Title (EN) CATIONIC MULTIPLE QUATERNARY AMMONIUM-BASED SURFACTANTS FOR ENHANCING PRODUCTION IN SUBTERRANEAN FORMATIONS
(FR) TENSIOACTIFS CATIONIQUES À BASE DE MULTIPLES AMMONIUMS QUATERNAIRES POUR L'AUGMENTATION DE LA PRODUCTION DANS DES FORMATIONS SOUTERRAINES
Abstract: front page image
(EN)Surfactant compositions for enhancing oil and/or gas production from certain subterranean formations (e.g., unconventional reservoirs), and related methods of use, are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising a carrier fluid and a cationic surfactant comprising at least two hydrophobic heads that each comprise a quaternary cationic moiety; and introducing the treatment fluid into at least a portion of a subterranean formation.
(FR)L'invention porte sur des compositions de tensioactif pour l'amélioration de la production de pétrole et/ou de gaz à partir de certaines formations souterraines (par exemple des gisements non classiques) et sur des procédés d'utilisation s'y rapportant. Dans un mode de réalisation, le procédé comprend : l'utilisation d'un fluide de traitement comprenant un fluide vecteur et un tensioactif cationique comprenant au moins deux têtes hydrophobes qui comprennent chacune une fraction cationique quaternaire; et l'introduction du fluide de traitement dans au moins une partie d'une formation souterraine.
