New mud for drilling in clay and shale rocks with cationic KAN-001 polymer

This paper presents laboratory researches on KAN-001 cationic polymer application dedicated for drilling fluids used in drilling through sensitive shale formation and also the formulation of a new mud system for drilling in clayish rocks. Laboratory researches showed the great utility of KAN-001 polymer, synthesized in AGH-UST, for its application in special drilling fluids for shale and clay rocks. A new mud system – Mud-17 – with an addition of KAN-001 polymer, is distinguished by good technological parameters. It is resistant against univalent and divalent salts contamination. Therefore, a new mud system can be salted up to the saturation. Mud-17 is also resistant against high temperature, so it can be used in deep wells.
