Alcohol ethoxylate-based nanosurfactant was experimentally assessed to be used in HCl acid-based stimulation recipes. The surface tension of the surfactant with different stimulation additives was compared with commonly-used linear and branched alcohol ethoxylate-based surfactants. Nanosurfactant showed the lowest CMC of 2 gpt compared to 3 and 5 gpt for branched and linear alcohol ethoxylate-based surfactants, respectively at 77°F. The Nanosurfactant illustrated the highest performance in lowering the surface tension of water to 17 dynes/cm at 280°F. Spent 20 wt% HCl acid and mutual solvent affected the performance of nanosurfactant by increasing the surface tension at temperatures up to 300°F. Live 20 wt% HCl acid showed insignificant effect on the performance of nanosurfactant. Despite the negative interactions with number of stimulation additives, nanosurfactant showed superior surface tension lowering abilities compared to linear and branched alcohol ethoxylate-based surfactants.
