Energy explorers, undeterred by BP’s experience
, are striving to meet the challenge of drilling in ever-deeper and more complex places. BP
and Maersk are working on designs for rigs that can operate in ultra-harsh environments
. Shell's (RDS.A
) $5B Olympus rig
is ready to have its legs fitted. Statoil (STO
) is moving on a $7B project
in the North Sea to tap heavy oil discovered in the 1980s but is only now accessible.
