During the treatment process, the formations ( ) are selectively treated with a treatment fluid that is pumped into the interior of the adjacent screen assembly ( ). The valves ( ) of the respective screen assemblies ( ) progressively allow the treatment fluid to exit from the interior to the exterior of the screen assemblies ( ) such that each formation ( ) is progressively fractured.
