Claystop is an effective clay stabilizer used in drilling operations within clay-rich formations. Claystop penetrates clay pores and helps bind them together, thereby preventing the water in the drilling mud from entering the pores and eliminating formation swelling.

Claystop is a concentrated liquid polymer with dispersing (thinning) properties that exceptionally removes mud and clay deposits (sedimentation) from gravel-packed zones and production formations.

Claystop also functions as an efficient mud thinner.
