Saltel Industries installed eight expandable steel Casing Patches in Latin America. The objective was to isolate excessive C02-producing sets of perforations in the same oil producer well.

The weather conditions, quite unusual, held up significantly the operations, with -15 degC temperature, and strong winds up to 120 km/h).

As a result, the 4.5in patches reinforced were successfully installed between 1,400 and 1,537m depth, and covered the eight targeted sets of perforations in a 5in casing.
