D-STROYER

Polymer-coated oxidizing breaker for water-based fluids

Improve the efficiency of water-based filtercake removal

D-STROYER polymer-coated oxidizing breaker aids in filtercake removal when used in water-based reservoir drill-in fluids (RDF) and completion fluids, and in lost-circulation pills during completion and workover operations.

The breaker is added at the surface to the reservoir drill in fluid system and deposited in the filtercake as an inert particle. During the completion and removal phase, a mild acidic solution slowly activates the D-STROYER breaker, increasing degradation rate of the filtercake. The breaker oxidizes polymers and other organic components such as xanthan and ester-based lubricants.
