摘要: The present invention provides a method of treating subterranean formation utilizing gelled fluid containing galactomannan gum and crosslinking agent comprising source borate ions delayed crosslinker Ti(+4) or Zr(+4) ions. combination agents yields viscous at elevated temperatures having viscosity higher than attainable by either alone as the result additive effects agents. enhanced facilitates transport placement proppant material in formation.
