  4. Abstract:
  5. A hydrogel nanocomposite was formulated and synthesized to control fine migration. The hydrogel was reinforced with titanium nanoparticles and its performance was studied. SEM and TEM images confirmed the formation of a homogeneous structure with uniform nanoparticle dispersion as fillers. Nanoparticles added to a hydrogel structure created a 3D structure with shear-thinning properties and a 92% increase in maximum elastic modulus. The hydrogel nanocomposite exhibited viscoelastic characteristics that endured temperature changes up to 200 °C and a delay in thermal degradation from 93 °C to 213 °C. Nanoparticles also reduced the sensitivity factor to salinity. Optimal flooding composition involves a pH of 5.4, a salinity of 10,000 ppm, and a 4.98% nanocomposite concentration. Waterflooding under these conditions reduces fine migration by 62%. The synthesized nanocomposite hydrogel can increase the contact angle of oil with rock by 77°, this remarkable property, coupled with its superior thermal stability, strong rheological strength, and low operational risk, positions this novel chemical as an outstanding solution for fine migration control in harsh reservoir environments without causing formation damage. So the hydrogel nanocomposite, by effectively preventing fine migration and production, safeguards reservoir integrity and extends its production lifespan, ensuring a sustainable approach to resource utilization and a reliable energy supply for future generations. © 2024 Elsevier B.V
