Process for producing mineral oil using surfactants based on a mixture of c32 guerbet-, c34 guerbet-, c36 guerbet-containing alkyl alkoxylates |
| abstract |
The invention relates to a method for producing mineral oil by means of Winsor Type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises, in relation to the alkyl part (R1)(R2)-CH-CH2-, at least three different ionic surfactants of general formula (R1)(R2)-CH-CH2-0-(D)n-(B)m-(A)1-XY a-a/b M b+ is pressed though injection wells into a mineral oil deposit and crude oil is extracted from the deposit via production wells. The invention also relates to surfactants formulations of ionic surfactants according to the general formula. |
