Roiboi,
I imagine it came as a bad surprise for them when they started drilling in France.
There is no desert outback there, where you can drill a well every 1/4 mile.
Most of the land is in use and environement standards are high. Drilling prices have decreased lately because of the crisis but it remains expensive.
If I was Yorkville I would keep the shares.. (my only advice here ;-))
Thanks.
