Formation damage from fines migration can occur during stimulation operations, particularly in sandstone. To prevent fines migration and clay swelling, various clay stabilization chemical treatments have been designed.
ClayBrake™ is a suite of clay control solutions that can help stabilize clay-sensitive formations and prevent fines migration. These ClayBrake solutions were designed for use in applications such as acidizing, gravel packing, and fracturing treatments, as well as in coiled-tubing operations. Further laboratory testing is recommended to determine which clay control product performs best with the fluid design and to determine the optimal loadings.
ClayBrake-1000 is OFS’s newest proprietary clay stabilizer used to combat both swelling and migrating clays. Depending on the quantity of clays present, it can be effective at loadings from 0.5gpt – 3gpt. Testing has shown superior performance to industry standard stabilizers such as choline chloride, cationic polymers, and even 2% KCl (depending on formation type).
Further laboratory testing is recommended to determine which clay control solution performs best with your fluid design and to determine the optimal loadings.
