We investigate a new model for fluid flows in diatomite formations recently
introduced by Barenblatt, Patzek, Prostokishin and Silin. We provide numerical
evidences of the existence of a sharp front between the damaged and the undamaged
rock, and we study the structure of this front. Finally, we simulate some infield
operations and we set up a qualitative model control problem to maximize the profit
during the oil extraction.
