Product Sheet: D-SOLVER EXTRA Advanced Brine-Soluble Chelating Agent

Date: 1/30/2017

The D-SOLVER EXTRA advanced brine-soluble chelating agent has low pH and can complex many metal ions present in reservoir drill-in fluid filtercakes and completion fluids—specifically calcium and magnesium.

It is used in the BREAKDOWN enzyme and chelant filtercake breaker system and the FAZEBREAK chelant-base filtercake system to assist in the cleanup of filtercakes deposited by water-base reservoir drill-in fluids and reversible invert emulsion reservoir drill-in systems. It is slow reacting and effective at lower temperatures.
