Atren D-EM is a demulsifier intended to prevent formation of inverted emulsions in well stimulation processes. It can be used as part of fluids for acidizing of bottom holes of carbonate and terrigenous reservoirs, as well as for hydraulic fracturing.
Atren D-EM is injected into the well as part of fluids for reservoir acidizing (or fluids for hydraulic fracturing), and does not require additional preparation.
Atren D-EM can be used in a wide range of temperatures.
The content of the demulsifier Atren D-EM in the finished composition may vary from 0.2 to 0.5 %.
