... this ranking procedure is not general for a variety of recovery processes, it is particularly suited to steam- assisted gravity drainage (SAGD) production. The ranking measure is highly correlated to performance parameters such as cumulative steam oil ratio (CSOR) and cumulative oil production rate (COPrate...

... steam oil ratio (CSOR) increased with the allowed liquid production rate. An increase in pay thickness resulted in increased oil production and a lower steam-oil ratio, but the net solvent to oil ratio was greater due to a reduction in solvent recovery. Water injection at an infill well increased...

.... It was proposed as a simple economic indicator, to be used instead of NPV, while determining the best SAGD operating conditions (1) . The simulation results showed that NPV had a linear relationship with RF and CDOR, but a decreasing exponential relationship with CSOR (Figure 1). In order to use STEP...

Overall, XSAGD accelerates bitumen recovery and lateral expansion of the steam chamber and reduces cumulative steam oil ratio (CSOR...
