1. A method for reducing fluid loss in downhole operations, the method comprising:
introducing a hydrated flocculated polymer downhole into a fluid loss flow path in a subterranean formation, wherein the hydrated flocculated polymer is produced from a hydratable polymer, wherein the hydrated flocculated polymer is produced by:
providing an invert emulsion of an oil phase and a water phase, with the water phase containing the hydratable polymer; and
shearing the invert emulsion so as to produce the hydrated flocculated polymer; and
allowing the hydrated flocculated polymer to accumulate at a pore throat to reduce fluid loss.
