EnCore Oil makes North Sea find

British oil and gas explorer EnCore Oil said yesterday it found a large oil column and hydrocarbon-bearing sands at a well in the Cladhan field in the UK North Sea, six months after it had hinted that the discovery could be commercial. EnCore said it found oil-bearing sandstones at the upper Jurassic layers of the reservoir, after drilling the well to a depth of 12,252 feet.
