Harbour says Tolmount gas reserves could be downgraded

LONDON (Reuters) - Harbour Energy on Thursday said that net reserves at the Tolmount UK North Sea gas project could be downgraded to between 20 million and 30 million barrels of oil equivalent (boe), according to preliminary estimates.

This would be 25-50% lower than expected when the project received a final investment decision, a presentation slide showed.
