The invention relates to a method for drying out rock containing immobile formation water within the encroachment area of natural gas deposits and gas reservoirs, which produce less than 50 l of water per 1000 m3 (Vn) of extracted natural gas. According to said method, the water-bearing rock is rendered hydrophobic by means of a dispersion containing the following components: (A) a water-repelling active substance, (B) a hydrophilic dispersing agent which can be mixed with water, and, if needed, (C) a dispersing additive.
