Study sees harmful hunt for extra oil

All the world's extra oil supply is likely to come from expensive and environmentally damaging unconventional sources within 15 years, according to a detailed study.

This will mean increasing reliance on hard-to-develop sources of energy such as the Canadian oil sands and Venezuela's Orinoco tar belt.

A report from Wood Mackenzie, the Edinburgh-based consultancy, calculates that the world holds 3,600bn barrels of unconventional oil and gas that need a lot of energy to extract.

The study makes clear the shift could come sooner than many people in the industry had expected, even though some major conventional oil fields will still be increasing their production in 2020. Those increases will not be enough to offset the decline at other fields.

"It becomes unclear beyond 2020 that conventional oil will be able to meet any of the demand growth," Wood Mackenzie said. The report added that natural gas products such as liquids and condensate would also become important sources of growth.

The increasing reliance on unconventional oil will require a substantial reshaping of the energy industry.
