THAI sounds a bit like something out of a science fiction novel. It involves drilling a hole into the oil sands, injecting oxygen and igniting a continuous underground burn or "fireflood." Over the course of several months, that fireflood slowly works its way through the oil sands reservoir, heating up the bitumen so it drains into a horizontal collector well. No digging. No huge mining equipment. Just a few pipes, some wellheads and a modest processing facility.
THAI is still considered experimental by the oil sands industry, but Petrobank is so confident that it works, it’s forging ahead with two commercial-scale projects using THAI.
