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 ...
The oil and gas industry is usually divided into three major sectors: upstream, midstream, and downstream. The downstream sector is the refining of petroleum crude oil and the processing and purifying of raw natural gas, [1] as well as the marketing and distribution of products derived from crude oil and natural gas.
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.
Vertical integration is the degree to which a firm owns its upstream suppliers and its downstream buyers. The differences depend on where the firm is placed in the order of the supply chain. There are three varieties of vertical integration: backward (upstream) vertical integration, forward (downstream) vertical integration, and balanced (both ...
This speed differs from the speed of sound in the gas by the velocity at which the gas is moving in the pipe. The other paths may be identical or similar, except that the sound pulses travel downstream. The meter then compares the difference between the upstream and downstream speeds to calculate the velocity of gas flow.
It can be divided into two directions: upstream and downstream. Producers or commercial retailers can have a supply relationship with upstream suppliers, including manufacturers, and form a sales relationship. [6] As an example, Dell works with upstream suppliers of integrated circuit microchips and computer printed circuit boards (PCBs).
There are a variety of supply-chain models, which address both the upstream and downstream elements of supply-chain management (SCM). The SCOR ( Supply-Chain Operations Reference ) model, developed by a consortium of industry and the non-profit Supply Chain Council (now part of APICS ) became the cross-industry de facto standard defining the ...
