Flint-Coat is a high-temperature resin embedded with flint shards to create an extremely rough and hard surface for the OD of casing. It significantly enhances cement bond to casing as well as acting as a corrosion barrier. Flint-Coat is resistant to CO2, brine, and H2S, prevents gas migration, and provides cathodic protection.

Due to its hardiness, Flint-Coat can be used as production casing through unconsolidated zones, in corrosive environments, and as a coated tubing between injection intervals.

Communication and Loss

Communication and loss as a result of faulty tubing is preventable. By using Flint-Coat, you get reinforced, tough tubing that is durable enough to prevent and mitigate these problems.

Tough Enough for the Job

In the video above, Flint-Coat was installed in a rig. After being pulled out, despite some expected superficial marks, the Flint-Coat tubing requires no touch-ups or replacements.
