Abstract

Acid stimulation stands as a crucial technique for enhancing hydrocarbon production in carbonate reservoirs, yet its efficacy is often hindered by mineralogical complexities and formation damage. This paper explores a novel approach to optimize acid stimulation treatments in carbonate formations through the synergistic combination of chelating agents and seawater. Chelating agents, capable of forming stable complexes with metal ions, enhance acid penetration and dissolution while mitigating formation damage by preventing the precipitation of insoluble salts. Seawater, abundant in carbonate reservoir environments, serves as a cost-effective and environmentally friendly base fluid, offering inherent buffering capacity and compatibility with chelate complexes.
