Abstract

Laboratory investigations and field applications have proved injection of polymer solution to be an effective means to improve oil recovery for reservoirs of medium oil viscosity The incremental oil produced in this case is the result of an increase in areal and vertical sweep efficiencies Biopolymers and synthetic polymers are the major categories used in the petroleum industry for specific reasons Biopolymers like xanthan are limited in their application as they are more susceptible to biodegradation Synthetic polymers like Hydrolyzed PolyAcrylaMide HPAM have a much wider application as they are less susceptible to biodegradation Furthermore development of nanotechnology has successfully provided technical and economical viable alternatives for present materials The objective of this study is to investigate the effect of combining clay nanoparticles with polymer solution on oil recovery This paper includes a history match of both onedimensional and twodimensional polymer floods using a threedimensional numerical model for fluid flow and mass transport Results indicated that the amount of polymer adsorption decreased when clay nanoparticles were added to the PolyAcrylaMide solution however mobility ratio improvement is believed to be the main contributor for the proposed method in order to enhance much oil recovery compared to xanthan flood and HPAM flood
