dc.description.abstract	SAGD is a successful thermal recovery technique, applied in Permian super-viscous oil deposits in the Republic of Tatarstan. Despite its proven efficiency, SAGD remains an energy consuming technique and thus results in considerable GHG emissions. In one of the SAGD modifications a non-condensable gas is added to the injected steam to maintain pressure in the steam chamber. Methane is used as the main soluble non-condensable gas in oil reservoirs. Being lighter than steam, methane tends to accumulate in the upper part of steam chamber and reduce heat losses to the overburden rock. In addition, the ascending gas produces the gravity effect on oil, dragging it down towards the producer well. However, heat losses on the edges of the steam chamber (due to excess non-condensable gas) and risk of chamber collapse (due to reduced steam partial pressure) require careful estimation of the amounts of planned injected gas in accordance with the current size of the steam chamber. The numerical model was used to investigate the impact of different volumes of injected methane on SAGD process. Physical-chemical effects of the process including the methane diffusion and probability of asphaltenes precipitation should be considered in numerical models and require laboratory studies for a specific oil including oil displacement experiments by methane and steam. For that reason, steam and methane co-injection were conducted, analyzed and reproduced on one-dimensional physical model. Field scale numerical simulation results show the evidence that the modification of SAGD technology could become ineffective with continuous steam and methane co-injection or with cycling co-injection of steam and steam/methane with a ratio less than 2/1. Considering the technique limitations, numerical simulation allows to choose the best scenario (in terms of optimal volume and best well candidates) where methane, as an EOR agent in steam co-injection, shows better effectivity than as a fuel for water to steam conversion	ru_RU
