Universal defoamer for water-based drilling fluids DEM VP-1. Silicone-free, mineral-based with polyglycols. High efficiency of defoaming at low working concentrations in all types of water-based drilling fluids.
Used in the construction of oil and gas wells as an additive in drilling and grouting solutions in concentrations:
- clay drilling fluids from 0.1 to 5 kg per 1 m3 of solution.
- biopolymer drilling fluids from 0.1 to 3 kg per 1 m3 solution.
The defoamer can be injected into the foaming medium in portions or continuously in an accurate dosage. Loading by weight varies depending on the type of drilling fluid, the properties of the foaming medium, the trajectory of the wellbore. For selection of effective dosage it is recommended to carry out laboratory tests.
Mix well before use.
