DD 955 (liquid) is a multi-charged liquid formation stabilizer for use with shale and clay reducing inhole swelling and instability problems.

Due to its ionic charges, DD 955 is absorbed directly into shales and clays, thereby preventing the water damage that causes loss of core and hole stability.

Once absorbed into the formation, the stabilizing effect imparted by DD 955 will remain resistant to any chemical changes in overall mud properties caused by varying geological and drilling conditions.

DD 955 effectiveness is enhanced when used with Torqueless.
