Abstract Drill cuttings are broken bits of solid material removed from a borehole drilled by rotary, percussion, or auger
methods and brought to the surface in the drilling mud. When these cuttings enter the annulus, they have an
effect on the drilling fluid rheology and density, which is, in general, quite difficult to evaluate. By introducing
an empirical correlation for the rheological properties of cuttings-laden drilling fluids, this study proposes a pressure-loss prediction method for an extended-reach well (ERW). After verifying the accuracy of this method, a case
study is considered and a sensitivity analysis is conducted assuming a yield-power law… More >
