Innovative Chemical Offers Enhanced Performance in Both Paraffin Control and Corrosion Inhibition in Duvernay Production

Abstract The Duvernay formation, a prominent shale formation spanning central Alberta, is an unconventional, liquids-rich reservoir providing access to Canadian condensate and natural gas liquids. As with other shale plays, production from the Duvernay formation presents numerous operational challenges, notably paraffin deposition and corrosion, which are both technically and economically demanding. Addressing these challenges with economic efficiency in mind, we initiated the development of a novel chemistry capable of both treating paraffin and preventing corrosion. This paper discusses the comprehensive research, including test procedures and results, which led to the creation of this innovative chemistry. The development process culminated in a new, patent-pending chemical solution that offers enhanced performance in both paraffin control and corrosion inhibition. This dual-purpose solution allows industry producers to reduce the operational footprint and costs associated with applying separate chemistries. By integrating these functionalities, the novel chemistry enhances performance in an industry where cost efficiency is crucial.
