Title (EN) SPACER FLUID COMPOSITIONS THAT INCLUDE SURFACTANTS
(FR) COMPOSITIONS DE FLUIDE D'ESPACEMENT CONTENANT DES TENSIOACTIFS
Abstract:
(EN) In one embodiment, a spacer fluid may comprise a base fluid and a surfactant package. The surfactant package may comprise one or more surfactants, where the surfactant package comprises a first surfactant having the chemical structure R — (OC2H4)x―OH. R may be a hydrocarbyl group having from 9 to 20 carbon atom, and x may be an integer from 5 and 15. The first surfactant may have a hydrophilic-lipophilic balance (HLB) of from 12 to 13.5.
(FR) Dans un mode de réalisation, l'invention concerne un fluide d'espacement pouvant comprendre un fluide de base et un ensemble de tensioactifs. L'ensemble de tensioactifs peut comprendre au moins un tensioactif, ledit ensemble comprenant un premier tensioactif présentant la structure chimique R — (OC2H4)x―OH. R peut être un groupe hydrocarbyle contenant de 9 à 20 atomes de carbone et x peut être un nombre entier compris entre 5 et 15. Le premier tensioactif peut présenter un équilibre hydrophile-lipophile (HLB) compris entre 12 et 13,5.
