DESCRIPTION
Inhibisal Ultra SI
additives are anionic, scale inhibitor concentrates formulated with
either the ammonium or sodium salt of a hydroxy amino phosphonic
acid. The Inhibisal Ultra
SI products (Inhibisal
Ultra SI-138, Inhibisal Ultra SI-139, Inhibisal
Ultra SI-141) are utilized in the control of
calcium carbonate and barium/strontium sulfate scales in produced
formation waters, water-based fracturing fluids, or brines utilized
as kill fluids at temperatures up to 148.9°C (300°F). Inhibisal Ultra SI chemicals
are typically added to production water at concentrations ranging
from 15 to 25 ppm based on continuous surface volume of produced
water, or down hole by continuous injection through capillary
tubing or annular injection. When used in a fracturing fluid
or as a brine kill fluid additive, the concentration ranges from
0.2 to 0.3 gal/1,000 gal (0.2 to 0.3 L/m3).
Inhibisal Ultra SI
packaging can be customized to meet specific requirements.
