ABSTRACT:
A method of gelling a guar or derivatized guar polymer solution utilized to perform a hydraulic fracturing operation includes the step of adjusting the pH of the guar or derivatized guar polymer solution to between about 8.5 and 12.5. After adjusting the pH, an anhydrous boron compound or a sparingly soluble borate suspended in a mineral spirits-resin solution or an oil-resin solution is added to the guar or derivatized guar polymer solution. The guar or derivatized guar polymer solution and the anhydrous boron compound or the sparingly soluble borate solution suspended in the mineral spirits-resin solution or the oil-resin solution is then pumped into a subterranean formation under sufficient pressure to cause a fracture in the formation rock.
