We have tested over 2000 material coupons and almost 50 coatings to gain a comprehensive understanding of how dissolvable materials perform in the wellbore environment. We have used these learnings to optimize the design and materials of each ReacXion plug to ensure dissolution at the desired time. This has resulted in proprietary materials and coatings tailored for Bimodal dissolution (delayed) in low salinity and high salinity production environments.
