    pH-responsive phenol–formaldehyde resin: aggregation mechanism and plugging science

    Enhanced oil recovery research focuses on the phenol–formaldehyde resin (PFR) solution (EOR). We studied PFR’s morphology and aggregation kinetics at various pH levels. A hydrated layer formed on the surface o...

    Molecular modeling of phenol formaldehyde resin—surfactant and its dispersion stability in salt solution

    The stability of phenol–formaldehyde resin (nHAP) in the oil displacement process influences its flooding and profile control capabilities. There aren't many studies that compare how various surfactants affect...

    Aggregation kinetics and morphological changes of PFR and establishment of triple-layer surface complexation model to explain ion difference

    The anions in the phenol–formaldehyde resin colloid interact with the metal cations in the system to form aggregates with different fractal structures. In this study, Mg2+ and Na+ were studied. At low cationic co...
