Claims12
A method of using a nanohybrid-stabilized foam in a well, wherein the method comprises the steps of:
- (a) forming a foam comprising:
- (i) a nanohybrid comprising a carbon nanotube attached to a hydrophilic inorganic second component;
- (ii) a liquid phase, wherein the liquid phase is an oil-based liquid;
- and
- (iii) a gaseous phase;
- (b) introducing a well fluid comprising the foam into the well.
