Preserve ID, Keep Drilling on Target.

Enventure’s 8 x 9-5/8 inch MonoSET™ Openhole Clad (OHC) Systems are installed and expanded in the wellbore, without a loss of internal diameter (ID). Trouble zones can be strategically mitigated without anchoring into the previous casing.

The first commercial installation was completed in June 2010.
