Galactasol™ carboxymethyl hydroxypropyl guar

Galactasol carboxymethyl hydroxypropyl guar (CMHPG) is an anionic guar derivative used as a gelling agent for oil and gas hydraulic fracturing fluids to suspend proppant. Galactasol CMHPG is easily soluble in cold temperature environments. Furthermore, Galactasol CMHPG polymers exhibit a good thermal stability and can be cross-linked with a number of crosslinkers.

Benefits

Fracturing Fluids

Galactasol is a cold water-soluble anionic guar derivative used in oil and gas hydraulic fracturing fluids that exhibit low residue after break.

  • Good thermal stability
  • Excellent carrying capacity to support proppants
  • Produces highly viscous cross-linked gel
  • Outstanding salt tolerance
  • Excellent for cold environments
  • Compatible with other hydraulic fracturing additives
  • Cold temperature soluble
  • Low residue after break

Additional Information

Guar Gum

Straight guar is produced from natural guar without chemical modification. Guar derivatives range from a single derivatization producing hydroxypropyl guar (HPG) and carboxymethyl guar (CMG) to dual derivatization, producing carboxymethyl hydroxypropyl guar (CMHPG). Galactasol guar and guar derivatives are used as gellants to produce high cross-linked fracturing fluid viscosity. They can be     cross-linked with a number of transitional metal ions, including borates – ideal for proppant carrying capacity in created fracturing areas. The cross-linked gel can be broken by either acids, enzymes or encapsulated oxidizers. They can also be used in low-solids drilling fluids as a viscosifier and as a fluid loss reducer in both freshwater and brines, particularly in spud muds.
