Expandable Steel Patches
In 2005 Saltel Industries started to develop a new expandable technology using high pressure Inflatable Packers for expanding short lengths of tubular. Saltel Industries sells and sets these lengths of tubular worldwide as SES Patches (Saltel Expandable Steel Patches). The high R&D Company profile, innovation and the creative use of technology brought about a new and simple solution for Expandable applications. PDO conducted its first Field Test operations in Oman in 2008, to isolate an open hole zone and successfully cure total losses during drilling.
In the years 2008 and 2009 the development focused on the qualification and industrialization of the process from manufacturing to the setting in the well. Saltel Industries developed inflatable packs, down hole tools, surface equipment, and software for oilfield applications, which were then qualified in test dummy wells. 2010 saw the beginning of large-scale marketing of the SES Patches. Over 500 SES Patches are now in operation in Europe, North America, Russia, Africa and the Middle East, ranging in length from 3 to 66 m, mainly on land but also offshore.
