Abstract
Utførelser av foreliggende oppfinnelse omhandler et reversibelt fortykkbart ikke-polymert fluid som har lav viskositet i en sterk syre, gelatinerer når syrekonsentrasjonen reduseres bare med en liten mengde og deretter dekomponeres av syren. Spesielt omhandler den en vandig blanding av zwitterioniske surfaktanter, uorganiske syrer og organiske syrer. Mest spesielt omhandler den anvendelsen av dette fluidet som et avledningsmiddel for lett-skadede sandsteiner, for eksempel før matrikssyrebehandling.Embodiments of the present invention disclose a reversibly thickable non-polymeric fluid having low viscosity in a strong acid, gelatinizing when the acid concentration is reduced only by a small amount and then decomposed by the acid. In particular, it deals with an aqueous mixture of zwitterionic surfactants, inorganic acids and organic acids. Most notably, it deals with the use of this fluid as a diversion agent for lightly damaged sandstones, for example before matrix acid treatment.
