Crude oil producers have used pour point depressants with great success for several decades. However, chemical wax control packages can be plagued by crude oil specificity, large package treat rates, and waxy components that can be hard to apply.

This paper discusses what factors affect the performance of crude oil wax control additives and what contributes to crude oil specificity. This study investigated the effects of the wax control additives' polymer backbone, pendant chains, and molecular weight on cold flow performance. The impact of the solvents used, the extent of the packages' dilution and the effect of proper additive dosing is addressed.
