Increasing drilling mud productivity with the help of nano materials and investigating the effect of this mixture on the rate of increased oil recovery (Case study: Asmari oil field located in Iran)

Today, various nano materials are used in the process of increasing the yield, including polyacrylamide-based nano composite gels. These materials, which are formed by copolymerization of their own monomer with crosslinking agents, are capable of absorbing significant amounts of water. By using different co-monomers or changing the network structure, networks with desired properties can be produced. Hydrogels made with different amounts of clay nanoparticles in two solutions of salt water and pure water were subjected to swelling tests, which yielded significant results. These results showed that in the absorption of pure water and consequently more water absorption from reservoirs, the nano composite hydrogel containing ۰.۲% clay had the highest absorption and had ۱۸۰% more absorption capacity than the hydrogel without clay nanoparticles. These results were also true for salt water, with the difference that the equilibrium time for water absorption increased. Also, to study the effect of using nanoparticles and hydrogels on drilling mud, viscosity was studied. The results indicated an increase in the post-reduction viscosity of hydrogels containing nano composite materials compared to conventional hydrogels.
