Organic Boron Crosslinker OB-320
CategoryHandbooks for Oilfield Chemicals

Product Overview:

Organic boron crosslinker OB-320 is prepared by the chemical reactions between borate and organic ligand (polyol, addition products of ethylene polyamine and ethylene oxide, etc.). It can crosslink with guar gum and its derivatives (HPG, CMHPG), fenugreek gum, sesbania gum and other galactomannan polymer, and form gel with good viscoelasticity, in preparation for water-based fracture fluid. This product can significantly reduce thickener dosage in fracture fluid. The fracture fluid gel prepared by this product has characteristics such as delayed crosslinking, low friction, resistance to shear, easiness to break and low hazards.
