fixing well potentials calculation after introducing the saturation table

Browse Source 
The calculation of well potentials of newly added well failed after using the saturation
table. Here, we fix it using much smaller parameters to stablize the
calculation, while it slows down the iteration process.

TODO: improves the convergence rate by either introducing better
paramters or better iteration strategy.
