Enhancement of rheological properties and cutting carrying capacity of water based drilling fluid using Al2O3 nanoparticles

Drilling mud is a necessary component of drilling operations. There have been notable attempts to enhance the filtration and rheological properties increase cutting carrying capacity water-based (WBM) using nanoparticles (NPs). This study investigates how varying Al2O3 concentrations affect fluids. In this study, different muds were produced bentonite (2.8g) without nanoparticle, 50% (1.4g) Al2O3(1.4) 0% bentonite(0g) 100% (2.8g). Testing comparisons done on formed samples' physiochemical properties, rheology, carry index (CCI). The Power Law Model was used define behavior manufactured samples, results showed that all samples pseudoplastic fluids remain preference for because their flow (n) less than 1. It observed addition directly proportional plastic viscosity, apparent viscosity yield point inversely gel strength fluid. also shows nanoparticle influences CCI as calculated gives high which means hole cleaning potential good. are feasible use in fluid formulation.
