Enhanced oil recovery (EOR) methods, such as chemical, thermal and microbial-EOR, need further development for brownfield reservoirs. Chemical enhanced oil recovery method can significantly improve the recovery factor of trapped oil from matured reservoirs. This is mainly achieved by lowering the interfacial tension (IFT) of the crude oil–brine systems and increasing the viscosity of the injected fluid. In this work, the use of nanoparticles in the form of Pickering emulsion and nanofluid have been explored to be a potential agents for EOR. Various studies involving the stability and rheology of nanoparticle based Pickering emulsion and nanofluid have been carried out followed by studies on the recovery efficiency of EOR process. The recovery efficiency of these nanoparticles-based systems has also been compared with the conventional polymer (P) and surfactant–polymer (SP) flood schemes. It has been observed that the use of nanoparticles for EOR can significantly improve the oil recovery. This presentation will provide details on the use of nanoparticles for enhanced oil recovery applications, their potential retention in the reservoirs, and other applications for subsurface oil and gas engineering.


Dr. Jitendra Sangwai is currently working as an Associate Professor in the Petroleum Engineering Program, Department of Ocean Engineering at Indian Institute of Technology (IITM) Madras, Chennai, India. He holds a M. Tech. and Ph. D. in Chemical Engineering from IIT Kharagpur and IIT Kanpur, respectively. He worked with Schlumberger for a brief period before moving to academics. His research interest lies mainly in the field of enhanced oil recovery, gas hydrates and nanotechnology applications for oil and gas engineering. He has published around 75 international journal papers.
