Wet Drilled Cuttings Bed Rheology

The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning often a bottleneck well construction. studies so far have targeted the fluid cuttings’ capability through experiments, simulations or field data. Observed differences due to changes properties and compositions reported but not always fully understood. In this study, bed, wetted with single fluid, was evaluated. experiments were performed parallel plates Anton Paar Physica 301 rheometer. results showed systematic internal friction behaviors between tests beds oil-based water-based fluids. observations indicated that cutting polymeric released clusters particles when external forces overcame bonding started break up. Similarly, it observed bed allowed free as particles. These findings may explain previous studies.
