As on the field, a well implementation is hugely expensive and a mistake could lead to huge economical losses. It's important to know the best dimensions and the most adapted to the problem before drilling.

We tested in this part three well dimensions. And we studied the behavior of the flow as a function of the well diameter that we have called D.

The solver used is a solver without anisotropy, moreover the permeability will be equal to $ K=7.10 {-7} \ m^2$.

__Velocity field D=0.2 m__

__Velocity field D=0.5 m__

__Velocicty field D=1 m__

We observe that an increasing in the well diameter leads to a decreasing of the maximum velocity magnitud.

__Pressure field D=0.2 m__

__Pressure field D= 0.5 m__

__Pressure field D= 1 m__

We observe that an increasing in the well diameter leads to a increasing of the maximum negative pressure.
