I thought Robert over at TOD had already thoroughly discredited the HL nonsense?

Why not take a stroll over there with your buddy "abundance" and find out?

But now you dismiss a simple algebraic tool, a model that illuminates Hubbert's methods quite reasonably (designed and tested by another Shell geologist) and shown to be an accurate facimile of Hubbert's complex calculus. As nonsense?

So what explains the resistance to THAI in some quarters?
Young entrepreneurs have no problem talking about it. But there's a bunch of guys - and I'm guilty of this - who tend to colour their thinking with their own history. THAI uses fire-flooding, which has been done for ages, a lot of it unsuccessfully and sometimes catastrophically - people have been killed in Venezuela, for example. So the thinking is: "If it's fire flooding, I'm not going to get deep into it. I won't try to understand how good it is or how different this particular technology is." And some people are just resistant to change.
How much capital is tied up in THAI?
It's probably less than 10 per cent of our total corporate investment. In terms of all-in costs, Whitesands [the oil sands property that is testing THAI] has cost less than what we spent on each of PetroBakken and Petrominerales just last year. So it is a small investment but the payoff on that lottery ticket is big. We will start making money this year on 11 wells in Saskatchewan.
Petrobank is working on toe-to-heel air injection (THAI), a process using underground combustion to achieved higher heavy-oil recovery rates with a lower environmental footprint. But Petrobank has been dogged by production glitches at its test site that have delayed development. With the technology facing both fans and detractors, Mr. Wright argues that THAI is in the home stretch to commercial use.
Back to THAI: Why should I believe this will work?
The coolest thing I can show you is at our Conklin project in the oil sands, where you go to the injection wells and just hear the air going in. Then you walk 800 metres to the production wells and you can hear the oil coming out. Air is going in and oil is coming out; it is that simple.
SharePetrobank Energy and Resources is buying out its partners in two joint ventures that are to use its innovative fireflood heavy oil recovery technology (Toe-to-heel air injection - THAI). If THAI is fully successful it could increase oil recovery from the oilsands to 80% of oil in place.

Petrobank is to reveal details of its strategy to make THAI work in early 2014.
The company’s patents for the one-well injector, one-well producer setup expire in 2015, which means anyone can use the technology at that time, Cheung said. He added patents on other combustion-based configurations discovered over the past seven years are in force well into the 2020s.
Petrobank shares closed 3.5 cents higher at 36.5 cents on the Toronto Stock Exchange. It started 2013 at $1.19 after distributing its shares in PetroBakken Energy Ltd. (now renamed Lightstream Resources Ltd.) to its shareholders.
In a note to investors, analyst Mike Dembicki of TD Securities said the deadline for THAI is welcome.
“Looking at the recent share price performance, we believe that the market has largely discounted the THAI process,” he wrote.
“We view the change in corporate strategy focus to stopping negative cash flow operations and potentially using conventional thermal techniques as positive.”
