Abstract
Low permeability formations are hydraulically fractured with a fracturing fluid which includes a material capable of (1) bonding fine formation particles to prevent movement of the particles into and within the formation and (2) forming a permeability-reducing skin at the formation/fluid interface to reduce fluid leak-off into the formation. The stabilizing and fluid leak-off reducing material is comprised of a water soluble polymer and an alkaline potassium salt.
