摘要:
A method of increasing the near-wellbore permeability of porous formation comprises exposing formation to an elevated temperature of .�.400.degree..!. .Iadd.600.degree. .Iaddend.C. 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.
