Radial Jet Drilling (RJD)

Radial Jet Drilling (RJD) is a reliable stimulation method applicable in new or old well enhancement. The procedure is simple, a drill bit (Milling bit) is used to open a 20-24 mm hole on the casing, and then using a jetting hose (pressurized fluid) connected with coiled tubing to drill several horizontal holes at different depths and directions of the formation. The diameter of jetted horizontal hole is around 40-50mm and length is up to 100m.


Benefits of RJD

  •   Increases production rate and recoverable reserves (especially from marginal wells).
  •   Extend the life of a well.
  •   Allows directional treatment of wells e.g. acid, steam, CO2, etc.
  •   Improves injection rates in water disposal/injection wells for water flooding recovery techniques.
  •   Allows multi-layer application in thicker reservoir zones.
  •   No need for large, expensive rotary rigs.
  •   No mud pits that can damage the environment.
  •   No casing milling equipment necessary.
  •   Average operation duration is a few days per well.
  •   No need to change well-bore configuration.
  •   Short Operation Cycle and Low Cost
  •   No slurry is needed and no great damage to the layer.
  •   Little fluid consumption (10~20 m³ per layer).
  •   Holes on the casing have less damage than perforation on casing and less impact on casing strength.
  •   Cost effective and environment-friendly
  •   It can be applied in both new and old wells   

Technical Advantages

  •  Establishing and increasing seepage channel for the reservoir
  •  Intersecting natural fractures thereby allowing faster zonal drainage
  •  Forming micro to macro fractures around the created hole
  •  Deep acidizing and directional fracturing can be achieved
  •  Removing block around area near wellbore and far away from wellbore
  •  Reaching past conventional perforation distances into virgin parts
  •  Reforming the formation with acidizing and fracturing operation
  •  Expanding drainage area for a single well
  •  Reduces flow resistance by increasing drainage radius
  •  Delivery of adjunct treatments (e.g. acid, CO2, nitrogen, heat) far into the zone
  •  Adjusting stereoscopic well pattern
  •  Capability of multi-directional jetting across various levels
  •  Improves penetrability beyond wellbore formation damage
  •  Improves the efficiency of geomechanics-based and direction-sensitive operations
  •  Has the capability to apply different fluids and chemicals as a jetting fluid
  •  It is also used as an alternative to frac work as well as a method to directionally control frac and other chemical or steam injection applications.
  •  RJD between the intervals of perforations can be done with no problem.
