Abstract
A method of increasing the near-wellbore permeability of porous formation comprises exposing the formation to an elevated temperature of 400C or greater to cause dehydration of the clay lattices, vaporization of any blocked water, mud filtrate or other fluids, and/or destruction of the clay structure.
