Method of enhanced oil recovery in a carbonate rock formation

A method of enhanced oil recovery in a carbonate rock formation including, injecting a mixture into the carbonate rock formation containing an oil composition, and extracting the oil composition from the carbonate rock formation. The mixture contains 89-98.9 vol % of an aqueous solution, 0.01-1 vol...

Beschreibung
Zusammenfassung:	A method of enhanced oil recovery in a carbonate rock formation including, injecting a mixture into the carbonate rock formation containing an oil composition, and extracting the oil composition from the carbonate rock formation. The mixture contains 89-98.9 vol % of an aqueous solution, 0.01-1 vol % of a gemini cationic surfactant, and 0.1-10 vol % of formic acid based on a total volume of the mixture. During the injecting at least a portion of the gemini cationic surfactant is adsorbed onto the carbonate rock formation, and wherein at least 90% less by volume of the gemini cationic surfactant adsorbs onto the carbonate rock formation compared to a method under the same conditions but without the formic acid.
