Abstract
Methods of using nanohybrid-stabilized emulsions in a well are provided that include the steps of: (a) forming an emulsion comprising: (i) a nanohybrid; (ii) water or an aqueous solution; and (iii) a water-immiscible liquid; (b) introducing a well fluid comprising the emulsion into a well; and (c) after the step of introducing, modifying the nanohybrid to break the emulsion in the well. The methods can be used in various applications, such as in drilling, completion, or intervention operations.
Claims26
A method of using a nanohybrid-stabilized emulsion in a well, wherein the method comprises the steps of:
- (a) forming an emulsion comprising:
- (i) a nanohybrid comprising a carbon nanotube attached to a hydrophilic inorganic second component;
- (ii) water or an aqueous solution;
- and
- (iii) a water-immiscible liquid;
- (b) introducing a well fluid comprising the emulsion into the well;
- and
- (c) after the step of introducing, modifying the nanohybrid to break the emulsion in the well.
