Abstract
The present disclosure relates to a crosslinking composition for use in crosslinking an aqueous suspension of guar, for use as a well treatment fluid and/or proppant carrier fluid for natural gas extraction. The present crosslinking composition is an aqueous suspension of hydroboracite. The composition may also comprise varying amounts of borax, canola oil, xanthan, glycerol, and/or NaOH. The composition may be selected to effect a desired delay in the crosslinking reaction in order to customize the viscosity and reaction time to the method of use, thereby maximizing proppant delivery while minimizing pump pressure.
