Abstract
We introduce a new way to repair the casing affected by severe damage, even long rupture casing. These techniques consist to pump cement through a special design of cement retainer and fiber pipes call ERFV (Epoxy Reinforced Fiber Glass), to fill the annular space between the casing and ERFV pipes. The ERFV are used as a guide for a special pilot mill (a mill with a nose of smaller diameter). Thus, achieve the integrity, the passage and the continuity of the well.
This paper will explain the method to repair severe casing damage and show the results of wells repaired.
