    In this research, the Compressive Strength (CS) and Thickening Time (TT) of oil well cement with different Metakaolin (MK) dosage was evaluated in the presence of Nanoclay (NC). The variables were randomized in a Box-Behnken Design (BBD) experiment using 5 - 15 wt. % MK by weight of cement and 5-15 wt. % NC by weight of MK. The CS and thickening time were assessed and optimized using Response Surface Methodology (RSM). The result shows that, CS increases linearly with NC and hyperbolically with MK. Cement slurries with 5–15 wt.% NC shorten TT by about 35 minutes in the presence of 5 wt.% MK. TT reduction of 103 minutes was recorded when MK was increased to 15 wt.% in the slurry with 5wt.% NC. At optimum condition, 10.78 wt. % MK and 13.73 wt. % NC resulted in CS and TT of 3029±2.65 psi and 410±1.25 minutes, respectively.
