Blue,
Think of THAI like a diesel engine.
You need pressure, fuel, and air
Underground is lots of pressure and in PBG land bitumen/oil. Then you inject air into this place where lots of pressure and bitumen reside - you get an explosion and start a fire. You want this to stop? - turn off the air, no air can't burn - reaction will smother itself
With regards to direction of fire front, the way I understand it is that the horizontal production well creates negative pressure in the reservoir, the idea then is the fire front which is pushed by the injected air is coming from will tend to move from high pressure toward the lower pressure part of the reservoir.
They also have multiple sensor wells that will record and track the intensity, direction, and speed of the fire front.
Of course, as someone else noted, you should get acquainted with PBG, THAI, and all their assets BEFORE you invest. Their IR is helpful and their presentations give a fairly good idea of how the technology works without getting into too much of the science.
It is a wonderful technology, if it works, not only for investors but for the environment - lots less CO2, minimal NG use, allows more ground to be economical to extract, less cap ex, lots less water used, and even partially upgrades the bitumen. |
