Zusammenfassung:31 A method and a system for of increasing the productivity of oil, gas and hydrogeological wells includes cutting slots only in a near well zon e so as to perform a partial unloading of the well and to remove a part of support stresses; and cyclically treating well with a formation-treating substance so as to remove a remaining part of the support stresses, with controlling a density of a formation and correcting the cyclical treatment i n correspondence with the density of the formation.
