Document Summary
Oil has been pulled out of alberta since 1914. Ways to get oil out of oil sands. One injects steam into the reservoir that then becomes pressurized. Two wells mean twice the expense of drilling. 80% is too deep to open pit mine. Less sediment coming up that you have to deal with. Push to recycle the water used, and use salt water. No one wants the salt water, in deeper reservoirs. Salt water is hard on the equipment. 2 tonnes of oil sands produce one barrel of oil. 3-5 barrels of water are needed for one barrel of oil. Extremely low price for large quantities of water. The alberta government sets the low price, also are the people that get royalties from the oil sand profits because they leased out the land. Steeled tailings have high water content and can"t support weight. Noise making cannons used to deter birds from landing in tailing ponds.
