Chevron Canada has begun drilling the countryÔÇÖs deepest offshore oil well in the North Atlantic offshore Newfoundland. The exploratory well, known as Lona 0-55, is expected to establish a new record in Canada with a water depth of 2,600 meters. Located in the largely unexplored Orphan Basin, an area spanning 100,000 square kilometers, it lies around 430 kilometers north-east of Newfoundland's capital St. John's. Chevron Canada has a 50 percent stake in Lona 0-55.
