The Future of Natural Gas
This is so broad a subject I hesitate to even try to
fit it into one discussion. In my work I do a lot of research on natural gas. I
don’t think any commodity is so widely talked about while being so woefully misunderstood.
Lack of knowledge regarding industry operations combined with PR campaigns from
gas industry and environmental groups have led to a mass of misinformation.
This has culminated in the following beliefs:
- New technologies have unlocked 100 years of domestic natural gas reserves
- Advanced techniques now allow more gas to be produced with fewer rigs and resources
- Because of the value of liquids being drilled for, “associated” (byproduct) natural gas can be profitable regardless of the price
- Because of the above two bullets, natural gas production will only increase
- Because of increased production, natural gas consumption can increase drastically while keeping the price within the $2-4/Mcf range
Regrettably, none of these claims are true. The
amount of information that could be included here is immense. To try to avoid
obfuscating the issue with excessive detail, I will try to keep it limited to
main points.
Supply
Anyone who follows the energy markets has heard the
claim: 100 years of clean energy. That sounds pretty great. Even if we doubled
our natural gas consumption then we would have 50 years of supply – more than
enough time to research alternative fuel sources. Unfortunately, the claim is
outdated. The U.S. Geological Survey decreased their estimates to 20 years of
marketable supply in August of last year. The issue? Marketable supply.
Geologist Art Berman has been spearheading this
issue for some time. Shale reserves are vastly overstated for two reasons.
First, the production from shale wells decreases 30-50% after the first year of
production. In short, companies must constantly drill in order to maintain
supply. Second, the reserves included in the original 100 year total are not
economically viable to drill. That is, they are not concentrated enough to
warrant the cost to extract the gas. Art’s graph of Barnett drilling highlights
how concentrated the marketable reserves really are:
Priced into the market is the assumption that gas
reserves are higher than they actually are and companies are making long-term
decisions based on those beliefs. Yet at the same time, gas rig counts are
constantly decreasing. The following shows rig data from Baker Hughes:
While associated gas from oil drilling has propped
up natural gas production, it is not sufficient on its own. It is still a
byproduct of the activity and is often flared. Low price has led to the
decrease in gas rigs and the decrease in dedicated natural gas rigs appears to
finally be decreasing withdrawals. We will discuss later why it has taken so
long to do so.
Demand
Natural gas demand has been increasing drastically
in the past few years, mostly in the domestic energy sector. The cheap price
combined with an efficiency factor over coal generation has led to this being
the most cost efficient fuel source. This is occurring at the same time when
coal is getting hit with EPA regulations (CSAPR, MATS, CCS mandates on new
plants, etc.) Installing the controls is extremely capital intensive ($500M+),
which effectively regulates plants of <200MW out of existence. In addition,
running the controls has a parasitic load estimated between 5-15% of the
overall plant generation, which increases the cost.
Plants have to make long-term decisions at a time
when environmental regulations are negatively impacting coal, natural gas
prices are historically low, and the analysis by every energy firm is that
those prices will stay that way. So given a weak electric market when these
utilities are choosing which plants to run, which plants to close, and what new
plants to build – natural gas has been their choice.
And while they have yet to make an impact on the
market, there are several other opportunities for natural gas consumption. The
price premium of international LNG over domestic natural gas prices makes LNG
export very attractive if new terminals can get permits. Likewise, CNG and LNG
vehicles are slowly gaining traction because of the low cost of natural gas
relative to diesel. Clean Energy and other companies are working on natural gas
trucking corridors to increase the possibility of conversion. The following
from a natural gas convention in October of 2011 shows a summary of projected
demand increases by 2020.
All of this paints a very rosy picture for the
natural gas industry. But as any economist knows: the market always corrects.
What is positive for demand is undoubtedly also positive for price.
Prices
& Profitability
With supply likely stagnating because of the factors
mentioned in the first section, increased demand will shift the equilibrium
price. It has been estimated that a 2 Bcf/day increase in gas demand equates to
a $2/Mcf price increase. Based on the gas industry’s projection above, that
would theoretically increase natural gas to a minimum of $10.70/Mcf by 2020.
This is a far cry from the $4.50 that is being projected by CERA and others.
And in reality, supply has the very real possibility
of not just stagnating but decreasing. Despite claims to the contrary by
natural gas companies, natural gas needs to be somewhere between the $5.50-9.00/Mcf
range for drilling to be profitable. Encana, Chesapeake, and others have been
forced to announce cutbacks because of the low gas price and associated gas
simply cannot fill the void in the long-term. The graph below shows how this is
already starting to occur.
The graph below highlights how volatile gas has been
within the last decade.
Bottom line: with demand increasing and
supply at best remaining constant, price will increase. As it has throughout
history, once enough conversion has taken place the price will spike
drastically.
Other
Miscellaneous Factors
The question that seems to have confused people and
led them to agree with analysts who ostensibly have knowledge of the industry
is this: “Why so long? Gas prices have been below marginal costs for some time.
Why now? If prices haven’t already shifted, why would they do so now?” In
addition to the reasons listed above, there are some mitigating factors that
have gone into this.
The first is that new natural gas supply has
outstripped pipeline capacity. As old pipeline routes have become obsolete due
to new shale resources, the pipeline industry has not been building new
pipelines as quickly as drilling companies have drilled new wells. This has
created a massive supply glut with no outlet to utilities and other customers
who would potentially buy the gas.
This supply glut combined with an unusually warm
winter has created stored gas levels that have never been seen before. Storage
capacity will likely fill up this summer – forcing drilled gas to either
be capped or flared. This excess of stored gas creates excessive supply even as
drilling and production decrease.
Then we must look at the drillers themselves. Savvy
companies were able to take advantage of long-term price hedges. This enabled
them to get a relatively premium price for their gas even as the market price
was collapsing. These favorable hedges have now either expired or are soon
expiring. Those same companies also had lease agreements that mandated that
they drill with no consideration to price. Again, those old lease agreements
are expiring and companies are not entering into new ones (read: decreased
production).
Conclusion
The combined effect of this is fairly clear. Demand
has and will continue to increase. If historic well depletion rates hold true
and rig counts continue on their current path, supply will at best remain
constant. And mitigating factors that have kept production and storage levels
high are slowly going away. This will lead to further decreases in drilling until
the inevitable happens when gas price goes back up and drilling becomes
profitable again.
Might this take several years? Absolutely. But
projections of a slow, incredibly stable increase in gas price for the 30 next
years when it has been nothing but unstable in the past are patently absurd.
