Janus nanoparticles (JNPs) is a novel platform for use in upstream nanotechnology applications. Here, we report different synthesis routes of Janus nanoparticles, as well as their advanced surface functionalization and characterization. We discuss the platform’s relevancy to oil reservoir applications and demonstrate the utilization of JNPs as a solid co-emulsifier for enhanced oil recovery applications. JNPs are anisotropic nanoparticles, due to the functionalization of their surface with two different chemistries. The biphasic properties of JNPs enable this class to serve in many applications, such as food industry, pharmaceuticals, cosmetics, etc. Similarly, the oil and gas industry can also benefit from these useful properties of JNPs. Proposed functions of JNPs include delivering chemicals, and improve chemical compatibility. We first summarize useful and unique properties of JNPs, mostly arising from the anisotropic property prospective. Then we compare different methods to fabricate JNPs based on the surface functionalization degree. In addition, we review techniques to characterize properties of JNPs, such as droplet size and interfacial tension. Following the introduction of basic concepts and techniques of JNPs, we discuss specific applications of these novel structures in some areas of upstream operations, i.e., enhanced oil recovery and drilling fluids. More importantly, we identify challenges of economically engineering JNPs with desired properties for large-scale upstream applications, and propose possible solutions to some of these challenges.
