The oil industry is a massive, multi-faceted environment that spans a number of different processes and occupations. As the industry is so complex and encompasses so much, it is divided into three distinct sections based on the steps from drilling to refinement. The three distinct sector of the oil industry are: Upstream, Midstream, and Downstream. The upstream oil sector is also referred as the exploration and production (E&P) sector.

The upstream sector includes the searching for potential underground or underwater crude oil and natural gas fields, drilling of exploratory wells and subsequently drilling and operating the wells that recover and bring the crude oil and/or raw natural gas to the surface.
