Opportunities and challenges of nanotechnology in enhanced oil recovery: An overview

Abstract

Primary objective of this review includes advantages and challenges associated with implementation of nanotechnology in EOR (enhanced oil recovery). Nanotechnology refers to science which deals in dimensions of nanoscale (1–100 nm). Nanotechnology is an important technique due to their small size. Small size of particles offers high surface area which makes nanotechnology as one of the candidates for EOR technique. Also, nanoparticles result in change in fluid and formation properties which ultimately leads to increased production. Wettability alteration, increase in structural disjoint pressure and reduction in interfacial tension are some of the factors that are being contributed by Nanoparticles for enhanced oil recovery. Apart from these advantages there are some drawbacks associated with the techniques. Mass scale production of Nanoparticles, stability of Nanoparticles is some of the tedious and unresolved task that require immediate attention. Thus, the review focusses on advantages and challenges discussed in brief occurring in implementation of nanotechnology in EOR.
