ABSTRACT:
The present invention provides borate cross-linked well treating fluids and methods of preparing and using the fluids in treating wells such as fracturing subterranean zones therein. The improved cross-linked treating fluids are basically comprised of water, a hydrated galactomannan gelling agent and a borate composition for buffering the treating fluid and cross-linking the hydrated galactomannan gelling agent comprised of water, a soluble boron source and an alkanolamine or alkylamine.
