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.
