leaking casing remediation to prevent fluid migration and restore integrity
Leaking casing repair in oil and gas producing wells is capital for operators seeking to avoid groundwater contamination or methane migrations into the atmosphere.
There are various explanations to a leaking casing (see also damaged casing) :
- casing split,
- corroded casing sections,
- damaged couplings…
Saltel Expandable Steel casing 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. The Patch is a pressure-resistant inner lining allowing to avoid plug & abandonment decisions.
