摘要

A method for increasing the fluid permeability of a subsurface terrestrial formation having at least one fracture extending from a borehole radially within the formation, characterized by injecting into said borehole and from there in said fracture, a fluid suspension of a solid particulate forming material having a maximum average diameter greater than about 0.76 mm and a concentration in said fluid sufficient to deposit in said fracture less than the number of particles that will form a single layer of particles in physical contact with each other and greater than the number of particles that will break giving small fragments due to the pressure of the walls of said fracture.
