ABSTRACT:
Methods for setting particulate plugs in at least partially horizontal sections of well bores are disclosed. In one embodiment, a method comprises the step of selecting a deposition location for a particulate plug within the at least partially horizontal section of the well bore. The method further comprises the step of providing a pumping conduit capable of delivering slurries to the deposition location. The method further comprises the step of pumping a first slurry through the pumping conduit to the deposition location such that a velocity of the first slurry in the well bore at the deposition location is less than or equal to the critical velocity of the first slurry in the well bore at the deposition location.
