Abstract: Methods, systems, and compositions for increasing hydrocarbon production from a wellbore where the wellbore or a nearby hydrocarbon reservoir is suffering from water blockage, one method including identifying water blockage in a rock sample of a formation via increased capillary pressure in the rock sample; formulating an exothermic reaction component to remove water blockage from a reservoir rock in situ via heat and pressure release, the reservoir rock type the same as the rock sample; injecting the exothermic reaction component into the wellbore; and allowing the exothermic reaction component to react to remove water blockage in situ to decrease capillary pressure of the reservoir rock without substantially changing porosity of the reservoir rock.

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.
