  • System for increasing productivity of oil, gas and hydrogeological wells
    Patent number: 7073587
    Abstract: A system for increasing the productivity of oil, gas and hydrogeological wells has means for cutting slots only in a near well zone so as to perform a partial unloading of the well and to remove a part of support stresses, and means for 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 in correspondence with the density of the formation.
    Type: Grant
    Filed: November 22, 2003
    Date of Patent: July 11, 2006
    Assignee: 1407580 Ontario Inc
    Inventors: Yakov Bassin, Valentin T. Grebennikov, Boris Goldstein, Anatoly N. Ivanov, Lon M. Marmorshteyn
  • Method of increasing productivity of oil, gas and hydrogeological wells
    Patent number: 6651741
    Abstract: A method of increasing the productivity of oil, gas and hydrogeological wells has the steps of performing a slot unloading, providing a cyclical treatment of a near well zone with a formation-treating substance, with a use of cutting slots, determining a region to be treated, selecting a corresponding volume of a treating technological composition, and introducing the volume into a formation to be treated, and subdividing the method into a two stages including a first stage performed by a partial slot unloading of a near well zone so as to remove a main part of support stresses, and a second stage of removing a remaining part of support stresses by a cyclical treatment of the well with a formation-treating substance with control by the density of the rock to be treated and performing a corresponding correction.

  • Method of oil well productivity increase
    Patent number: 5337825
    Abstract: Oil wells productivity is increased by cyclically treating a shaft-adjacent zone of the well with a seam-forming liquid which contains additional activating components.
