive hydrophilic functional groups, the capping agent being selected from the group consisting of a polycarboxylic acid, anhydride, urea, isocyanate, alpha-halocarboxylic acid, oxirane, cyclic diester, and cyclic sulfonate ester.
(FR) La présente invention décrit un liquide de puits de forage pouvant comprendre une phase externe oléagineuse, une phase interne non oléagineuse et un produit réactionnel d'un agent de coiffage avec un émulsifiant de base, l'émulsifiant de base étant un produit réactionnel d'un acide gras et d'un composé hydrophile ayant au moins deux groupes fonctionnels hydrophiles réactifs, l'agent de coiffage étant sélectionné dans le groupe constitué du poly(acide carboxylique), d'un anhydride, d'urée, d'isocyanate, d'acide alpha-halogénocarboxylique, d'oxirane, de diester cyclique, et d'ester sulfonate cyclique.
