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.
BP experienced losses while drilling a development well due to weak sand formation directly below the 13-3/8in. shoe. Multiple attempts were made to stem the losses - all without success.
A solution was required to isolate the weak sand formation and enable drilling to continue with higher...
An Operator required restoring integrity to their 13-3/8" 72 lb/ft casing on a suspended Central North Sea well.
Enable offshore exploratory well to reach total depth (TD) with optimal hole size after base casing was set higher than expected.
