Impact of Acrylic Acid on ASP Flooding Performance: Interfacial Tension Behaviour
Shuaib Ahmed Kalwar, Khaled Abdalla Elraies and Shehzad Ahmed

Abstract:
In chemical EOR, interfacial tension plays one of the important roles in carbonate reservoirs. Carbonate reservoirs are composed of calcium and magnesium minerals which affect the performance of alkali and surfactants to reduce interfacial tension. In this study, acrylic acid was used to inhibit precipitation and to create a compatible solution without any precipitations. The impact of acrylic acid on interfacial tension was investigated using various inhibitor concentrations with a hard brine composition of 59, 940 TDS. Sodium metaborate, alpha olefin sulfonate and internal olefin sulfonate were screened as promising chemicals for interfacial tension. Various fluid-fluid compatibility tests were first performed to find the optimum acid-alkali ratio to prevent any precipitations. The optimum acid-alkali ratio was found to be 0.6:1.0. This ratio was then used to keep all solution without any precipitations for 30 days at 80°C. It was also observed that the increase in acid-alkali concentrations can significantly reduce the interfacial tension. Using the optimum concentration for acid, alkali and surfactant, the interfacial tension reduced from 14.9-0.401 mN m-1.
