  • +7 (34767) 7-19-00

Wireline Shock-Depression Bailer


  • recovery stimulation of production wells and intake capacity increase of injection wells by implosive hydrodynamic effect on perforation zones
  • bottomhole cleaning from loose and viscous sludge


  • fluid and gas sampling at specified depth to determine physical and chemical properties and compositional analysis
  • hydrostatic pressure control along wellbore
  • tripping small metal objects out from bottomhole, including capsules with radioactive sources
  • bottomhole and sump cleaning from loose and viscous sludge
  • cleaning of perforation channels and near-wellbore zone from mechanical particles that reduce flow properties of perforation interval


  • operation parameters monitoring from the surface
  • high speed of operation
