Competitive Adsorption‐Mediated Preservation of Effective Polymer Concentration in a Hydrophobically Associating Water‐Soluble Polymer/Sodium Dodecyl Sulfate Hybrid System for Mobility Control and Enhanced Heavy Oil Recovery
Conventional polymer flooding of medium‐to‐high‐viscosity heavy oil can be limited by near‐wellbore shear degradation and polymer retention, which impair injectivity and mobility control. Here, a hydrophobically associating water‐soluble polymer (HAWP)/sodium dodecyl sulfate (SDS) hybrid system was evaluated at 65°C...
