Abstract
Methods of using nanohybrid-containing fluids in a well are provided. The methods include the steps of: (a) forming or providing a well fluid comprising a nanohybrid; and (b) introducing the well fluid into a well. The methods can be used in various applications, such as in drilling, completion, or intervention operations.
Claims18
A method of altering the wettability of a surface in a well, the method comprising the steps of:
- (a) providing a well fluid comprising a nanohybrid comprising a carbon nanotube attached to a hydrophilic inorganic second component;
- and
- (b) introducing the well fluid into a well to contact the surface, wherein the contact angle of water on the surface is altered at least 10°.
A method of altering the wettability of a surface in a well, the method comprising the steps of:
- (a) providing a well fluid comprising a nanohybrid comprising a carbon nanotube attached to a hydrophilic inorganic second component;
- and
- (b) introducing the well fluid into a well to contact the surface, wherein the contact angle of an oil on the surface is altered at least 10°.
