Isolate the trouble zone while conserving hole size by planning solid expandable technology into the well design; optimize wellbore trajectory and reduce risk in sidetrack drilling operations.
In 2009, a global super-major operating out of Borneo experienced problems with a well it was running from a drillship in over 5,000 feet of water off of the Sarawakan coast. An initial exploration well working a straight hole in a shale formation, the operator encountered an unstable...
In cased-hole environments, ESeal Liner systems provide a solution to mitigate troubled casing intervals in onshore and offshore applications.
Enable offshore exploratory well to reach total depth (TD) with optimal hole size after base casing was set higher than expected.
