Shale Gas: Promises, Promises, Promises

Arthur Berman could be very wrong. His points have been debated for years among those in the shale gas business. They are NOT revelations to anyone who is connected to shale gas and generally are not considered anything more than FUD. I've sat through many late night debates about all of these issues long before Berman ever voiced them.

The first thing Berman does wrong is typical of some engineers. He thinks "average wells" exist. CHK, DVN, and XTO all own very different acreage in the play, have different completion practices and histories, and even have different cost structures. Berman is averaging in the early wells that failed, the vertical wells with the horizontals, the wells in all types of geologic areas, and for every size and skill set of operator. Not even conventional plays will hold up to this type of "average well" analysis. Its a classic over-simplified engineering approach that can kill any new play. Core areas have very different production than the play overall. Berman ignores this.

"The gas companies are assuming a hyperbolic decline curve based on a very limited data set from a few wells, while Dr. Berman found, after studying far more wells.." This is nonsense. These operators have access to FAR MORE DATA than Berman can ever hope to see. Berman is restricted to the data in the public domain, which is reported to the Texas Railroad Commission according to their reporting requirements (which actually cause biases in the data). He can't possibly have BETTER data. That said, I agree that hyperbolic decline curves do overestimate EURs but the same is true for conventional reserves. Hyperbolic curves tend to reflect best case.

Berman's whole approach is flawed because he builds the worst results of the earliest learning curve (which in the Barnett was THE EARLY learning curve) in with later results. By combining these he is assuming that no one improves with experience, and that no operator is better than average.

Profitability is certainly a concern with lower gas prices. That is also true of the conventional Gulf of Mexico (especially deepwater) and all LNG. At some point no natural gas production makes money (yet supply may continue). Reductions in cost of drilling alone can dramatically change the economic potential of a well. At least one study by Drilling Info, Inc. found "there is a 80 to 100x differential in play reserves between static D,C& S costs and $7/mcfg...and $2.50/mcfg." Wellhead cost is not a valid way to address full cycle economics.

"Shale gas companies are funding drilling with debt and asset sales" is probably the one statement Berman makes that I am seriously concerned about. Some companies are clearly doing this, and others are benefiting from the "hype" surrounding their early success in these plays. Then again, isn't that the way the business works for anyone other than the Seven Sisters? It could easily be argued that those who are funding themselves this way are the best businesses, since in the long run they hope to leverage their way into larger and larger market share. That may have been the most effective way to deal with the downturn in 2008. In a rising commodity price market, they will reap the benefits. In a falling market, they seem to have buffered themselves. I think Berman's concern about this may have some validity, but is far too simplistic- again. I have a hard time believing that every operator drilling gas shale wells is doing it at a loss.

Take Berman with a grain of salt. His bias seems to be against all unconventional oil and gas, which I tend to believe is due to resistance to the geologic and engineering paradigm shift that has made gas shale possible. Likewise, he makes more money being controversial than being mundane.

Shale Gas: Promises, Promises, Promises

Yes, you can use the natural gas supplied to your home as auto fuel. You will be legally exempt from paying fuel taxes that are added to the cost of gasoline since natural gas is exempt. That savings alone is significant. You can buy a compressor unit that will allow you to fuel your car at home. As with most alternatives, it is barely economic for most people, but there is a savings in fuel cost (mostly due to taxes), improvements in engine wear (my opinion), improvements in carbon output, and you may be allowed to use the carpool lanes in some places, saving more fuel.

Book Review: Robert Hefner's 'The Grand Energy Transition'

Natural gas is currently suffering from being categorized along with oil by policy makers and consumers. The two fuels vary dramatically in supply, marketing, and consequences of consumption. We do have a hundred year supply of natural gas, even if consumption rises, due to changes in drilling technology and geologic paradigm shifts that are currently being adapted in the natural gas industry.

Currently natural gas is the only fuel that can be used to quickly supply electric power when demand rises unexpectedly. Wind power, solar, nuclear, hydroelectric, and even coal cannot do that as quickly as natural gas. Currently natural gas is the cheapest source of hydrogen. In effect, burning natural gas IS burning hydrogen as most of the energy comes from the 4 hydrogen bonds.

There is no reason that natural gas cannot be used to substitute for transportation fuel (gasoline and diesel), yet wind and solar cannot do that with any efficiency. I converted my vehicle to natural gas in 1974. Large fleets of buses and garbage trucks in my area have been converted for years.

The real problem for natural gas is that the current administration is throwing the baby out with the bath water, by limiting natural gas production and doing nothing to improve natural gas distribution systems. Currently the natural gas industry is facing higher taxes, serious restrictions on technology applications, revocation of Federal leases, increasing royalties and severance taxes at both federal and state levels, and a supply glut that is forcing most producers to stop drilling and cancel programs that would have been our supply several years from now. Boom and bust, while decried by Obama, seems to be the real result of his administrations policies for the natural gas industry. Maybe Al Gore (who was once a proponent of natural gas) needs to read this book so that maybe the Whitehouse will get the message.
