Release kinetics of nano-Fe3O4 tracers from polymer-coated proppants in simulated reservoir environments

Key Points

• Release kinetics of nano-fe3O4 tracers significantly vary based on polymer coating.
• In one condition, up to 75% of tracers were released within 48 hours, emphasizing rapid dispersion.
• Assessment of release dynamics across multiple simulated reservoir environments provided valuable insights.
• Findings may indicate potential environmental impacts and necessitate further investigation into tracer fate.
