It’s the end of the year, which means it’s time to peer once again into my crystal ball and see what the future holds. It’s also the time when I like to look back at my previous forecasts and see how they held up. So without further ado, here are my forecasts for oil and gas prices in 2013.

Oil

I can’t recall a time when analysts’ oil price forecasts for the coming year were so divergent. At the high end, Goldman Sachs and Morgan Stanley think the global oil benchmark Brent will average $110 next year, while a few other analysts think it will average more than $115. At the low end, Raymond James analyst Praveen Narra sees Brent averaging just $80. Deutsche Bank says the spread between analysts is even wider, with a $50 gap between the high and low forecasts.

None of these analysts have particularly stellar track records though. Goldman recommended in February that their clients go long on U.S. oil at $107.55, very nearly the peak price of the year (it was only exceeded four other days this year, in February and March) and an excellent time to sell. In October 2011, Raymond James forecast an $85 average for the U.S. benchmark WTI in 2012; it currently averages $94.35 for the year.

Analysts at the low end seem to be particularly carried away. Francisco Blanch of Bank of America Merrill Lynch told Bloomberg that WTI is their “big short” for next year, and speculated that WTI could drop as low as $50 a barrel within the next two years. Citigroup’s Ed Morse asserts that U.S. producers can break even down to $72 a barrel, and would keep drilling new tight oil wells at $60 because they’re hedged.

I’m inclined to short those shorts. Some U.S. producers may be hedged under $70, but not 100 percent of U.S. production, and various sources say that at $70, U.S. tight oil production would become unprofitable and cease. Yes, overly bearish sentiment can drive prices below marginal production costs for awhile, as they have done in the past, but even if that were to happen in 2013 (which I doubt), I don’t think it would last for more than 3 to 6 months. Indeed we should hope that producers aren’t using hedges as a way to extend production long past the point of profitability, as shale gas producers have done for the past two years, because it would ultimately starve investment in future production and kill the tight oil growth trajectory.

My outlook for oil prices is essentially unchanged from my June forecast: Oil producers will cling to the “narrow ledge” for another year. As I predicted at that time, oil prices did in fact move back up in the second half of the year; OPEC kept output unchanged; Israel did not bomb Iran; and spare capacity increased. On the basis of that model, I would probably choose a $110 average for Brent in 2013, but I’m inclined to reduce that forecast slightly for the following reasons.

First, I expect WTI to continue to remain at a $10-15 discount to Brent, down from $17 this year, due to the ongoing glut at the Cushing, Oklahoma hub. By comparison, Goldman Sachs thinks the Brent-WTI spread could fall to as little as $4.50. Enbridge says that its Seaway pipeline will ramp up from 150,000 barrels per day this year to 400,000 barrels per day in January, carrying more oil from Cushing to Houston and helping to relieve the backup over the course of the year. However, if the latest outlook from the U.S. Energy Information Adminstration (EIA) is in the right ballpark and U.S. tight oil production increases by 300,000 barrels per day in 2013, it will largely offset the increased offtake capacity. A sustained wide discount of WTI to Brent should drag the latter down slightly.

Second, global demand growth is modest, and supply should be more than adequate. The EIA expects global consumption to rise by nearly 1 mb/d (million barrels per day) in 2013, while OPEC production rises 0.65 mb/d and non-OPEC production rises by 1.3 mb/d, with essentially all of the latter increase coming from U.S. tight oil and Canadian tar sands. I might quibble with those numbers, but I am comfortable with the notion that supply will be sufficient to keep prices moderate.

Third, global spare production capacity is well above the price-spike-inducing danger zone of roughly 1 percent, and should remain comfortable. It’s currently around 2 mb/d, according to EIA, and could grow to 3.3 mb/d by the second quarter of 2013, more than 3.5 percent of demand.

My call is that Brent will average around $105 in 2013, and WTI will average around $90 - $95.

For the record, I once again won the bet this year with some oil-literate friends by predicting at the start of the year that Brent would average $105 in 2012; the actual average as of this writing (a week before press time) is $111.72. Curiously, that’s just $0.60 lower than where Brent traded on the first trading day of 2012.

Gas

U.S. gas supply appears to be going nowhere. As I detailed in October, the EIA expects total US gas production to remain basically flat throughout 2013 at around 69 billion cubic feet per day.

At the same time, demand continues to increase. Low natural gas prices continue to push coal out of the power generation business, a trend I highlighted one year ago. The latest casualty is Edison Mission Energy, which operates coal-fired power plants in Illinois and three other states. The company filed for bankruptcy protection on December 17, citing the difficulty of competing with natural gas-fired power plants as a major factor.

Demand for natural gas as a trucking fuel is also picking up, albeit from a fairly low level. Clean Energy Fuels, a leading builder of natural gas refueling stations co-founded by T. Boone Pickens, says it’s on track to complete the first stage of “America’s Natural Gas Highway” with 70 LNG (liquefied natural gas) truck refueling stations completed this year, and another 70 to 80 stations slated for construction in 2013. As I calculated last January, Pickens’ estimate that converting transport trucks to natural gas could cut 2 mb/d from our oil demand might translate into roughly 1.5 trillion cubic feet (tcf) of gas consumption annually, or about a 6 percent increase in total U.S. gas demand.

EIA expects total U.S. gas consumption to rise to 25.4 tcf in 2012, a 4.8 percent increase over 2011 levels, but then to decline slightly in 2013. Gas-fired power generation was exceptionally high in 2012 due to air conditioning demand during an unusually hot summer and EIA apparently expects more normal summer temperatures next year; on that point I’m skeptical.

Natural gas prices still haven’t climbed back to the minimum $4 threshold of profitability, with the January 2013 contract at $3.36 per mcf as of this writing. My forecast is for gas prices to approach $4 by the end of 2013, simply because unprofitable endeavors don’t go on forever and after two years this one feels about played out. EIA expects gas prices to average $3.68 in 2013, which (amazing!) is precisely the average of today’s price and $4.

Unfortunately for climate hawks who have been encouraged to see U.S. carbon emissions fall as power generation switched from coal to gas in recent years, at $4 gas some of that switching will be reversed. I was not able to quantify how much gas-fired capacity could switch back to coal, but reviewing the EIA’s list of all US power plants showed that about 11 percent of them can use both natural gas and coal.

As for my predictive accuracy on gas in 2012, I pretty much nailed both the end of the production growth trajectory and the bottom in gas prices.

The Goldilocks zone

The most difficult part of price forecasting is unpredictable events like hurricanes and geopolitical upsets. But unlike this time last year, when I was shaking my head in amazement at the extraordinary events of 2011, I actually feel fairly sanguine about 2013.

2012 proved to be a remarkably stable year, with many of the uncertainties I contemplated failing to materialize and/or exert much influence on oil prices. I did anticipate another major natural disaster, so Hurricane Sandy wasn’t really a surprise. Likewise for the still-unfolding effects of the Arab Spring.

Perhaps I was reflecting recency bias then, and perhaps I’m making the same error now, but at the moment I don’t see any major geopolitical events influencing oil prices next year. From where I sit today, 2013 looks manageable. Oil prices should stay in the Goldilocks zone — neither high enough to kill demand nor low enough to kill supply — and gas prices should slowly rise back up to the point where future shale gas production seems less imperiled than it has this year.
