Abstract

In one aspect, a complex emulsion includes an internal fluid-in-gas emulsion configured to increase a density and a viscosity of a gas in the internal fluid-in-gas emulsion emulsifying a fluid in the internal fluid-in-gas emulsion. The complex emulsion includes an external fluid emulsifying the internal fluid-in-gas emulsion, and the external fluid is configured to carry corrosion inhibitors into a subterranean zone. The complex emulsion includes hydrophobic particles encapsulating an outer surface of droplets of the fluid in the internal fluid-in-gas emulsion. A concentration of the hydrophobic particles is between about 0.1% and 0.5% by weight.
