Summary: | 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. |
