Oil Sands Geology and the Properties of Bitumen | Oil

Oil Sands Geology And The Properties Of Bitumen | Oil

the athabasca basin is by far the largest, spanning an area of about 40,000 km². all mineable oil sands are located north of fort mcmurray, where the deposit can be found very close to the surface. the cold lake basin spans an area of about 22,000 km², extending into saskatchewan. the oil sands deposit is located 300 to 600 meters below the surface, making mining economically infeasible.,first results from the oil sands passive air monitoring,the athabasca oil sands region (aosr) in northern alberta, canada is the third largest bitumen deposit in the world, covering a mineable area about 4800 km 2. the oil industry in the area has been growing since mining activities started in 1967. in 2012, the production was quoted as 1.9 million barrels of crude oil

Risk Communication In Athabasca Oil Sands Tailings

essentially, tailings operations store the solids and water balance from oil sands mining operations. the oil sands (8–13% bitumen, ~60% silica sand, ~30% fine solids, and < 5% water) is transported in haul trucks from the open pit mine to the extraction facility where it is processed to extract the bitumen from the sand (devenny 2010). the bitumen is transported to the refinery for upgrading, and the tailings material—a slurry of water, sand…,facts about alberta’s oil sands and its industry,only 20 percent of alberta’s oil sands can be recovered through surface-mining techniques. if the oil sand layer is deeper than 75 metres from the surface, an in situ (in place) technology is used. steam assisted gravity drainage, or sagd, is the most common in situ process presently used. this process involves drilling two l-shaped
