News of the future was, in my youth, something that one found by crossing the palm of a lady in a dark tent with a piece or two of silver (or the modern equivalent) at one of the fairs that came to town. Such opportunities still exist, with all the caveats that existed back then likely still being in force. However, projecting the future, whether of the weather, the likely corn crop this year in the United States, or the production of crude oil by the nations of the world has become a much bigger business with copious tables, graphs and theories replacing the rather worn pack of cards or crystal ball of my youthful experience.

Our part of the world underwent a drought last year severe enough to kill several trees in our yard, for example, as well as hurting the corn crop. This year, corn plantings have been severely impacted by the heavy rains and cold weather, so that decisions on crop plantings have become more complicated and delayed, with follow-on impacts on the ultimate yield in a number of Midwestern states. Corn yield apparently falls at an average rate of 2.3 bushels per acre per day of delay in northern Wisconsin. These changing conditions make it difficult to assess how much ethanol, for example, will be available to meet demand, although the latest EIA TWIP holds out some optimism for this year.

The impact of the drought on corn prices, and the consequent fall in ethanol production, as production costs rose, are directly visible from their plot of the two over the last year.

Figure 1. A comparison of corn prices and ethanol production in the USA (EIA TWIP )However, with the weather impacts still being assessed, it is already being concluded that the US corn crop is unlikely to reach the record level of close to 14.6 billion bushels that were earlier projected. It still, however, has the potential to reach around 12.3 billion bushels, which would satisfy the just under 5 billion bushel need for ethanol, as well as other demands of the market. By May 12 only 28% of this year’s expected crop had been planted, in contrast with a normal year where 65% would be in the ground. Thus, even the relatively short-term projections of the EIA could yet be in trouble for this year.

Moving to the slightly longer-term, the nations that form OPEC must try to estimate global demand for their products and the amount that other non-OPEC nations will produce, so that they can balance supply and demand at such a level that will sustain prices they are comfortable with. Their estimates come out as Monthly Oil Market Reports and in the latest (May) version they continue to expect global demand to increase by 0.8 mbd over 2013, but are beginning to hedge that bet as the global economy continues to appear anemic, with Russian and Asian economies slowing. Yet by the fourth quarter of the year, they anticipate that global demand will reach 90.9 mbd.

Figure 2. Global oil demand by region (OPEC MOMR)OPEC anticipates that with the major increase coming from the Americas, that non-OPEC oil production will increase by just under 1 mbd to reach an a level of 54.41 mbd in the fourth quarter of the year. The majority of that growth (some 0.59 mbd) will come from the United States, with the Permian, Bakken and Eagle Ford being cited as the anticipated source of these gains. OPEC, having looked at current rig counts, project that these numbers may be revised upwards over the course of the year. And yet it is worth noting this:

On a quarterly basis, US oil supply is seen to average 10.62 mb/d, 10.67 mb/d, 10.62 mb/d and 10.61 mb/d respectively.

The sustained gain in North American production comes about because:

On a quarterly basis, Canada’s production is anticipated to average 4.02mb/d, 3.97 mb/d, 4.02 mb/d and 4.12 mb/d respectively.

Russia is expected to continue to lead in oil production over the course of the year, although it is not longer expected to increase production above current levels.

On a quarterly basis, Russian oil supply is seen to average 10.45 mb/d, 10.43 mb/d, 10.43 mb/d and 10.43 mb/d respectively.

And this brings us back around to OPEC as they try and balance their production against the gap between global demand and non-OPEC supply. As has been the case for a while, OPEC produced two separate tables showing production, as reported by secondary sources as well as those directly reported by the countries themselves.

Figure 3. OPEC member production as reported by secondary sources (OPEC MOMR)
Figure 4. OPEC member production as reported directly (OPEC MOMR)It would appear with Manifa coming on line, that Saudi Arabia is increasing production again, while Venezuela and Iran would have you believe they are producing more than they are, and Iraq, which is now producing above 3 mbd, is directly reporting less (though that could be because some of that production is coming from the north, and there are some communication problems between there and Baghdad).

As long as OPEC has available reserves, it can continue this balance to keep enough oil available at an acceptable price to allow the world economy to continue at its present pace. And with that ongoing adjustment available, their projections for this year of a relatively stable price would seem fairly founded, absent some major change in one of the larger producing states.

Iraq overtook Iran as the second largest producer in OPEC last year (according to secondary sources) and expects that with production from Majnoon, it will increase production capability by upwards of 200 kbd by the end of the year. Ultimately the goal is to achieve a target production of 1.8 mbd. However, as overall production levels increase, Iraq may join with the Kingdom in controlling production to maintain price.

Yet even with those abilities, OPEC is becoming cautious about predicting that their estimate of the demand:supply balance numbers for this year will be accurate over that time interval.

With these uncertainties in even short-term projections of future production, whether it be corn, ethanol or crude, it is perhaps wise to continue a somewhat cynical view of projections over a longer time period. Although the bounding bar of a decline in existing field production continues to exist, and will continue to require an offset in increased production from new wells to offset. Perhaps that lady in the tent of my youth may prove as prescient as some of the more optimistic forecasts that we continue to see.

And when the corn belt dries up from climate change…then what?

Oooh! Good luck with all that, eh?

Could we not make things a little ‘simpler,’ instead of adding layers of un-necessary complexity to the unmanageable pile we’ve already built up? With all the “unintended consequences” th

The corn to ethanol for fuel is a giant con game.

..that implies. People(s) are are really going to have to get together in some as yet un-tested way in order to prolong the presence of our species on this planet. Lots of things are actually happening (though on rather small scales) around the world. Whether or not critical mass can be reached before it’s “too late,” whatever that might mean, we just don’t know. What we do know is that, even with a miraculously concerted international effort to “save the planet,” no positive outcome is guaranteed for our species (and many others). In spite of all that, I still think a difference can be made as to the ferocity of how the winding-down of our industrial/fossil fuel orgy plays out. Is it just a question of softening and delaying the inevitable? Quite possibly. But even that would be better than nothing, wouldn’t it?

It might be saved if there weren’t so many that believe that we are in the ‘last days’ and that they will be saved and go to the ‘Garden of Eden’ in some distant dimension, and they won’t suffer, so they don’t care what happens to the earth.
