A first reservoir flow simulation experiment

Figure 2 shows the transmissibility of a first simple reservoir model. The transmissibility is increased in an elliptic area in the center. Such high transmissibility region may be caused by sand deposits within a paleochannel.

I chose to drill two wells into the reservoir: each well is located within the high transmissibility area. One of the wells adds fluids (source), the other one extracts fluids (sink). The snapshots in Figure 3 show the areas of increased pressure or fluid density.

The simulation includes two wells: The northern well adds fluid to the subsurface increasing the pressure around the well, the southern well extracts fluid and lowers the local pressure. I arbitrarily positioned the two wells at the foci of the reservoir's elliptic high transmissibility region.
