Abstract
A method of extracting oil from a subsurface reservoir includes the steps of accessing the subsurface reservoir by means of a well, injecting a waterflooding composition comprising water and a functional molecule, into the subsurface reservoir through the well, altering the interfacial viscoelasticity, and extracting the oil through the well.
Claims10
A method of extracting oil from a subsurface reservoir, the method consisting essentially of:
- accessing the subsurface reservoir by means of a well;
- injecting a waterflooding composition comprising water and a functional molecule, into the subsurface reservoir through the well, wherein the functional molecule is selected from a demulsifier or a surfactant or combinations thereof, and wherein the functional molecule comprises an ethoxylate resin;
- altering the interfacial viscoelasticity of the oil and water;
- and
- extracting the oil through the well.
