Nanoparticle design for enhanced oil recovery

Abstract

The present invention relates generally to hydrocarbon recovery, and more particularly, a method of designing a nanoparticle tailored to support hydrocarbon recovery in a subterranean formation, a method for using nanoparticles to extract hydrocarbon from a subterranean formation, and a nanoparticle structure. Embodiments may include determining environmental conditions of a subterranean formation, defining nanoparticle parameters based on the environmental conditions, and forming a nanoparticle comprising the nanoparticle parameters. Embodiments may include producing a colloidal suspension of nanoparticles by mixing nanoparticles with water and injecting the colloidal suspension of nanoparticles into a subterranean formation. A nanoparticle structure may include a hydrophilic material in a defined three-dimensional shape having a maximum diameter. The nanoparticle may penetrate through an oil-water interface with an optimized contact angle, minimize an interfacial area between oil and water, and create an oil in water emulsion.
