Abstract: Steam assisted gravity drainage is a widely used technique; however, the high operating costs and water usage associated with this technique necessitate a thorough investigation and optimisation of sensitive parameters. The focus of this study is to develop and optimise the steam assisted gravity drainage process for developing a new field. The traditional steam assisted gravity drainage process is simulated alongside a mature strategy for a period of 16 years. The mature strategy employed in this study includes pressure tapering and the injection of non-condensable gas. The simulation results demonstrate that the non-condensable gas injection strategy is more economically effective than the traditional steam assisted gravity drainage process in the mature stage. Additionally, parametric optimisation studies performed on operating pressure, injection temperature, and steam quality to maximise the net present value of the block; indicate an increase in net present value from 20 million dollars to 30 million dollars, highlighting the significance of this optimisation study.
