Water Glass Coating as Protective Barrier for Swellable Packers

Use of water glass as dissolvable barrier for protection against premature swelling of swellable packers.

Water glass is a reliably dissolvable material at elevated temperature in water based fluids.  Swellable packers are expected to reach setting location without deploying (changing minimally in outer dimension).  Applying a water glass coating could allow for a reliable barrier to unwanted deployment until conditions to remove the coating are supplied (fluid and temperature).

Examples of waterglass compositions are sodium silicate and potassium silicate.
