Shell CEO sees long-term oil price at $90/barrel

LONDON (Reuters) - Oil prices should reach a long-term equilibrium of $90 per barrel, Royal Dutch Shell's Chief Executive Ben van Beurden told a conference call on Thursday.

He said it was impossible to predict when prices would return to those levels and said oil prices were poised to remain volatile in the mid-term.
