More than 100 gas wells started suffering from downhole halite (NaCl salt) deposition. Halite scale blocks part of production and reduces well capacity by 20-80% depending on well conditions. 


Water wash has been tried as mitigation methodology to treat the halite and to restore the well production and enhance the outflow. In addition, Halite Inhibitor was trialed but constraint on application method as the salt deposition mostly subsurface.    

Two Key points our company is interested in to receive proposed solutions: 

  1. Preventing methodology of halite forming down hole the well 
  2. Proven & cost-effective novel chemistry for halite inhibition, including practical application method.
