Drilling fluid property changes due to elevated temperature and aging time frequently cause problems in drilling deep wells. A laboratory investigation of the effect of high temperature (490) and long aging time (30 days) on water-base drilling fluid properties is made with Fann Model 70 HTHP Viscometer and Baroid Roller Oven. The results show a decrease in viscosity, yield point and gel strength with the increase in temperature. Shear stress for a particular temperature increases with the increase in shear rate, but shear stress at a given shear rate decreases with the increase in temperature. Viscosity, yield point and gel strength at a given temperature increase with aging time and aging effects are diminishing with the increase in aging time. Shear stress at a given shear rate increases with aging time and aging effects decrease with the increase in aging time. Finally, the value of the exponent of power law index n is calculated and found to be always less than unity.
