  • Sakhalin extended-reach well pushes ERD envelope to a world record

    Michael W. Walker

    Extended-reach drilling (ERD) offers economical access to reserves that were previously out of reach. This access can be achieved from existing infrastructure, with the added benefit of a reduced environmental footprint. ExxonMobil, as operator of the Sakhalin I project, recently drilled and completed nine extended-reach wells at Odoptu field from shore, culminating with the world record extended-reach OP-11 well. The well reached a total depth of 12,345 m (1,784-m TVD and 11,479-m vertical section) in 60 days with less than 1% NPT.
