SET Open Hole Clad

In open hole scenarios, a SET® Open Hole Clad can isolate zones without the need to tie-back into previous casing.

The OHC System uses components common across all of Enventure’s product lines.  The liner is made up to an inner work string and run in the hole to the specified depth.  Hydraulic pressure through the inner string provides the force necessary to expand the liner from the bottom up.  This allows the liner to shrink predictably from the top of the string and doesn’t affect the setting depth once initiated.  Hydraulic expansion minimizes wall thinning in the liner and results in superior post-expansion burst and collapse values.

Field Applications

SET® Openhole Clad liners are specifically designed to provide zonal isolation. Applications include stabilizing the openhole, isolating water zones, and mitigating lost circulation zones. The heart of the system is the elastomer seals. Because the system seals directly against the formation there is no need to tie back into the base casing.  Both standard and swellable elastomer seals are available. These elastomeric components are bonded directly onto expandable liner pup joints. The seals expand with the liner and clad into the formation, using compression to form a barrier. Multiple elastomeric seals can be placed at various locations along the expandable liner to provide multiple zonal isolation.
