Wellwell:: below an ESP
Actually there is a more expensive option and that's to bring in a rig for a workover to get access below the ESP's. If the ESP's fail this is the option we will be required to consider although natural flow would mitigate some of the lost production in this worst case scenario. In a sub-hydrostatic well it's the worst nightmare and there are plenty of examples in the North Sea where this has happened.

Surely that’s the reason they are using dual ESPs if one fails use the other as back up..... If both fail it would be a work over completion !
