How Falling Oil Prices Will Strangle the Shale Oil Boom
Thanks to Bob Wenzel @ EconomicPolicyJournal.com
Economist magazine explains:
The boss of Continental Resources,
Harold Hamm (whose fortune has dropped by $11 billion since July), has said he
can cope as long as the oil price is above $50. Stephen Chazen, who runs
Occidental Petroleum, has said the industry is “not healthy” below $70. The
uncertainty reflects the diversity of activity. Wells produce different mixes
of oil and gas (which sells for less). Transport costs vary: it is cheap to
pipe oil from the Eagle Ford play, in Texas, but expensive to shift it by train
out of the Bakken formation, in North Dakota. Firms use different engineering
techniques to pare costs.
Two generalisations can still be made. First, in the very near term, the industry’s economics are good at almost any price. Wells that are producing oil or gas are extraordinarily profitable, because most of the costs are sunk. Taking a sample of eight big independent firms, average operating costs in 2013 were $10-20 per barrel of oil (or equivalent unit of gas) produced—so no shale firm will curtail current production. But the output of shale wells declines rapidly, by 60-70% in their first year, so within a couple of years this oil will stop flowing.
Second, it is far less clear if, at $70 a barrel, the industry can profitably invest in new wells to maintain or boost production. Wood Mackenzie, a research consultancy, estimates that the “break-even price” of American projects is clustered around $65-70, suggesting many are vulnerable (these calculations exclude some sunk costs, such as building roads). If the oil price stays at $70, it estimates investment will be cut by 20% and production growth for America could slow to 10% a year. At $60, investment could drop by as much as half and production growth grind to a halt.
