AN Italian oil and gas giant has bucked the gloomy trend in the North Sea by reporting an increase in production in the UK.

While experts have warned that output is set to plunge in the UK following the sharp fall in oil prices, Eni highlighted the value of its interests in the country in its fourth quarter results.

The company said production increases in four countries including the UK more than offset declines in output from mature fields in its global portfolio.

Eni did not give details of UK production levels. However, it highlighted "major increases" in the production of liquids, such as oil and gas condensate, in the UK.

Last week Bank of America Merrill Lynch said the UK North Sea is especially vulnerable to the effect of the plunge in oil prices since June because too much production comes from old fields that are expensive to run.

The bank forecast firms will slash investment in the area.

Eni is renowned for its activities in countries such as Angola and Nigeria.

However, the company has remained active in the UK since 1964. It has stuck by the North Sea through previous oil price cycles.

On its website Eni says it has interests in 13 production areas in the UK, including the giant Elgin/Franklin development around 130 miles east of Aberdeen and fields in Liverpool Bay.
