BREAKDOWN EXTRA Filtercake Breaker | Schlumberger


Enzyme and advanced chelant filtercake breaker

Improve filtercake removal efficiency in monovalent and divalent brines

The BREAKDOWN EXTRA enzyme and advanced chelant filtercake breaker uses the D-SOLVER EXTRA advanced brine-soluble chelating agent to destroy water-based filtercakes.

The agent is compatible with monovalent and divalent brines (except calcium bromide), and the corrosion rate is low as compared with acid or oxidizer treatments. The low-pH agent can complex many metal ions present in reservoir drill-in fluid (RDF) filtercakes and completion fluids, especially calcium and magnesium. 

The BREAKDOWN EXTRA breaker can be incorporated into a gravel pack carrier fluid if required during operations with Alternate Path gravel-pack shunt tube technology.
