FRACSAL MS
DESCRIPTION

Fracsal MS is a concentrated borate solution that is used to crosslink guar and derivatized guar-based fracture fluid systems. Fracsal MS is added continuously during the fracturing fluid pumping operation. Fracsal MS produces a unique gel structure downhole that is elastic and thermally stable. This product exhibits improved sand transport into fractures, and the ability to re-heal itself and form a stable gel structure after shearing.

FEATURES
  • Allows for a simple addition of product for batch or continuous mixed systems
  • No performance difference when used in sea water fracturing formulations
  • Performs in various aqueous-based polymer systems
  • Produce a fluid with superior leak-off control without addition of hydrocarbon and silica flour additives
  • Allows for precise control of desired pour points
  • Non-damaging to the resevoir
  • May be modified to meet customer requirements
