DESCRIPTION
Fracsal Ultra-FM is
formulated as three separate products, Fracsal Ultra-FM1, Fracsal Ultra-FM2 and Fracsal Ultra-FM3,
each product with a different crosslink time.
The Fracsal Ultra-FM series
consists of a specifically sized, sparingly-soluble borate
crosslinking agent suspended in an aqueous crosslink modifier
solution of solubilized salt, acid or alkali components which are
capable of adjusting the rate at which gelation of organic polymer
occurs, without substantially altering the final pH or other
characteristics of the crosslinked system. The standard
concentration for all Fracsal
Ultra-FM products is 1.2 gal per 1,000 gal of
fracturing fluid with crosslink times ranging from 30 seconds to
3.5 minutes depending upon the pH, temperature, and type of
polymer-based fracturing fluid system. Fracsal Ultra-FM packaging can be
customized to meet specific requirements.
