All About Oil and Gas Industry

Natural gas and oil are major industries in the global energy market and represent the world’s primary fuel source. A significant amount of capital is spent on oil and gas production, distribution, and processing, as well as state-of-the-art technology.

Gas has traditionally been associated with oil, mainly because of the upstream aspect or production process. Because of shale gas development in the United States, natural gas has assumed a larger role in the world’s energy supply, and it emits fewer greenhouse gases when burned than oil and coal.

The oil and gas sector is the biggest industry in the world in terms of dollar value. Each year, this sector generates hundreds of billions of dollars around the world and employs numerous worldwide. Oil and gas companies are so vital to economies in regions with major NOCs that they often contribute a substantial amount to national GDP.

Oil and gas supply chain

A global supply chain for oil and gas involves many activities, such as visibility and control of orders and inventories, domestic and international transportation, import and export facilitation, materials handling, and information technology.

Large industries involve a sequential set of operations that involve multiple parties that are configured, managed, and improved continuously. In Supply Chain Management (SCM), the goal is to provide maximum service at a minimum cost to the customer.

Industries also need to have a high voltage vacuum contactor to prevent any electrical hazards.

What are the different sectors of oil and gas? 

Three main areas of the energy industry are upstream, midstream, and downstream.

  1. Upstream

In the upstream, we have E&P (exploration and production). Searching for natural gas and crude oil fields underwater and underground, drilling exploration wells, and existing wells to recover oil and gas are all included.

Upstream sector characteristics

In the upstream sector of the oil and gas supply chain, all activities revolve around wells, such as where to locate them, how deep to drill the wells, and how to design, build, and manage them.

Upstream businesses are characterized by the following four characteristics:

  • Carries high risk
  • Highly regulated, it is affected by global politics
  • Gives high return
  • Very technology and capital-intensive

There are stricter regulations regarding environmental regulations, production regulations, access to reserves, pricing, and taxation in this segment. In the initial exploration phase, it is a common occurrence for upstream activities to be very time-consuming and expensive.

The upstream segment includes the following sectors:

  • Offshore drilling
  • Supply and service
  • Oil sands mining
  • Manufacturing
  • Geological surveys
  • Seismic surveys
  • Reclamation
  1. Midstream

Gas and oil are transported, stored, and processed in the midstream. As soon as resources are recovered, they have to be transported to refineries, which are often in entirely different geographies from where the oil and gas reserves are. Tanker ships, pipelines, and trucking fleets are some of the means of transportation. 

In the oil and gas supply chain, midstream companies are those that operate between the upstream and downstream segments.

There are four main types of services that midstream companies provide:

  • Processing
  • Storing
  • Transporting
  • Marketing

The following are a few of the more specific services offered by the midstream industry:

  • Oil Field Services
  • Diversified Midstream Pipeline and Storage
  • Crude Oil, Storage of Excess, and Refined Products Pipeline
  • Natural Gas Gathering and Processing
  • Marine Shipping and Transportation
  • Natural Gas Pipeline and Storage

Midstream companies are known for their low capital risk and high regulatory standards, especially with respect to pipeline components. Another crucial factor to recognize is that midstream investments depend on upstream assets, and oil prices affect downstream participants’ demand.

  1. Downstream

During the downstream phase, raw materials obtained in the upstream phase are filtered. For example, crude oil is refined and natural gas is purified. Market and have access to these products through various distribution channels including natural gas, gasoline, lubricants, heating oil, diesel oil, petrol, kerosene, jet fuel, asphalt, and LPG (liquefied petroleum gas) as well as other petrochemicals.

The downstream sector’s main characteristics are: 

  • The business has high margins and high complexity
  • The global perspective should always be considered by companies
  • It includes marketing final products and delivering them to end-users and retailers.

Upstream is a margin business, defined as the difference between the price of oil products and the cost of delivering crude oil to a refinery.

As a result of including a wide range of activities, from refining to petrochemicals, from distribution to wholesale and retail marketing, this chain segment is quite complex.

Key downstream sectors include:

  • Oil Refining,
  • Supply and Trading,
  • Product Marketing- Retail and Wholesale

Different types of valves used

  1. Plug Valves

The plug valve is a cylindrical or conical valve body that can rotate inside the body to start or stop the flow of liquid or gas through the valve. There are usually one or more ports on the plug valves that allow fluid to flow freely when the valve is open.

  1. Bellow-Sealed Valves

Steel is used in the construction of bellow-sealed valves. The internal construction of these valve stems allows the stem to move axially, which is why they are commonly used.

  1. Ball Valves

Ball valves are available in a wide range of materials and sizes. They are available in full-flow and full-through conduits and are used for the broadest range of isolation applications.

  1. Gate Valves

When the gate valve is needed, it starts or stops a flow in a straight line and restricts the flow as little as possible.

  1. Check Valves

Check valves are sometimes referred to as non-return valves. Check valves operate automatically, rather than manually. By constantly keeping fluid flowing one way, it prevents backflow in pipes.

If you own a petrochemical industry, you need to be in contact with the best oil and gas valve manufacturers to keep the functioning in proper shape.


Oil and gas are some of the most important resources that run the whole world. This is why the oil and gas industry is the largest and most valuable. For fulfilling the drying agent demands of your petrochemical industry, you would also need to find activated alumina balls suppliers in your country or abroad.
