FS-1259 Sticks are designed to be used for wells making 5-10 barrels of water (0-200,000 PPM Chlorides) per day and up to 75% hydrocarbon content. For gas-condensate wells with more than 75% condensate, it is recommended to use Select Oil Foam Sticks. FS-1259 Sticks have been used in water injection wells in combination with ACID STICKS® to help reduce injection pressures. Surfactants contained in FS-1259 Sticks can help remove oil coatings on scale. This helps the ACID STICKS® to react with the exposed scale.
