SAPP Sticks (Sodium Acid Pyrophosphate) are condensate-dispersible, water soluble sticks containing a combination of surfactants, blended with a sodium acid pyrophosphate. SAPP Sticks will perform in the presence of salt or in fresh water systems.


SAPP Sticks are primarily designed as a mud thinner/dispersant. However, other advantages that have been realized from the use of SAPP Sticks include decreased wear on shaker screen due to thinner mud, friction reducer, the prevention of the formation of “mud rings,” the prevention of bit balling, calcium inhibition, and pH reduction.


The number of SAPP Sticks to be used varies from one drilling operation to another. The weight of mud, drilling depth and water weight can affect the number of sticks to be dropped. Field tests indicate that the best results are achieved under normal drilling operations when 1 to 2 (1 1/4″ x 15″) sticks were dropped to each joint of drill stem added.

Safety and Handling

Please review SDS prior to using this product. As with all industrial chemicals, contact with eyes or skin should be avoided. Wash thoroughly with water if contact with skin is made. Sticks should be stored in a cool dry place. Always remove stick from plastic bag or cardboard tube before using. Bag or tube can be used as a glove to avoid contact with hands.
