Caspian region isn't as rich in gas as we tend to think and Shakh-Deniz deposit is not enough to fill in Nabucco West! This is reality, rather discouraging one, having nothing in common with the "forecasts and estimates by experts".
Why do you think RWE has dropped this project? The so called "second development stage" is just a PR myth! The deposit will be exhausted by 2016, believe you me! I just saw with my own eyes the data of geological research, the real reports, not the estimates of "specialists".
Wella..... one such a specialist during a friendly get-together in some pub put it plain. "For the money they gave me I could voice whatever scientific prognosis", he said. He failed to explain who they were.
You see, one more litmus paper in the context the BP strong desire to sell its share in the project. They are only scary such a massive step could ruin the market and selling it in portions would bring inevitable losses. So they are staying idle for a while. But it can't last forever imo. Sooner or later it will occur!
