This paper provides an extensive analysis to the current state of research on the use of Nano technology in order to improve the cement compressive strength for the well cementing applications in the oil and gas industry. By altering the microstructure and enhancing interfacial bonding between cement particles, nanoparticles have been found to enhance the cement mechanical properties. Various nanomaterials (NM), including graphene oxide, Nano-Silica, Nano-Alumina & Nano-Iron oxide, have been studied for their ability to enhance cement compressive strength.

Furthermore, this review examines the factors that influence the effectiveness of the nanomaterial in oil and gas well cementing, including size, shape, surface area, and dosage. Moreover, the effect of various sizes of the nanomaterials plays an important role in determining the enhancement extend of the cement compressive strength. This review focuses on the impact of different sizes of the nanoparticles on the cement properties including the cement compressive strength. The findings from this review can help to provide insights into the optimal size of the nanoparticles required for effective cementing job in the oil and gas wells.
