Abstract

A method for reducing breakdown pressure at a formation includes detecting a tight reservoir formation in a well and providing hydraulic fracturing equipment assembled together as a hydraulic fracturing system at a surface of the well. The hydraulic fracturing system includes a fluid source containing a base fluid and fluidly connected to a blender and a pump and manifold system fluidly connecting an outlet of the blender to a wellhead of the well. The method further includes connecting a cooling system to the hydraulic fracturing system, using the cooling system to cool the base fluid to a cooled base temperature upstream of the pump and manifold system, pumping the cooled base fluid down the well to the tight reservoir formation, and using the cooled base fluid to lower a temperature of the tight reservoir formation and reduce a breakdown pressure of the tight reservoir formation.
