Abstract
The present disclosure relates to a method for stimulating a subterranean formation that includes performing an initial stimulation in a wellbore positioned within the subterranean formation to place a designed volume of a first proppant in fractures, determining a near wellbore fracture width of the fractures, determining an unpropped fracture length of the fractures based on a rock bending model, determining an unpropped fracture volume based on the unpropped fracture length and near wellbore width of the fractures and performing a second stimulation treatment to place a proppant in fractures in an amount equal to the unpropped fracture volume. This operation allows to restore the conductivity of fracture in the damaged zone.
