Carbonate rock formation surfactant injection method

An oil recovery method from a carbonate rock formation, comprising:

• injecting a mixture into the carbonate rock formation comprising an oil composition, wherein the injecting is through a first wellbore connected to the carbonate rock formation;
• and
• extracting the oil composition from the carbonate rock formation, wherein the extracting is through a second wellbore connected to the carbonate rock formation,
• wherein the mixture comprises 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, and
• wherein 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.
