1. A method for using an exothermic drilling fluid composition during drilling operations, the method comprising:
evaluating a current state of a drill pipe during a drilling operation within a subterranean formation;
following an indication of sticking of the drill pipe during a drilling operation due to drill cuttings, injecting a first drilling fluid composition comprising an initial quantity of a first exothermic reactant and bentonite into the subterranean formation;
following injecting of the first drilling fluid composition comprising the first exothermic reactant, injecting a second drilling fluid composition comprising an initial quantity of a second exothermic reactant that is different from the first exothermic reactant and bentonite into the subterranean formation,
wherein the first and second drilling fluid compositions comprising the first and second exothermic reactants, respectively, are injected separately;
allowing an exothermic reaction to occur between the first exothermic reactant and the second exothermic reactant within the subterranean formation,
wherein the exothermic reaction produces gas and water such that interfacial tension between the drilling fluid composition and the gas causes an increased lifting effect for the drill cuttings, thereby reducing friction on the drill pipe; and
evaluating a new state of the drill pipe during the drilling operation.
