A region of a borehole with one or more openings to be sealed off, such as
one or more fractures, voids, and or pores, may or may not be sealed off
around a tubular string with a borehole seal such as a packer or plug. A
carrying fluid may be utilized to transport a filtration material into
the opening to create a bridge, which at least partially seals the
opening, but still provides a flow path that permits fluid flow
therethrough. A solid material and/or settable material may then utilize
the fluid flow subsequently or be simultaneously spotted with or behind
the filtration material to thereby form compositions which effectively
seals off the flow path into the one or more openings.
