The petroleum industry, also known as the oil industry or the oil patch, includes the global processes of exploration, extraction, refining, transportation, and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, synthetic fragrances, and plastics. The industry is usually divided into three major components: upstream, midstream, and downstream. Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products.
The oil and gas industry is usually divided into three major sectors: upstream, midstream and downstream. The upstream sector includes searching for potential underground or underwater crude oil and natural gas fields, drilling exploratory wells, and subsequently operating the wells that recover and bring the crude oil or raw natural gas to the surface.

Canada has the third largest oil reserves in the world and is the world's fourth largest oil producer and fourth largest oil exporter. In 2019 it produced an average of 750,000 cubic metres per day (4.7 Mbbl/d) of crude oil and equivalent. Of that amount, 64% was upgraded from unconventional oil sands, and the remainder light crude oil, heavy crude oil and natural-gas condensate. Most of the Canadian petroleum production is exported, approximately 600,000 cubic metres per day (3.8 Mbbl/d) in 2019, with 98% of the exports going to the United States. Canada is by far the largest single source of oil imports to the United States, providing 43% of US crude oil imports in 2015.
