Case Study

Evaluation of Disodium Cocoamphodiacetate for Erosion-Corrosion Inhibition in Saline Water

Deyab, M. A. Journal of Molecular Liquids 271 (2018): 240-245.

The efficiency of the zwitterionic surfactant (ZS), disodium cocoamphodiacetate, was investigated for erosion-corrosion inhibition of API ×52 steel in sand containing saline produced water (SSPW) under different operating conditions using electrochemical and surface characterization techniques.
Methodology: Electrochemical measurements were done to determine the corrosion inhibition efficiency while surface analysis was carried out using SEM and AFM. Both static and dynamic conditions were used during the tests with different concentrations of the ZS and solution temperatures.
Key Findings:
· ZS displayed appreciable reduction in erosion-corrosion of API ×52 steel in SSPW, with inhibition efficiency of up to 93.2% and 66.7% under static and dynamic conditions respectively, and under all other operating conditions.
· ZS was found to be a mixed-type inhibitor based on polarization curves, suppressing anodic and cathodic reactions almost equally.
· The efficiency of the ZS was found to be dependent on the surfactant concentration and temperature with better results at optimized concentrations.
· The adsorption of the ZS on the metal surface to form a protective layer was confirmed with the SEM and AFM analysis that also improved the erosion-corrosion resistance.

Application of Disodium Cocoamphodiacetate in Graphene Oxide Nanofluid for Enhanced Oil Recovery

Liao, Kaili, et al. Journal of Petroleum Science and Engineering 213 (2022): 110372.

This case study explores the role of disodium cocoamphodiacetate (CAD), an amphoteric surfactant, in improving the dispersion stability and oil recovery performance of graphene oxide (GO) nanofluids. The study focuses on the potential application of CAD-enhanced nanofluids as effective agents for enhanced oil recovery (EOR).
Methods: A water-based graphene oxide nanofluid was formulated, and its stability and dispersibility were systematically evaluated under various conditions. Turbidity and conductivity measurements were used to assess the effects of ultrasonic dispersion time, GO concentration, and type of surfactant. The interfacial tension, emulsification capability, and displacement efficiency of the CAD/GO dispersion were further examined through micromodel and core flooding tests.
Key Results:
· The amphoteric surfactant CAD was identified as a highly suitable dispersing agent for GO. CAD significantly improved the dispersion stability of GO in aqueous solution.
· The CAD/GO dispersion reduced oil/water interfacial tension to as low as 10^-2 mN/m.
· The dispersion demonstrated excellent emulsifying properties and long-term emulsion stability.
· In core flooding tests, the CAD/GO nanofluid achieved an oil recovery rate of 11.8%, substantially higher than the 6.7% obtained using CAD aqueous solution alone.
· The improved performance is attributed to the enhanced interfacial activity and emulsification capacity provided by CAD.
