PLUG-SAL®

  • Water-soluble bridging agents
  • Added to saturated sodium chloride brine drilling fluids or pills to assure temporary bridging and sealing of lost circulation zones

DESCRIPTION

Plug-Sals are a series of specially sized and treated salt. The Plug-Sal products (Plug-Sal, Plug-Sal X, Plug-Sal XC) have a wide distribution of particle sizes suitable for bridging and sealing productive formations or sand control screens. Plug-Sals resist caking in the bag and disperse easily into brine systems. Plug-Sals are packaged in 50 lb or 25 kg sacks.
