Since the casing string is intimately linked to the production lifespan, the maintenance and repair of well tubulars is a major concern for operators. Damaged casings mean both serious hazards to QHSE and potential jeopardy of the production rates. Mature and new wells are both subject to such threats, and may require an intervention. Casing repair prevents not only blow outs, collapse of the damaged strings, but also can eliminate the need for a major workover.
The Saltel Expandable Steel Casing Patch (SES Patch) allows restoring casing integrity, optimizes the well's production, and prevents fluid or gas migrations in the annulus. The Patch once set, leaves large ID access to the well for most standard downhole tools. Saltel Patch is a pressure-resistant inner lining which allows the end user to avoid plug and abandonment decisions.
