Drilling fluids are commonly used in oil and natural gas exploitation operations. In recent years, there has been a growing interest in the design of nanoparticles-based drilling fluids due to the great potential of nanoparticles for enhancing fluids performance. In particular, the effect of different types of nanoparticles on the functional properties of water-based drilling fluids (WBMs) has been studied, and an improvement of rheological, filtration, and thermal properties was reported. Bacterial nanocelluloses (BNCs) are nanofibers obtained from the fermentation of different substrates by various microorganisms. Their renewable nature and characteristics, including a high surface area to volume ratio, high strength, and stiffness, make them attractive for use in WBM design. In this work, the use of BNC as a novel polymeric additive for WBMs was studied. In addition, the drilling fluids with BNC were treated with enzymatic agents to evaluate their utilization in the cementing operation.
