Method for producing crude oil using cationic surfactants comprising a hydrophobic block having a chain length of 6 - 10 carbon atoms |
| abstract |
The invention relates to a method for producing crude oil by means of Winsor type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises at least one ionic surfactant of general formula R1 N+ (R2)m (R3)n (R4) X- is forced through injection wells into a mineral oil deposit and crude oil is withdrawn from the deposit through production wells. |
