Oil Sands

             Oil sands or bituminous sands, are a type of unconventional petroleum deposit.  Those natural deposits are reported in many countries such as: Kazakhstan, Rusia and Canada.  Therefore, they are founded in extremely large quantities in Alberta.  Total oil sand reserves are estimated at 249.67 billion barrels globally  and 70% are in Canada.  Alberta has been mining oil sands since 1967.  It is the most important financial support to the province. Conventional crude oil is normally extracted from the ground by drillinng. However,  the oil sands must be extracted by strip mining or the oil made to flow into wells by in-situ techniques. These processes can use more water and require larger amounts of energy than conventional oil extraction. That means it is a cotrovesial project because is very important  in the Canadian's economic but the other hand is too dirty with the enviroment.  That's why Oil sands  have had many people  for  and against them even though Oil's companies tries to make green strategies.  According to CAPP, Canadian Asociation Petroleum Producers, the industry understands Canadians' concerns and is working with new techniques and technologies to reduce our environmental impact. They are focus on three issues: air, water and land. Particularly in relation to air, since 1990 GHG (  Carbon dioxide-CO2 ) emissions   associated with every barrel of oil sands crude produced have been reduced by 29%. Also, Canada’s oil sands industry recycles water and continues to look for ways to reduce fresh water use.  Likewise, the industry  is committed to reducing its footprint, reclaiming all land affected by their operations.  In addition , Oil sands industry  is paid significant taxes and it is a major employer throughout North America. It seems challenges are coming up to Canada's Oil industry!
