FS-16 SAPP STICKS are a water soluble and condensate dispersible stick that contains a blend of our FS-16 BIT STICK surfactants with sodium acid pyrophosphate, and can be used in salt or fresh water applications.
The amount of FS-16 SAPP STICKS used per application will vary from one well to another. Water weight, mud weight, depth, and other variables come into play. Tests indicate that 1 to 2 1-¼” x 15” FS-16 SAPP STICKS per joint of drill stem added will be a good starting point. You can add or subtract the amount of sticks used once you have received your initial result so that you can receive the best benefit for your application.
Remember to drop the amount of sticks you have decided on each time an additional joint of drill pipe is added to the drill string. The components in the stick will dissolve as fluid moves down hole. Also remember to remove each stick from its cardboard tube prior to dropping.
