ABSTRACT:
A technique includes running a string into a well bore and inhibiting formation face failure. The well bore extends at least partially through a non-producing layer and a hydrocarbon formation layer. The inhibiting of the formation face failure includes communicating a proppant into the well bore via the string until a well bore pressure exceeds a first formation stress of the non-producing layer, which causes a fracture to form in the non-producing layer, and communicating the proppant into the fracture to create a barrier layer.
