Petrobank still has to prove that THAI works in several different kinds of oil fields reliably and their recovery factor is as advertised. Many years ago underground fires were used but they tended to break thru to the surface and burn uncontrolled. That's why PBG has controlled air injection as part of their process. There are still plenty of hurdles but Petrobank has excellent mgmt and that is the key to execution over time. A few more qtrs like this one and they will actually deserve to be over $100!
Wish I had loaded up more when it was $9 or even $15 but it's still my biggest position and growing. This is fun! Bobwins
