In-Situ Bitumen Extraction | Oil Sands MagazineAbout 80% of Alberta's bitumen reserves are too deep to be mined and must be extracted in-place (or in-situ) using steamThe bitumen is heated and pumped out of the ground, leaving most of the solids behind In-situ extraction has a much smaller footprint than oil sands mining, uses less water and does not produce a tailings stream...

Role of Residual Bitumen on the Solvent Removal from ,Role of Residual Bitumen on the Solvent Removal from Alberta Oil Sands Gangue by , Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands The reduced dependence on fresh water and land for creation of tailing ponds...

Oil sands - WikipediaOil sands extraction can affect the land when the bitumen is initially mined, water resources by its requirement for large quantities of water during separation of the oil and sand, and the air due to the release of carbon dioxide and other emissions...

Oil Sands 101: Process Overview | Oil Sands MagazineBITUMEN EXTRACTION The Alberta oil sands hold an estimated 166 billion barrels of recoverable oil, representing over 96% of Canada's total reserv The method used to extract bitumen from the oil sands depends on the depth of the deposit If the deposit is near the surface, the oil sands ,...

Bitumen Extraction Explained | Oil Sands MagazineBitumen recovery is a critically important performance criteria for the Extraction plant Bitumen recovery rates within Extraction are normally quite high, typically in the 85 to 90% range However, recovery can be adversely affected by the quality of the mined oil sands ,...

Asphalt - WikipediaThe process used to extract the bitumen from the sand is a hot water process originally developed by Dr Karl Clark of the University of Alberta during the 1920s After extraction from the sand, the bitumen is fed into a bitumen upgrader which converts it into a light crude oil equivalent...

Oil Sands Geology & the Properties of Bitumen | Oil Sands ,Canada has the world's third largest oil reserves, mostly located in the oil sands Although oil sands and shale deposits are found all over the world, the Alberta oil sands are water-wet, making bitumen extraction feasible using just hot waterLearn more about this unique deposit and some of its chemical and physical properti...
