It is worth mentioning that this case exhibits strong interferences between fractures during
production. Even in this context, we see that our solution remains very robust.

versus reference solution (thick red line).

versus reference solution (thick red line).
Figure 14 displays the cumulative relative production error with and without transmissibility
corrections. The solution obtained without transmissibility corrections leads as before to an
increasing error with time, reaching 3 percent after 10 years of production. The proposed
solution leads to a bounded error which is in this case is lower than 0.5 percent in terms of
cumulative production.
