SC-21 Sticks are water-soluble sticks containing a blend of surfactants and non-ionic surfactants. This unique combination makes it very effective in higher hydrocarbon environments. SC-21 Sticks are primarily used to remove water from gas wells and increase gas production. The foaming action decreases the hydrostatic back-pressure which increases gas production that further enhances the foaming action until the well unloads.
SC-21 Sticks can be used to remove fluid from gas-condensate wells and flowing oil wells. For gas-condensate wells with more than 75% condensate, it is recommended to use the Select Industries Oil Foam Sticks in conjunction with SC-21 Sticks. SC-21 Sticks may also be used to increase the swabbing efficiency and life of swab cups. The slick coating along with the foaming action increases efficiency and life of swab cups and allows the well to flow easier. The perforations are often cleaned as a result of the surfactants and swabbing action.
The number of SC-21 Sticks to be used is based on the volume of fluid above the perforations. Field test indicate that the best results were achieved by using a larger initial slug treatment of 1/2 to 1 percent by weight of SC-21 Sticks to fluid above the perforations. A treatment of 1/2 to 1 percent by weight would require approximately 1.75 to 3.50 lbs of stick per BBL of fluid.

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.
