Concentrate solvent of mineral deposits “Para 2101” is designed to remove carbonate and sulfate deposits of calcium and magnesium in wells and oilfield equipment, in conditions of high salinity of produced water.
Mineral deposits solvent concentrate “Para” is a balanced composition of complexones in water-alcohol solution and/or organic and mineral acids.
The solvent concentrate of mineral deposits “Para2101” is produced in three grades – A, B, C in accordance with TU 2458 – 032 – 26913347 – 2016.
Used in services
Protection of process and pipeline equipment
Application
Continuous dosing or intermittent treatment at GZU, wells, at the inlet of oil treatment plants, preliminary discharge, pressure maintenance system.
Dosage
The optimal dosage is established according to the results of pilot tests at the facility.
To achieve the maximum economic effect of using a scale inhibitor, preliminary laboratory tests are recommended.
