Title (EN) AMIDO- FUNCTIONALIZED GEMINI SURFACTANT FOR FLUID CONTROL IN SUBTERRANEAN FORMATIONS
(FR) TENSIOACTIF GÉMINÉ À FONCTION AMIDO POUR RÉGULER LES FLUIDES DANS DES FORMATIONS SOUTERRAINES
Abstract: front page image
(EN)Controlling fluid flow in a subterranean formation containing water and hydrocarbons utilizing a Gemini surfactant introduced to the formation via a wellbore. The Gemini surfactant includes a head group having two cationic groups linked by an alkyl spacer, an amide extending from each of the cationic groups, and each amide having a hydrophobic tail extending therefrom.
(FR)Cette invention concerne la régulation de l'écoulement des fluides dans une formation souterraine contenant de l'eau et des hydrocarbures faisant appel à un tensioactif géminé introduit dans la formation par l'intermédiaire d'un trou de forage. Le tensioactif géminé contient un groupe de tête comportant deux groupes cationiques liés par un espaceur alkyle, un amide s'étendant depuis chacun des groupes cationiques, chaque amide étant doté d'une queue hydrophobe s'étendant à partir de celui-ci.
