| 16. A method of stabilizing an unconsolidated subterranean formation that is penetrated by a well bore comprising:
providing a consolidating agent capable of consolidating the unconsolidated subterranean formation;
introducing the consolidating agent into a portion of the unconsolidated subterranean formation-surrounding the well bore
so as to form a consolidated region;
providing an after-flush fluid;
introducing the after-flush fluid into the portion of the subterranean formation after introduction of the consolidating agent
and while the consolidating agent is in a flowable state;
introducing a relative permeability modifier fluid into the unconsolidated subterranean formation after introduction of the
after-fluid fluid so as to penetrate through the portion of the unconsolidated subterranean formation; and
allowing the consolidating agent to set.
