The aim of this research is to apply experimental design methodology for the optimization and sensitivity analysis of operating parameters on the steam-assisted gravity drainage process. These experiments, consisting of 26 cases, are determined by the D-optimal design. A response surface method was used to maximize net present value, which was obtained at 262.42 $mm for an optimal operation condition. The predicted values matched the experimental values reasonably well with R
