This task allowed us to have a good learning of ECLIPSE by simulating some simple cases. We could familiarise ourselves with ECLIPSE by writing a data input file. In this cases it is not difficult to write this file but when the geometry is difficult a program GRID program must be used to generate a good mesh.

Moreover, the aim of this task was very interesting because it was a real engineer problem. It showed us what could be asked to an engineer in order to increase oil product from well.

Fortunately in this kind of simulation the physique proprieties must have the real values, because so else the results can be non physique (example pressure in the reservoir).
