We've been consulting some professors ourselves, more of which soon but in an interview with Energy Tribune, their expert is Roberto Aguilera and lets see if we can take him at least as seriously as the average UK energy consultant who wants the customer to sign up to fixed price.
Aguilera was educated at the University of America in Bogota, Colombia in petroleum engineering (1963-1967) and the Colorado School of Mines where he received M.Eng (1971) and Ph.D (1976) degrees in petroleum engineering.
He is now a professor in the Schulich School of Engineering, chemical and petroleum engineering deparment at the University of Calgary, where he holds the ConocoPhillips-NSERC-AERI Chair in Tight Gas Engineering. He is also a Director of Junex in Quebec and Chairman of the editorial review board of the Journal of Canadian Petroleum technology.
OK, he should know his stuff. So what is his opinion about the world wide potential for shale?
global tight gas reserves are likely equal to those of conventional gas reserves
That was July last year. Has he changed his mind?
...by using creativity the industry is finding keys to unlock the North American unconventional natural gas endowment which is, simply put, gigantic.
ET: Will this revolution mean lower gas prices over the long term?
RA: As long as the gas bubble remains the prices will be low. It is a matter of supply and demand. However, the fact that there is a very large gas endowment could lead to creative means of increasing the utilization of this resource in such a way that will benefit everybody: The US and Canada as a whole, the companies involved in the production and delivery of gas and the consumer.
ET: Speaking of prices, what is a sustainable price for natural gas? I ask because I’ve heard some producers insist that shale gas wouldn’t be profitable when prices are under $8. Now, I’m hearing $5. What’s your take on the relationship between the relatively high cost of drilling for tight gas and the market price which has been so volatile lately?
RA: My take is that $5 to $6 will work in most cases and will make most shale plays competitive.
$5-6 is 31.4/37.6 pence per therm by the way. Marginally higher than today's price, far lower than the $14 during summer 2008. But, let's go back to the key question: Is there shale gas elsewhere?
... tight gas reservoirs are present in almost all petroleum provinces around the world. The same holds true for shales -- more so because shales are a very important source rock. So my vision of several Barnetts around the world stems from the pervasive presence of shales. Black shales of South America and Africa are similar to those of North America in their association with sandstone and siltstone. Black shales of central Europe and the western part of the former Soviet Union are associated with carbonate reefs, an association that as far as I know is not present in North America.
Several Barnetts around the world? That should change energy economics almost everywhere, one example beng as Reuters reports, the Arctic
The energy industry's decades-long dream of tapping vast Alaskan and northern Canadian gas reserves faces perhaps its biggest threat yet -- a flood of new unconventional supply located closer to markets.
Now, industry experts wonder if rapid development of gas trapped in shale formations throughout the United States and Canada could render Alaska and Northwest Territories pipelines obsolete even before any steel is put into the ground.
But bizarrely, the push in Europe is to build an equally large grand project: The Nabucco Pipeline aims to reduce the risk of Russian gas getting caught up in another Ukraine argument by simply building a 4000km detour so we can get gas from more stable sources: Azerbaijan, Turkmenistan and Iran for example. And instead of unreliable Ukraine we can transit the gas through areas famed for stability and good governance: Armenia and Kurdistan to name but two.
Even more bizarrely two key players in Nabucco are Hungarian MOL and Austrian OMV, both among the few EU gas producers to investigate the potential of their own Barnett sized Carpathian shale as Aguilera pointed out above.
The Reuters story should be resonating in Europe. Why not?
The amount of gas that's been found over the last 24 months was clearly inconceivable to forecast five years ago," said Manuj Nikhanj, vice-president of Ross Smith Energy Group, a Calgary-based institutional research firm.
"So at no fault of people's thinking five years ago, there's been a huge paradigm shift with respect to the natural gas market, and really it just comes down to a cost analysis."
