Abstract

Fremgangsmåte for syrehandling av en underjordisk formasjon involverer anvendelsen av en sammensetning som inneholder en løsning av en viskoelastisk amidoaminoksid surfaktant og en HF-holdig syrebehandlingsløsning. Sammensetningen inneholder typisk fra omkring 0,1 til omkring 8 vektprosent surfaktantløsning og fra omkring 92 til omkring 99,9 vektprosent HF-holdig syrebehandlingsløsning. Sammensetningen pumpes inn i den underjordiske formasjonen. Ettersom syren reagerer, fortykkes sammensetningen og blir et selv-avledende middel dannet in-situ. Når syren forbrukes ytterligere, avtar fluidviskositeten og returnerer til slutt til en tilstand med lav viskositet, hvilket tillater enkel opprensing. Fremgangsmåten tillater selektiv syrebehandling av mindre permeable soner i formasjonen og mer enhetlig stimulering av den hydrokarbonholdige formasjonen.Method of acid treating an underground formation involves the use of a composition containing a solution of a viscoelastic amido amine oxide surfactant and an HF-containing acid treatment solution. The composition typically contains from about 0.1 to about 8 weight percent surfactant solution and from about 92 to about 99.9 weight percent HF-containing acid treatment solution. The composition is pumped into the underground formation. As the acid reacts, the composition thickens and a self-conducting agent is formed in situ. As the acid is further consumed, fluid viscosity decreases and eventually returns to a low viscosity state, allowing easy purification. The process allows selective acid treatment of less permeable zones in the formation and more uniform stimulation of the hydrocarbon-containing formation.
