                    Figure 4.5 Liquid dropout curve of the methane-n-butane mixture.

              The condensate recovery was calculated by Eq. 2.12, as shown in Fig. 4.7.It
              shows that the 25% of condensate was recovered after 5 cycles of huff-n-puff
              methane injection. A numerical simulation model was able to match the
              experimental data by tuning relative permeabilities.
