External Flint-Coat Casing Coating

Where to Use Flint-Coat?

• Surface Casing - for fresh water zone protection and stabilization of the bottom joints against unscrewing or breaking off during further drilling operations.
• Intermediate Casing - to stabilize bottom joints and for effective liner tie-backs as well as for protection across potential zones of fluid migration.
• Production Casing - for protection of immediate communication problems that could result in loss of production or invasion of bottom water into producing zone. Also for improved bonding during the later life of the well and during secondary or tertiary recovery operations.

Cement Failures Drain Off Profits:Flint-Coat Dramatically Reduces Cement Failures

Where does a cementing job fail? Field tests show the most common point of cementing failure is at the casing-to-cement interface, not at cement-to-formation. When your oil or gas escapes along the outside of the casing, only to drain off into the theif zone at another level, that's profits - your profits  -  lost ?up the drain?

The Problem: make wellbore and casing one.

The Solution: Flint-COAT, a proven process that produces a near-perfect bond between casing and cement, assures effective primary cementing, and reduces squeeze jobs to almost zero. There's more, too: You can perforate much closer to oil-water or gas-fluid contacts, without worry about communication between zones. The tight cement sheath protects your pipe from corrosion.

Flint-Coat: A coating of resin and jagged flint that produces a rugged surface, bonding cement to casing.

Millions of miniature reinforcing rods specially selected granite-like particles, are held permanently in resin adhesive. These particles turn ordinary cement into a reinforced concrete sheath that grips, holds and bonds to become a single unit with your casing. The bond of cement-to-casing becomes stronger than the tensile strength of the cement itself.
