SAGD PERFORMANCE IMPROVEMENT IN RESERVOIRS WITH HIGH SOLUTION GAS-OIL RATIO
Paper addresses the issue of Steam Assisted Gravity Drainage (SAGD) performance in the reservoirs with various solution gas-oil ratios (GOR). Results of extensive reservoir simulation study show that during the steam injection gas comes out of solution and accumulates at the edge of the steam chamber. In cases of high methane content in the bitumen the effect of gas layer development ahead of the steam front becomes detrimental and reduces the efficiency of conventional SAGD performance. It was suggested that by adjusting injected fluid composition it is possible to mitigate negative impact of the reduced heat transfer from water steam to bitumen.
