Halliburton's proprietary PowerSafe-D-Scale™ agent is an aqueous-based reactive fluid used to treat wells that have been drilled or circulated with a calcium or magnesium carbonate laden DIF. 

Applications include the following: 

• Dissolve DIF filter cake from the formation face and wellbore. 
• Dissolve polymer debris, filter cake, and calcium carbonate from screens. 
• Clean-up system after running screens to help eliminate damage associated with DIF. 
• Remove DIF debris and carbonate deposits from acid-sensitive alloy completions. 
• Treat damage resulting from loss of DIF to the formation.
