Scale and Deposit Control

Flatirons Chemicals uses exclusive custom-blended scale and deposit control to prevent the buildup of scales and deposits caused by barium sulfate, calcium carbonate, calcium sulfate, iron carbonate, iron oxides, iron sulfide, and strontium sulfate.

FerroGuard is a member of the SI family of custom treatments, specially formulated by Flatirons Chemicals. The polymers that we use in FerroGuard are thermally stable, which makes it possible to handle higher temperatures, such as those found in the Bakken formation. In addition, they are designed to deliver stability in the occurrence of high concentrations of polyvalent cations, such as steric hindrance.

Several of the conventional phosphonates and acrylate-based polymers are vulnerable to precipitation from the tremendously high concentration of polyvalent cations in the produced water, such as calcium, iron, and strontium, which can weaken the performance. Furthermore, polymer dispersants are frequently fused into these formulations in order to even out or disperse the calcium phosphonate and calcium polyacrylates that may form.

Apply FerroGuard according to the produced water recovery rate, which includes the Fresh water feed rate. Applying fresh water down-hole inhibits the crystallization of salt on the nozzles and valves of the artificial lift by reducing the specific gravity to just under the point of saturation for sodium chloride.

Fresh water characteristically delivers supplementary alkalinity and a higher pH and encourages calcium carbonate precipitation, or calcium scale, to form when combined with produced water down-hole. Therefore, here at Flatirons Chemicals, we recommend feeding according to the combined produced water and fresh water flow, known as the total water recovery rate, when fresh water is applied.

FerroGuard is distinctively designed to deliver a synergistic blend of polymeric- based inhibitors that prevent both sulfate-based and carbonate-based hard water scales. The polymeric blend calms heavy metals such as iron that can otherwise poison mineral performance. FerroGuard continues to prove exceptional ongoing performance in harsh conditions that have led to the failure of traditional treatment programs.
