PCT No. PCT/EP97/07104 Sec. 371 Date Jun. 10, 1999 Sec. 102(e) Date Jun. 10, 1999 PCT Filed Dec. 18, 1997 PCT Pub. No. WO98/27314 PCT Pub. Date Jun. 25, 1998The invention relates to a process for drying out rock containing immobile formation water in the intake radius of natural gas wells and gas storage wells which deliver less than 50 l of water per 1000 m3 (S.T.P.) of natural gas produced, in which a dispersion comprising the components A) a water-repellent active compound, B) hydrophilic water-miscible dispersion medium, with or without C) a dispersant renders the water-containing rock hydrophobic.
