The general objective of this work is to evaluate the application of hybrid silica-lignin nanoparticles as viscosifier or filtration reducer additives in drilling fluids. It seeks to design fluids that emulate those used in drilling operations, especially in water-based formulations, whose use has grown in recent years due to the economic and environmental advantages they present compared to oil-based muds. This will allow delving into the possible technological variants that can be incorporated to replace high-cost components, currently imported in Argentina. Silica nanoparticles functionalized with sulfonated lignin are proposed as additives, and their effect on the main functional properties of fluids is compared to that of simple silica nanoparticles.
