Effects of sugarcane and polyanionic cellulose on rheological properties of drilling mud: An experimental approach

摘要

Invasion of fluids into porous media during drilling can lead to irreparable damage and reduced well productivity. Minimizing formation damage, enhancing well productivity and saving cost will thus depend on the introduction of less invasive fluid formulations. In this study four different mud formulations were prepared to investigate the effect of bagasse on rheological properties of the bentonite-based mud. These fluid properties were determined according to API standard. Statistical analyses showed that adding bagasse could successfully enhance the rheological behavior of the bentonite-based mud. Moreover, the formulation containing sugarcane increased viscosity up to almost two times. Gel strength and viscosity also increased overtime.
