"Maxxwell Production Inc." is the company which provides the service of intensifying productive debits of oil, gas and injection wells by applying the method of slot discharge productive layers, using special exclusive slot perforation hydraulic engine equipment (hydro-slotting perforation technology) by cutting longitudinal opposite vertical slots along the well bore with a large area of contact with the well producing formation. The method has fine proven itself in oil and gas wells in metamorphic, sedimentary rocks, shale (including clay), cemented sandstones and finely-interbedded layers, with proximity of water reservoirs (flooding risk) as well as in recovery of small-debit, non-producing (abandonment, idle, plugged) wells.
