Albertans have always known that in the northern part of their province, there are vast deposits of bitumen--black, tarlike goo that is mixed with sand, clay, water and oil. GLJ's development profile of Grizzly Oil Sands ULC is a private, Calgary-based oil sands exploration and production company focusing primarily on the development of oil sands resources using thermal recovery methods. The prize Royal Dutch is chasing is The firm is trying to commercialize what it calls a "novel thermal recovery process" invented by Shell's technology arm. The company, through a secretive Calgary-based subsidiary called Sure Northern Energy Ltd., is working to unlock an estimated 60 billion barrels of raw bitumen — more than 100 kilometres west of the oil sands epicentre around Fort McMurray in northeastern Alberta. The candidate should have managed several different aspects of heavy oil/bitumen production, including strategic planning, prospect generation, operations, and thermal recovery development. As they note the trade off the thermal inertia of the oceans. Laricina Energy points out in a presentation, Strategies for Cheaper Bitumen, the rate of oil recovery is a function of the (time averaged) reservoir temperature and that the optimal recovery temperature is in the range of 150oC. Shell, for instance, is working on a "novel thermal recovery process"--embedding large electric heaters in the deposits and literally cooking the earth. It will take a millennium to bring the atmosphere, the shallow waters and deeper ocean waters into thermal equilibrium on account of all of the energy the oceans have already stored. There are approximately 2.5 trillion barrels of the stuff, the largest on figuring out how to get the dirtiest possible oil out of the hardest-to-reach places. GLJ identified 1.8 billion barrels of exploitable bitumen in place and has assigned 824 million barrels of contingent resource as a best estimate using steam assisted gravity drainage and Grizzly's ARMS development model.
