S & B pellets are very economical (as compared to conventional scale removal operations) and can eliminate or delay the need for HCL acid treatments. Continuous treatment with S & B pellets (especially after a conventional acid or clean-out job) can extend the time period between future scale removal operations. S & B pellets are less corrosive to steel pipe than conventional liquid HCL acid jobs because most of the acid generated by the pellets are released down hole. Conventional liquid HCL acid reacts with the steel, rust, and scale inside the pipe all the way down the well. S & B pellets are corrosion inhibited and mildly corrosive to steel (like inhibited amidosulfonic acids).
S & B pellets are safe to handle and easy to use by less experienced field personnel, however like all acids, contact with eyes or skin should be avoided and MSDS Sheets should be reviewed for additional safe handling measures before handling any such material. S & B pellets for short periods of time are safe to use in cement lined tubing and plastic lined tubing. Continued treatments over long periods of time through a by-pass feeder into cement lined pipe should be avoided.
