                              Eccentric(ODEX) Casing System


                              Features: 

                              • Longer operating life and excellent anti-wear properties.
                              • Strengthen the structural strength,easy to operate.
                              • Stable and reliable performance,high drilling speed.


                              Operation Procedure:

                              1. When drilling starts,the reamer opens and enlarges the hole to drive the casing shoe and casing tube down.

                              2. When the drilling in over-burden formation is finished,reverse the rotation to close the reamer,then the assembly can be pulled up through the casing tube.

                              3. The casing tube can be left in the hole,or can be pulled out by means of grout sealing materials.

                              4. Use the normal drilling tools to drill and achieve to the desired depth.
