Recently, I had the unique opportunity to tour two different oil sands operations near Fort McMurray, in northern Alberta. I saw a massive open-pit oil sands mine, and the associated reclamation effort, operated by Syncrude Canada Ltd. I also visited an in situ oil sands recovery project called Surmont, operated by ConocoPhillips (NYSE:COP).

When most people think of oil, they think of light, sweet crude that comes up out of little holes in the ground. You describe oil by its API gravity. For example, oil like Brent crude or West Texas Intermediate has an API gravity of 38-40. The oil that Col. Drake pulled from the ground at Titusville, Pa., in 1859 had API gravity near 60. These types of oil are relatively easy to pump from a reservoir, lift to the surface and transport via pipeline to the refinery.
