hydraulic lateral drilling* New technique of lateral drilling
* High Pressure Fluid

* Piercing perpendicular to shaft
* With flexible pipe (coil tubing)


* Increase the rate of marginal well production:
* Reduced formation damage
* Elimination of permeability barriers
* Improvement of the effective radius of drainage


* Diameter: 2 inches
* Length: 300 feet
* Bending radius: 30 cms

How It’s Done

* Two stages:

Drilling casing with a 11/16 inch drill.
The actual drilling of the formation hydraulic ejector with a 5 / 8 inches.

* Oriented on training and directed perpendicular to the pit through a deflector shoe

Conventional vs lateral hydraulic drilling

World application


* This new technology allows to increase the production rate and thus recoverable reserves from marginal wells.
* Applicable in small reservoirs thicknesses.
* Has a greater effectiveness in older wells and low productivity.
* Not required large and expensive well service equipment.
* No additional equipment is required for the drilling of the casing.
* No need for extra stimulation.
* The operation has an average duration of two days per well.
* Not required for making specialized registries.
* No need to change the mechanical configuration of the well.
