Upstream vs. Downstream Oil & Gas Operations: What's the Difference?

They must know the working cycle of the industry and the responsibilities of the different sectors involved in the process. The oil and gas industry is one of the largest industrial sectors in the world in terms of generating value in dollars. This is also known as the petroleum industry. This industry is very crucial to the global economic framework especially for countries like the United States, Saudi Arabia, Russia, Canada, and China. Petroleum is important to many industries and is necessary for the operating and maintenance of Industrial plants, machines, and transportation purposes.

Overview of Oil and Gas Industry: Upstream, Midstream, Downstream

Light and sweet crude oil is usually priced higher, and therefore more sought-after, because it is easier to refine to make gasoline than heavy and sour crude oil. Natural gas is found in both associated formations, meaning it is formed and produced with oil, and non-associated reservoirs. Gas can either be dry pure methane , or wet exists with other hydrocarbons like butane. Although wet gas must be treated to remove the other hydrocarbons and other condensates before it can be transported, it can increase producers' revenues because they can sell those removed products. Oil and gas exploration encompasses the processes and methods involved in locating potential sites for oil and gas drilling and extraction. Early oil and gas explorers relied upon surface signs like natural oil seeps, but developments in science and technology have made oil and gas exploration more efficient. Geological surveys are conducted using various means from testing subsoil for onshore exploration to using seismic imaging for offshore exploration.


The term 'upstream' also includes the steps involved in the actual drilling and bringing oil and natural gas resources to the surface, referred to.


Industry Overview

This section covers researching past and present oil and gas companies, resources for starting a company in the oil and gas industries, and references to top companies. The oil and gas industry is frequently divided into three segments: upstream, midstream and downstream. While each of these areas has a number of independent companies, major companies in oil and gas are often considered integrated , meaning their businesses consist of a mix of upstream, midstream and downstream activities. Companies can be private, public, or state-owned, which impacts the amount of information available.

Introduction to Oil and Gas Industry

Considered being the biggest sector in the world in terms of dollar value, the oil and gas sector is a global powerhouse using hundreds of thousands of workers worldwide and generating hundreds of billions of dollars globally each year. In regions which house the major NOCs, these oil and gas companies are so vital they often contribute a significant amount towards national GDP.

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 downstream sector reaches consumers through products such as gasoline or petrol , kerosene , jet fuel , diesel oil , heating oil , fuel oils , lubricants , waxes , asphalt , natural gas , and liquefied petroleum gas LPG as well as hundreds of petrochemicals. Midstream operations are often included in the downstream category and are considered to be a part of the downstream sector. Crude oil is a mixture of many varieties of hydrocarbons and most usually have many sulfur-containing compounds.

Он был зашифрован с помощью некоего нового алгоритма, с которым фильтры еще не сталкивались. Джаббе потребовалось почти шесть часов, чтобы их настроить. Бринкерхофф выглядел растерянным. - Стратмор был вне. Он заставил Джаббу вмонтировать в ТРАНСТЕКСТ переключатель системы Сквозь строй, чтобы отключить фильтры в случае, если такое повторится.

Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.  - Скажем, принести пару таблеток валиума. Наконец канадец опомнился.
