• steam-assisted gravity drainage
• response surface methodology
• net present value
• central composite design

In this study, the application of response surface methodology and central composite design for modeling the influence of some operating variables on the performance of steam-assisted gravity drainage process for oil recovery was discussed. The maximized net present value of 105.16 $mm was obtained when the optimum conditions of steam-assisted gravity drainage operation process was designed following as injector/producer spacing of 5 m, injection pressure of 5,440 kPa, maximum steam injection rate of 725 m(3)/d, and spacing between two well pairs of 40 m. The predicted values match the experimental values reasonably well, with R2 of 0.967 and Q2 of 0.82 for net present value response.
