Oscar Gonzalez, GeolOil LLC President portrait

" A great petrophysics software must excel in four aspects:
1.- Designed after decades of petrophysics consulting.
2.- Modern programming practices in compiler design and threads.
3.- Advanced & innovative applied mathematical algorithms.
4.- An outstanding and fast customer service.
Well, we have all these traits."    Oscar Gonzalez. GeolOil LLC, Director ∎
