Water-based extraction process (WBEP) has been successfully applied to bitumen recovery from Athabasca oil sand ore deposits in Alberta. In this process, two essential steps are involved. The bitumen first needs to be "liberated" from sand grains, followed by "aeration" with air bubbles. Bitumen "liberation" from the sand grains is ...

Most of Alberta's operating in-situ facilities currently extract bitumen from a depth of at least 300 meters. The bitumen recovery process is quite different for mining versus in-situ facilities. Mined oil sands requires large amounts of water to separate the bitumen from the sand, while the in-situ facilities require less water but greater ...

A 797 truck used in the extraction of oil sands for hauling the extracted sand. [1] Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing.

In 2021, about 40% of all bitumen from the oil sands was upgraded into synthetic crude. That amounted to 1.2 million bbl/day, from six bitumen upgraders— Syncrude's Mildred Lake, Suncor's U1/U2, CNRL's Horizon, the Scotford Upgrader (operated by Shell) and Sturgeon. Syncrude, Suncor, Scotford and Horizon process mined bitumen.

Oil sands are a naturally occurring mixture of bitumen (oil that is too heavy or thick to flow or be pumped without being diluted or heated), sand, clay or other minerals and water. Oil sands operators pay royalties on crude bitumen after the sand and other impurities have been removed. Crude bitumen is worth less than crude oil because bitumen ...
