When considering workover operations, the client must cope with simple and cheap well intervention or complex and expensive remedials. Numerous workovers are generated each year for enhanced recovery or tubular (and cement) integrity purposes. Saltel Xpandable Patch is one of the best alternatives to reach such objectives, since it guarantees the best internal diameter (ID) post-setting, while extending the lifespan of the well. Saltel patch being now a solid field-proven solution to troubleshoot downhole erosion and corrosion issues – that usually compromise the well integrity, it is obvious for operators to include it in their workover strategy to maximize their well’s life cycle.

Once installed, Xpandable steel Patch brings a strong added-value to the well production. Consider it drastically economic in the workover process, since it combines smooth entry – chamfered extremities,  with maximized internal diameter for better flow-rates when the well is back to production.

Which workover applications with Xpandable steel Patch

Workover options with Xpandable Steel Patch has been extended from ageing asset and mature well applications to new well applications. Damaged completion modules requiring maximum ID can now be isolated with Xpandable steel patch: damaged frac ports, open and blocked sliding sleeves, damaged  DV tools, ICDs, sand screen sections. The patch will be set and mold to the irregular geometry of the tool to cover, guaranteeing high internal differential service pressure ratings once set.
