摘要：
The present invention relates to environmentally friendly delayed crosslinking complexes that are useful in subterranean treatment fluids. One embodiment of the present invention provides a method of providing a treatment fluid having a first viscosity and includes: an aqueous base fluid, a viscosifying agent, a delayed crosslinking complex having : a metal and a ligand, the ligand having at least one hydroxyl group and at least one carboxylic acid group; and placing the treatment fluid in a subterranean formation. In some embodiments, the delayed crosslinking complex is compliant and/or the viscosifying agent is compliant.
