Abstract Chemical flooding is a crucial technique in petroleum recovery. Although synthetic polyacrylamides are widely used, they suffer from hard reservoir conditions (high salinity, temperature, and pressure) high costs. Current efforts focus on eco-friendly affordable biopolymers like xanthan gum to overcome these issues. This study screens modification improve its rheological properties tolerance shearing action by copolymerizing it with vinyl silane, monomers, silica nanoparticles. The new composite was characterized using Fourier Transform Infrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA), Atomic Force Microscopy (AFM), proton Nuclear Magnetic Resonance (NMR) tests. Its implementation evaluated polymer at 2200 psi pressure, 135,000 ppm 196°F temperature. Unlike previous studies that 176 degrees °F, 1800 psi, 30,000 ppm, without combining those three factors one experiment. of native were examined conditions, as well their viscoelastic (G‵ G‶). Flooding runs used actual Bahariya formation cores the lab scale. Simulation conducted lab/field scale tNavigator simulator economic feasibility calculate net present value. most outcoming findings this research comprise 1) investigating impact pressure xanthan. 2) exhibits more resistant criteria, recovered 27% residual oil versus 22% for 3) Modeling simulation exhibit 48% recovery 39% 37% water flooding. 4) Economically, through enhanced methods increased value $32mm $58mm traditional methods.

Reduction in viscosity at higher temperatures is the main limitation of utilizing cellulose ethers high thermal reservoir conditions for petroleum industry applications. In this study, ether (hydroxyethyl methyl (HEMC)) modified using organic carbonates, i.e., propylene carbonate (PC) and diethyl (DEC), to overcome reduced temperatures. The polymer composites were characterized through various analytical techniques, including Fourier-transform infrared (FTIR), H-NMR, X-ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetric analysis (TGA), differential calorimetry (DSC), ζ-potential measurement, molecular weight determination, rheology measurements. experimental results structural morphological characterization confirm modification formation a new carbonate-based ether. revealed that have greater stability, as samples demonstrated vaporization decomposition measurement indicates stability DEC- PC-modified composites. relative viscometry increased PC- DEC-containing polymers, up 93,000 99,000 g/moL, respectively. Moreover, exhibited levels shear strength resistance confirmed by determination. observed increase likely due enhanced inter- intramolecular interaction performed transesterification agent improves overall properties (HEMC) elevated concluded from study. approach study will open doors applications be beneficial substantial development industry.
