For evaluating and analyzing the effect of temperature on the efficiency of the additives the most pilot test results are preferred and are reported by many companies. As an example, this using drag reducing FLO MXA (Baker Hughes B.V.) As the research results show, the expediency of its use to reduce the hydraulic resistance to flow high-viscosity oil at temperature conditions corresponding to the warm season.
(co)polymer of higher (meth)acrylate (polymers of higher alpha-olefins) with a hydrocarbon group having from 4 to 30 carbon atoms and a molecular weight of the polymer/copolymer not lower than 4-10(6).
