The oil and gas industry is usually divided into three major sectors: upstream (also called exploration and production or E&P), midstream and downstream. [1] [2] 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 ...
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. Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical ...
Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. [1] Exploration and production are deemed to fall within the upstream sector of the oil and gas industry.

DOGGR – Division of Oil, Gas, and Geothermal Resources (former name of California's regulatory entity for oil, gas, and geothermal production) DOPH – drilled-out plugged hole; DOWRE – downhole report; DP – drill pipe; DP – dynamic positioning; DPDV – dynamically positioned drilling vessel; DPL – dual propagation log
The oil and gas industry is usually divided into three major components: upstream, midstream and downstream. The midstream sector involves the transportation (by pipeline , rail, barge, oil tanker or truck), storage, and wholesale marketing of crude or refined petroleum products.
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.
The upstream side of the industry tends to be the most sensitive to changes in oil and gas prices. With oil prices near the lowest level in a year, even top E&Ps like ConocoPhillips (NYSE: COP ...
