Northside: The Unexpected Rheological Behavior of Borate-Crosslinked Gels (SPE 140400)
Borate-crosslinked polymeric fluids have been used for hydraulic fracturing treatments for more than forty years. The knowledge of fracturing fluid viscosity behavior is one of the most important pieces of input data for hydraulic fracturing treatment design and evaluation.
It has recently been discovered that pumping pressures encountered during hydraulic fracturing treatments can materially reduce the viscosity of a borate-crosslinked fluid. The loss in viscosity, depending on fluid formulation, temperature, and pressure can range from nothing to significant, resulting in a fluid with the viscosity of the uncrosslinked polymer solution (linear gel). This presentation highlights the results of recent testing of a variety of aqueous-based fracturing fluid systems along with detailed results for various borate-crosslinked fluids commonly commercially available.
