The Hydraulic Radius Concept, Slot Approximation, and Lamb’s Method give almost the same pressure gradients for various rheological models.Ģ. A user-friendly computer program was written to facilitate repeated analyses using any combination of rheological model and equivalent annular diameter definitions for the conventional drilling fluids for all ranges of inclination using the Rudi Rubiandini’s cuttings transport model.ġ. The impacts of rheological models and equivalent annular diameter definitions on annular pressure loss and ECD were examined for the conventional drilling fluids while aluminium oxide nanoparticles were used to examine the influence of nanofluids on the annular pressure gradient and ECD. ![]() They possess unique characteristics that differentiate them from microparticles, and make them adaptable to a wide range of applications. The nanoparticles are particles with an average diameter of less than 100nm. Nanofluids are specialized fluids obtained by careful combination of nanoparticles and a base fluid. This thesis examines hydraulics optimization using conventional drilling fluids and nano-based drilling fluids. A properly designed hydraulic system will help to improve drilling efficiency and lower drilling time and cost. Hydraulics optimization is an attempt to maximize the pressure drop across the bit by minimizing the parasitic pressure losses. The Hydraulics system shares common purposes with the drilling fluid, it helps to control subsurface pressures, remove cuttings from the well, clean the bit, size the pump, increase the rate of penetration, and minimize surge and swab pressures.
