Yesterday, our oil sands tour took us an hour south of Fort McMurray to ConocoPhillips' (COP) Surmont facility where we viewed the oil extraction process called steam assisted gravity drainage, or SAGD. The bitumen, or oil and sand mixture, is well below ground at this site. To give you an idea on how deep it's buried, you'd have to take an elevator 90 floors beneath the earth to get to it. The bitumen in its virgin state is very hard--like a chunk of honey. Our Canadian guides like to compare it to a hockey puck.
The SAGD process uses steam to soften the bitumen underground so that it can be extracted, processed and transported through a pipeline for further processing. Two parallel wells are drilled on each well pad: One for steam injection to heat the bitumen-rich sand, and another run... more »
