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.
Process engineers are found in almost all industrial plants, and they are responsible for the design, operation, control and optimization of chemical processes. They examine how raw materials are converted into useable productions and how to improve the process. Process engineers in the oil and gas industry are usually focused on the downstream portion including chemical plants and refineries, however their knowledge can be useful in manufacturing plants as well as in upstream and midstream operations. Due to the extensive knowledge of chemical processes that these positions require, process engineers usually hold chemical engineering degrees.
