ABSTRACT:
The present invention provides improved methods of treating subterranean formations using borate cross-linking compositions and borate cross-linked well treating fluids. The borate cross-linking compositions are basically comprised of a low viscosity hydrocarbon liquid, an organophillic clay, a slightly water soluble borate, a buffer and a dispersing agent.
