Once drilling commences, automated drill-off tests vary the WOB and RPM systematically while measuring ROP and MSE. Plotting these variables isolates the optimal "sweet spot" for performance before the bit founders (reaches a point where increasing WOB no longer increases ROP). 4.

Response Surface Methodology has emerged as a valuable statistical tool for drilling optimization. RSM analyzes the effects of independent drilling mechanical parameters—WOB, RPM, flow rate, and torque—on response variables such as ROP and MSE with high statistical confidence levels. This approach enables engineers to identify optimal operating conditions through systematic experimental design and regression analysis. Plotting these variables isolates the optimal "sweet spot"
