Boasting 178 billion barrels of proven oil reserves and close to 58 Tcf of proven natural gas reserves as of 2009, Canada is the world's largest reserve holder after Saudi Arabia and the top supplier of U.S. energy imports. Canada is also home to the world's most expansive oil sands deposits, the development of which extracts and processes a heavy, tar-like crude bitumen that comprises the bulk of the country's reserves. Canada's oil and natural gas sector is privatized, with industry regulation occurring at the provincial level.
Geoscientist is a general term used to describe the individuals responsible for locating, evaluating and developing oil and gas reservoirs. Geoscience professionals use technology and applied science to maximize the recovery of oil and gas. They are present at all phases of the reservoir life cycle, from exploration, through drilling, production and eventually abandonment. They will measure and map seismic, magnetic, and other earth forces that affect the earth, as well as study and interpret data that is useful in locating oil and gas reservoirs. Geochemists, geologists, geophysicists, as well as geoscience technicians all fall into this category.
