Summary: By synergizing the composition of injection water through SmartWater technology, enhanced oil recovery (EOR) methods can be optimized to achieve higher oil recoveries and reduce the volume requirements of chemicals and gas. This study demonstrates the significant benefits of different SmartWater-based synergistic EOR technologies, which can have practical implications for more efficient and economical EOR projects in the field.

Summary: The study investigates the application of nanoparticles in stabilizing foam in fractured tight carbonate rocks. Negatively charged nanoparticles show better ability in stabilizing the foam than positively charged ones. Graphene quantum dots exhibit better stability due to their structure and exceptional chemical stability. The study also highlights the impact of rock-fracture permeability contrast on foam performance.

Summary: Continuous oil spills not only harm air and water quality, but also cause significant damage to shallow and deep-water ecosystems. Current methods for oil sorption are not reusable, selective, or easily mass-produced. Therefore, there is a pressing need for an economical, scalable, and efficient oil sorbent material.

Summary: Traditionally, soil decontamination or enhanced oil recovery procedures involve injecting surfactants and polymers separately to avoid aggregation. Recent studies suggest that in some cases, using interacting polymer and surfactant systems can be more effective for oil recovery, contrary to previous beliefs.

Summary: Increasing demand for chemical additives in the petroleum industry has prompted the need to develop environmentally-friendly alternatives. In this study, a novel biocompatible surfactant was synthesized and its application in surfactant-stabilized foam was analyzed. The surfactant showed comparable results to commonly used surfactants in chemical enhanced oil recovery. The experimental procedure included surfactant synthesis and feasibility study of its implementation. The results suggest that the surfactant has potential for application in laboratory and field studies, increasing oil yield.

Summary: The study compared the EOR performance of Gum Arabic (GA) and Xanthan Gum (XG) solutions, showing similar oil recovery for 1.0 wt% GA and 0.1 wt% XG polymeric solutions. GA exhibited Newtonian viscosity at high shear rates. The impact of nano-polymeric solutions on oil recovery was found to be higher than that of polymeric solutions.

Summary: This research investigates the combination of nanoparticles (Al2O3) and surface-active ionic liquid (C12py)Cl for enhanced oil recovery. The addition of nanoparticles and stabilizer PVP increases the viscosity and reduces the interfacial tension of the foam system. The nanofluid formulation shows potential for application in brine and can alter the wettability of carbonate rocks.

Summary: Polymer-enhanced foam (AOS-DYG) flooding was adopted as an enhanced oil recovery (EOR) technology for the Bohai oilfield to improve foam stability. The addition of polymer increased the thickening ability, liquid film thickness, and gas-liquid interface adsorption layer strength, significantly improving foam stability. Core displacement test results confirmed the excellent mobility control ability of AOS-DYG foam in porous media.
