Scale Inhibitor Para 2151

Scale inhibitor “PARA 2151” is designed for complex protection of oilfield equipment from calcium sulfate and calcium carbonate deposits in conditions of high salinity of produced waters.

Scale inhibitor PARA 2151 is designed to effectively prevent the precipitation of salts of various chemical composition at all stages of oil production, transportation and treatment; protection of wells, deep and surface oilfield equipment in conditions of high salinity of produced waters.

Scale inhibitor PARA 2151 is a balanced composition based on phosphonic acid derivatives in water and/or alcohols, produced in three grades A1, A2, A3 depending on the area and conditions of use in accordance with TU 2458-035-26913347-2016.

Used in services

Protection of equipment of water circulation systems

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 based on the results of pilot tests at the facility.

To achieve the maximum economic effect of using a scale inhibitor, it is recommended to conduct preliminary laboratory tests.
