The new floor

The new floor for oil prices is being set increasingly by the production cost of these unconventional liquids. A few decades ago, we could produce conventional oil profitably in the U.S. for under $15 a barrel. But those days are long gone for the U.S., and for most of the world (except a few old fields in places like Saudi Arabia). As every major oil company has admitted in the past few years, the age of easy and cheap oil has ended.

As the cheap oil from old mature fields is depleted, and we replace it with expensive new oil from unconventional sources, it forces the overall price of oil up. This is because oil prices are set at the margin, as are the prices of most commodities. The most expensive new barrel essentially sets the price for the lot.

Research by veteran petroleum economist Chris Skrebowski , along with analysts Steven Kopits and Robert Hirsch, details the new costs: $40 - $80 a barrel for a new barrel of production capacity in some OPEC countries; $70 - $90 a barrel for the Canadian tar sands and heavy oil from Venezuela’s Orinoco belt; and $70 - $80 a barrel for deepwater oil. Various sources suggest that a price of at least $80 is needed to sustain U.S. tight oil production.

Those are just the production costs, however. In order to pacify its population during the Arab Spring and pay for significant new infrastructure projects, Saudi Arabia has made enormous financial commitments in the past several years. The kingdom really needs $90 - $100 a barrel now to balance its budget. Other major exporters like Venezuela and Russia have similar budget-driven incentives to keep prices high.

Globally, Skrebowki estimates that it costs $80 - $110 to bring a new barrel of production capacity online. Research from IEA and others shows that the more marginal liquids like Arctic oil, gas-to-liquids, coal-to-liquids, and biofuels are toward the top end of that range.

My own research suggests that $85 is really the comfortable global minimum. That’s the price now needed to break even in the Canadian tar sands, and it also seems to be roughly the level at which banks and major exploration companies are willing to commit the billions of dollars it takes to develop new projects.

Production costs soaring

Indeed, production costs have been soaring since we began relying heavily on unconventional fuels. This is the direct result of rising prices for essential inputs like steel and diesel fuel (whose cost inflation is directly tied to the rising cost of the underlying fuels like hard coal and oil), of which ever-greater amounts are needed to drill and complete a new well. Adding another mile of high-specification steel pipe to a deepwater well, or another thousand feet of drilling and well casing for a deeper tight oil well, adds significant costs.

Globally, the cost of drilling a new oil well has gone parabolic:
