Inflatable bridge plug

A well plugging technique that includes a downhole plug system to be disposed downhole in a well and including a plug bladder system including an inflatable bladder (to be inflated with a resin) and a check valve (to facilitate flow of the resin into, and inhibit back flow of the resin out of, the bladder), and a plug deployment system including a resin chamber to house the resin and a resin deployment system to urge the resin to flow from the resin chamber, through the check valve and into the inflatable bladder while the downhole plug system is disposed downhole in the well, to inflate the plug bladder system into sealing contact with a surrounding downhole portion of the well. The resin including a hardening resin adapted to harden inside of the inflatable bladder to form a hardened plug downhole in the well.
