1. A method of treating a gas condensate reservoir comprising a porous formation material, the method comprising:
- introducing a formation treatment fluid to the gas condensate reservoir, wherein the gas condensate reservoir comprises condensate in contact with the porous formation material, and the formation treatment fluid is a dispersion comprising;
metal oxide nanoparticles; and
at least one additive selected from a group consisting of xanthan gum, partially hydrolyzed polyacrylamide, sodium hexadecyl diphenyl oxide disulfonate, hydrochloric acid, sodium hydroxic, and stearic acid; and
maintaining the formation treatment fluid in the gas condensate reservoir, such that at least a portion of the condensate is displaced from the porous formation material to yield free condensate in the gas condensate reservoir.

Abstract
Treating a gas condensate reservoir having a porous formation material includes introducing a formation treatment fluid to the gas condensate reservoir and maintaining the formation treatment fluid in the gas condensate reservoir. The formation treatment fluid is a dispersion including metal oxide nanoparticles, and the gas condensate reservoir includes discrete portions of condensate in contact with the porous formation material.
