           Figure 11.11 Hydrocarbon gas WAG projects with various methods of agent delivery.


              Fig. 11.12 shows the results of the implemented WAG projects (using carbon
           dioxide) with different miscibility of gas and reservoir oil.
              The efficiency of the miscible WAG, as it is evident, is significantly higher than
           that of the immiscible one.
