In drilling operations, drilling fluids are used to improve drilling operations and bring drilling cuttings to the surface. The formulation of these fluids, commonly known as drilling mud, is one of the most important factors of a successful drilling operation. Considering that the major part of the costs of drilling a well is related to the supply and pumping of drilling mud, the use of more efficient and better fluids plays an important role in reducing costs and increasing drilling efficiency. A suitable drilling fluid should have a high ability to cool the drill bit, bring the drilling cuttings to the surface, smooth the movement of the rotating drill pipes, control the wall pressure, transfer the hydraulic power of the pump to the drill bit and many other things. Preparation of drilling mud with the best formulation and effective materials is an important factor in increasing the speed of drilling, increasing the productivity of drilling operations, preventing the reduction of flow rate, reducing the cost of drilling a well, and finally increasing the success rate in post-drilling operations. In general, the purpose of using nano additives in drilling mud is to reduce the cost and prepare an optimal fluid by reducing the consumption of materials and improving its properties. Adding nanomaterials to the base fluid creates favorable rheological properties, very good stability of suspension and proper lubrication. The use of nanoparticles in drilling fluid enables petroleum industry engineers to quickly correct the properties of drilling fluid by changing the composition, size and distribution of nanoparticles. Also, in well cementing operations, by using advanced compounds, efficiency and productivity as well as operation costs can be greatly improved by using nanotechnology.
