Its implementation in EOR improved oil recovery when compared with water flooding, surfactant and polymer flooding. EOR was conducted using OFITEĀ®'s reservoir permeability tester (RPT) as the core flooding apparatus on five set of Berea sandstone core samples. Its performance during enhanced oil recovery (EOR) was evaluated through core flooding, scanning electron microscopy (SEM), IFT and rheology. As a macromolecule, PSURFC combines dual oil recovery nature in a single component thereby influencing interfacial tension (IFT) and mobility ratio simultaneously. Rheology shows a shear-thinning behavior at room temperature indicates an improvement in the rheology on surfactant addition to the mixture. The inexpensive, non-toxic polymeric surfactant (PSURFC) is synthesized through free radical polymerization technique involving novel non-edible seed oil surfactant and xanthan gum. Abstract : This research focuses on heavy crude recovery using the dual recovery process of macromolecules formulated from environmentally friendly seed oil and polymer (Xanthan gum) with both hydrophobic and hydrophilic properties.
