Hydrocarbon recovery procedures have advanced tremendously thanks to the rise in global energy consumption as well as the rising need for fossil fuels as primary energy supplies. Nanoparticles are one example of a novel class of materials that has been the subject of extensive research as a means to simplify and reduce the cost of oil exploration & production under extreme reservoir conditions. Nanomaterials' distinct physical and chemical properties have made them useful in a wide variety of gas and oil operations, including discovery, drilling, cementing, production & stimulation, Enhanced Oil Recovery (EOR), reservoir characterization, refinement, and processing. In this post, we will cover the latest advancements in nanomaterials and their involvement in new or improved applications in the oil and gas industry. Nanomaterials including metal oxide and metal nanoparticles, CNTs, and magnetic nanoparticles are widely employed in the oil and gas industry, and their synthesis and functionalization are summarized here. In addition, their uses in various oil and gas procedures are highlighted. Finally, some potential future uses and a look ahead to the current difficulties are discussed.
