Abstract
This invention relates to a method for achieving a seal by an expandable packing element having a generally tubular configuration and being fabricated from elastomeric material adapted to be utilized in conjunction with a packer apparatus within a well bore conduit during the completion or workover of a subterranean oil or gas well. Preferably the packing element is formed from a resilient elastomeric material such as ethylene propylene diene monomer adapted to withstand elevated temperatures and high pressures in subterranean wells. The tubular body member has an imperforate protective coating at least over its exterior surfaces, the coating being resistant to exposure to steam and hydrocarbons at elevated temperatures for extended periods for protection of the body member prior to its controlled expansion into well sealing relation, said coating becoming imperforate by said expansion.
