There can be no negative effect (or) contamination of the lake. I base this certainty on the laws of physics and practical experience (of the use of similar techniques elsewhere).

The drilling will continue. We are not violating any rules. If our activities don?t suit people, what can I say?

I'm disappointed, ... I spent several years there. I was one of the founding members of their Institute for Theoretical Physics. I would have thought they'd be proud to claim me.

This is a solid project that adds certainty to our production profile beyond 2007. The North Sea is important to our overall growth strategy, and Ettrick is a stepping stone to growing a sustainable business in this area.

In a universe of ambiguity, this kind of certainty comes only once, no matter how many lifetimes you live.
