Oil reservoir production rates gradually decline as reservoir pressure lowers. There are many causes for this, including precipitation and asphaltene (ASP) deposition. This investigation seeks to assess the performance of Synthetic Zeolite-Zirconia-Cerium oxide (ZZC) nanocomposites (NCs) in the prevention of ASP damage using a coreflooding test under reservoir circumstances. In this research, used SEM, XRD, and EDX analyses to prevent ASP precipitation in the static phase and address ASP precipitation issues in the dynamic CO2 (CF) flooding test. Using Na-ZSM-5 zeolite nanoparticles (NPs), CO2-oil IFT experiments, isotherm models, and CO2 core flooding (CCF) tests at the static stage were carried out in the presence of ZZC. After that, CCF tests at the dynamic stage were created under the static conditions that had been established in order to examine permeability/porosity reduction in porous media. In comparison to Na-ZSM-5 zeolite NPs, ZZC absorbed more ASP. Additionally, ZZC and Na-ZSM-5 zeolite had decreased ASP precipitation when the pressure dropped from 2600 to 1700 Psi. The ASP depositions in the dynamic phase were reduced after adding ZZC, and the permeability/porosity reduction characteristics were enhanced. The results of this study may be used to address ASP precipitation during production phases.
