Steam assisted gravity drainage (SAGD) is a promising technique for production of heavy oil reservoirs. Various new methods have been developed based on SAGD and one of them is SAGD-ISSLW. In this study, a comparison between SAGD and SAGD-ISSLW was investigated, and then effects of operational parameters and reservoir variables on SAGD-ISSLW performance were studied. The results show that cumulative oil production and oil production rate of SAGD-ISSLW process increase significantly in comparison to conventional SAGD. Higher injection rate and lower well spacing result in higher cumulative oil production in SAGD-ISSLW. Among reservoir variables, permeability has a considerable effect on oil production and other parameters have a negligible effect on the cumulative oil production, but affect steam chamber expansion.
