... Abstract Thermal rheological properties of three drilling fluids suggested for hot environments were experimentally investigated using both HTHP dynamic rheometer and classical viscometer. Two of them were polymer based muds commercially used in geothermal drilling, and the third one...

... Abstract The effects of wall slip on the reliability of viscosity data obtained using concentric-cylinder viscometers was investigated for water-based Bentonite drilling muds. Viscosity data for a typical mud system (solid content = 8%) were found to depend on the gap width demonstrating...
