A £500m battle is welling up over a picture postcard piece of English countryside.
An area of ancient woodland in the rolling hills of the South Downs in West Sussex, Markwells Wood is a world away from rain-lashed oil rigs in the North Sea or sun-bleached oil refineries in the deserts of Saudi Arabia.
Yet hidden behind the trees is one of the UK's newest onshore oil wells.
With testing work continuing, the owner, London-based Northern Petroleum, estimates it could produce about five million barrels of oil.
