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.
Petroleum engineers handle many responsibilities, but on a basic level they are responsible for locating, recovering and maintaining the world’s oil and gas supplies. Petroleum engineers design and develop methods for extracting oil and gas from below the earth’s surface. Their duties can also include managing an oil or gas producing property once it is operational and maximizing the performance and profitability of a well. Petroleum engineers are involved in all stages of well production, from helping to locate a potential well site, through drilling, production, processing and transportation. Some job titles a petroleum engineer may carry include reservoir engineer, drilling engineer or production engineer.
