Offshore is part of the upstream sector of the oil and gas industry. [1] Offshore activities include searching for potential underground crude oil and natural gas reservoirs and accumulations, the drilling of exploratory wells, and subsequently drilling and operating the wells that recover and bring the crude oil and/or natural gas to the surface.
