Western oil companies are reeling from a series of setbacks in Russia. Welcomed in under Boris Yeltsin, offering a new frontier for exploration and production, the likes of BP and Shell saw a chance to build up their reserves.

Some saw this as a wake-up call, which would usher in a dash-for-nuclear.
