Abstract
A method for reducing condensate in a subsurface formation is disclosed. The method comprises introducing a first reactant and a second reactant into the subsurface formation. The first reactant and the second reactant produce an exothermic reaction that increases temperature and pressure in the subsurface formation to greater than a dew point of the condensate. Increasing the temperature and pressure in the subsurface formation to greater than the dew point of the condensate vaporizes, and thereby reduces, condensate in the subsurface formation.

A method for reducing condensate in a subsurface formation, the method comprising:
- introducing a first reactant and a second reactant into the subsurface formation, wherein the first reactant and the second reactant produce an exothermic reaction that increases temperature and pressure in the subsurface formation to greater than a dew point of the condensate, wherein:
- increasing the temperature and pressure in the subsurface formation to greater than the dew point of the condensate vaporizes and thereby reduces condensate in the subsurface formation;
- and
- the exothermic reaction forms microfractures within the subsurface formation, thereby reducing condensate banking formation;
- and
- introducing a buffer solution with the first and second reactants into the subsurface formation, in which the buffer solution comprises at least one of monopotassium phosphate, N-cyclohexyl-2-aminoethanesulfonic acid, and borate.
