Multilateral Completion

Perfobur supplies equipment, delivers service support for completion of multi-lateral wells and provides sidetracking in existing wells which ensures a guaranteed access to each channel.

MLW Key Advantages

 

Key advantages of Perfobur MLW technology

  • Kickoff for any depth with no need to be supported by the bottom-hole (no need to install and sub-drill the supporting bridge)
  • Kickoff towards the specified direction by using the azimuth
  • Kickoff on the first try
  • Borehole connection resistance to complications in equipment passing through holes
  • Reduced duration of sidetracking kickoff
  • Operation cost with respect to risks is multiply less

 

Equipment package

  • Hydraulic anchor with its working element made of a laterally shaped pipe, which body is covered with hard-alloy inserts. Intended to run whipstock to the target depth supported by open borehole walls.
  • Whipstock with an axial hole for a hydraulic system tube. Intended for deflection of arrangements.
  • Run-in shoe with a hydraulic system. Intended to run the whipstock and the anchor to the target depth and transmit pressure to the anchor.
  • A set of devices for orientation using a geophysical lift. At the final stage, the orientation system is developed without applying the geophysical lift.
  • A set of cutters - window cutter, expanding cutter and calibrating cutter - for sliding from the whipstock and deepening into the rock.
  • Tricone bit for deepening into the rock when no cutters are available. Installed instead of the window cuter, completed with expanding and calibrating cutters.

 

Advantages prior to kickoff from the cement bridging

  • Kickoff for any depth with no need to be supported by the bottom-hole (no need to install and sub-drill the supporting bridge)
  • Kickoff towards the specified direction by using the azimuth
  • Kickoff on the first try
  • Hole connection resistance to complications in equipment passing through holes
  • Reduced duration of sidetracking kickoff
  • Operation cost with respect to risks is multiply less
