The friction reducer additives we choose to test were Torco MPZ, Slick 50, Revo and Dura lube. We will not go through each test separately step by step, we basically will just give you the final testing results. We made sure to do all the tests on the same day so the weather or temperature was the same for all the friction reducing additives.

 · Liquid friction reducers typically contain 20-30% active polymer loading, with the remaining volume being the carrier fluid to keep the polymer in suspension. By delivering powder, several benefits are gained including elimination of truck deliveries of FR liquids to location, reduction of total chemical volumes by 70-80%, reduction of ...
