ARCTech™ Casing Exit System


ARCTech™ Casing Exit System

TheWellEnTech ARCtech™ Casing Exit System is a Single Trip System that can be hydraulically or mechanically set. The unique patent pending design minimizes the length of a conventional system by combining tools that are normally run in conjunction, into a single assembly, without compromising on functionality or strength. The Wrapped Mill and Multi-Ramp are designed to complement each other for flexibility, ease of shear out, Mill starting and centre point elimination.This design delivers a smooth exit and beyond into the new well bore. The system enables 360 degree exit capability making it an ideal solution to a variety of casing exit scenarios.


  • Single Trip Design
  • Fully Retrievable
  • Short, robust construction
  • System & Mill Head Design eliminates need for knock off plugs & maximises dressed area
  • Number of Flow Ports on Mill Head are not restricted
  • No internal Burst Disc required
  • Retrieval Hook slot in whip face
  • Suitable for Hydraulic or Mechanical Setting
  • High torsional and tensile yield
  • Fully adjustable setting and shear values
  • Easy to assemble and redress
  • Sidetracks
  • Multilaterals

The WellEnTech Casing Exit System is easily assembled with the use of basic tools provided with the system. Packer hook up at hinge point& mill head hook up to ramp are all designed for ease and safety.Casing Exit system is run in hole to setting depth where theWhipstock is oriented using MWD or Gyroscope.With the mill head ports internally isolated the Anchor is set hydraulically via the setting port. Once anchor is set the internal mechanism will shear out the mill head isolating feature to establish full flow through the mill.Mill is then shear released from the ramp (shear can be up only or bidirectional as required) to enable milling of the casing exit and 10-15ft of rat hole. The result is a full gauge easily accessible window with minimal milling time.
