Abstract
Drilling fluids are increasingly being infused with nanoparticles to improve their functionality. The potential of several nanoparticle types including metal oxides, carbon nanotubes, and graphene nanoplates to enhance the rheological, filtration, and thermal characteristics of drilling fluids is being researched. The literature uses nanoparticles at a concentration of roughly 3–5%. The mechanical, thermal, and physicochemical characteristics of drilling fluids can all be improved, heat transmission can be improved, and frictional resistance can be decreased with the help of nanoparticles. For drill-fluid rheology, silica and alumina nanoparticles are especially helpful. In general, research on the application of nanoparticles in drilling fluids is a potential field for the oil and gas sector.
