DESCRIPTION
Fracsal I crosslinking
additive consists of a specifically sized, sparingly-soluble borate
crosslinking agent suspended in a hydrocarbon based carrier
fluid. A standard concentration for Fracsal I is 1.0 gal per 1,000 gal
of fracturing fluid with crosslink times ranging from 2 to 3
minutes depending upon the pH, temperature, and type of
polymer-based fracturing fluid system. Fracsal I packaging can be
customized to meet specific requirements.
