Acquacoltura e Pesca Pubblicazione scientifica Surfactant-Polymer Flooding Schemes (A Comparative Analysis) FILONE TECNOLOGICO TEMA trasformazione e commercializzazione RIASSUNTO AbstractSurfactant Polymer (SP) flooding-a chemical EOR method, involves the injection of surfactants into the reservoir to reduce interfacial tension between oil and water and thus reduce capillary pressure for easy mobilization of oil. Polymers are also injected alongside to reduce mobility ratio and gather the oil droplet within the reservoir to create an oil bank and mobilize the oil towards the wellbore.In this paper, three different methods or mechanisms of implementing surfactant Polymer flooding were considered. Firstly, for Scheme or Method A, after water flooding, Sodium Dodecyl sulphate slug was injected then followed by gum Arabic slug. For Scheme B, a slug consisting of a mixture of Sodium Dodecyl sulphate and gum Arabic was injected after water flooding. In Scheme C, the core was first soaked with Sodium Dodecyl sulphate and then flooded with gum Arabic.The result showed a recovery of 56.25% of the water flooding residual oil for the first method while the other two Methods yielded displacement efficiencies of 66.12% and 64.4% respectively.In summary, the Mechanisms of implementing an SP flooding have some effects on the Oil recovery and as such care must be taken in selecting the mechanism to be adopted so as to optimize recovery.
