  • Method of opening productive formations and a working fluid provided therefor
    Publication number: 20130105163
    Abstract: A method of opening productive formations by slot-perforating includes providing a working fluid including water, an abrasive component, and an additive, supplying the working fluid at a high pressure towards a formation so as to cut slots and to provide an inflow of oil, gas and hydrogeological liquid from the formation into a borehole, and using the additive, so as to reduce density of the working fluid and therefore to increase a speed of jet of the working fluid due to increase of kinetic energy of particles of the abrasive component.

  • Slot-perforating system for oil, gas and hydro-geological wells
    Patent number: 8240369
    Abstract: A slot-perforating system for an abrasive-hydro-slotting of a near well-bore zone for establishing an inflow path between a borehole and a formation has an adaptor connectable to a tubing; a hydraulic block connected to the adaptor for regulating a speed of operation; a perforator providing a hydro-slotting, and a return block located between the hydraulic block and the perforator and returning the perforator an initial upper position.
