Abstract

i. Fremgangsmåte for utvinning av olje fra en underjordisk foraasJon er beskrevet, hvor en vandig oppløsning av et overflateaktlvt middel Injiseres 1 formasjonen for å redusere gassens mobilitet 1 en gass-flømmeprosess. Gassen kan omfatte hydrokarbongass, inertgass, karbon-dloksyd og damp. Det overflateaktlve middelet er representert ved den generelle formel:. hvor E er en alkylgruppe med lineær eller forgrenet kjede med n karbonatomer, bvor n varierer fra 0 til ca. 18, bortsett fra at dersom gassen er damp, varierer n fra ca. 9 til ca. 30,. z varierer fra 0 til ca. 20. og y varierer fra 0 til ca. 20, forutsatt ati+j* Ikke overstiger ca. 20,. £' er en alkylgruppe med lineær eller forgrenet kjede med D karbonatomer, bvor m varierer fra 0 til 4. bortsett fra at dersom gassen er damp, varierer m fra 1 til 4, med det forbehold at summen x + y + m er minst 1, og hvert Mer et kation.i. A method of recovering oil from a subterranean deposition is described, in which an aqueous solution of a surfactant is injected into the formation to reduce the mobility of the gas in a gas-flow process. The gas may include hydrocarbon gas, inert gas, carbon dioxide and steam. The surfactant is represented by the general formula :. where E is a linear or branched chain alkyl group having n carbon atoms, wherein n varies from 0 to approx. 18, except that if the gas is steam, n varies from approx. 9 to approx. 30 ,. z varies from 0 to approx. 20. and y varies from 0 to approx. 20, provided ati + j * Does not exceed approx. 20 ,. £ 'is an alkyl group with a linear or branched chain with D carbon atoms, where m varies from 0 to 4. except that if the gas is vapor, m varies from 1 to 4, provided that the sum x + y + m is at least 1 , and each More a cation.
