Jan 16 (Reuters) - Antrim Energy Inc said two of its oil fields in the North Sea went off production following a leak in an oil pumping station that is part of Britain's North Sea Brent pipeline system, sending its shares down 4 percent.
The leak at one of the legs of the Cormorant Alpha platform, operated by Abu Dhabi oil company Taqa, has disrupted production at more than 20 oil fields in the northern North Sea, Antrim said.
Antrim said production was stopped at the Causeway field and the cormorant East field and that all pipeline infrastructure associated with the Cormorant Alpha platform were shut in.
