FRACSAL WATERBASE® HM
DESCRIPTION
Fracsal Waterbase HM is formulated as three separate products, Fracsal Waterbase HM1, Fracsal Waterbase HM2, and Fracsal Waterbase HM3, each product with a different crosslink time. The Fracsal Waterbase HM series consists of a specially sized, sparingly-soluble borate crosslinking agent suspended in an aqueous solution. Fracsal Waterbase HM series contains a supplemental additive as a scale inhibitor or iron control. Typical usage concentrations for all Fracsal Waterbase HM products is from 1 to 3 gal per 1,000 gal of fracturing fluid with crosslink times ranging from 1 minute to 3.5 minutes depending upon the pH, temperature, and type of polymer-based fracturing fluid system. Fracsal Waterbase HM packaging can be customized to meet specific requirements.
