Oil and Gas Industry Equipment: Challenges for Critical Components

The oil and gas industry both literally and figuratively fuels the global economic engine. One of the largest industries in the world, oil/gas makes use of complex, specialized equipment across the entire supply chain. From extraction, to transportation, to refining and beyond, oil/gas operators and OEM’s are challenged to engineer equipment for success across a huge variety of applications; virtually all of it needs to perform in extremely challenging operating conditions. These conditions include high temperature, high pressures, caustic chemicals, and abrasive particulate matter.

All of this infrastructure is necessary for getting oil and gas out of the ground and processing it into final products used in a huge variety of industries. While the most obvious consumer-facing outlet for oil/gas products is gasoline and motor oil, products created by this industry are vital inputs for a plethora of other industries: chemical manufacturing, plastics, and pharmaceuticals, just to name a few. 

In this article, we provide an overview of key equipment used across upstream, midstream, and downstream oil/gas workflows.

Finally, we examine how TriStar’s advanced materials are used to manufacture components that address some of the most important engineering challenges for oil and gas equipment.

Oil and Gas Equipment - How Advanced Polymer Components Are Solving Problems Across the Oil and Gas Industry

 

Oil and Gas: Key Industry Categories

Oil and gas production and processing requires a complex, multi-stage supply chain. This supply chain is typically divided into three segments: upstream, midstream, and downstream.

oil-gas-upstream-midstream-downstream

We cover each below. For an extremely detailed overview of the entire oil/gas production process, we recommend this guide here.

The corporate organization of these various industry segments varies. Some companies are specialized in extraction, refining, or pipeline operations, while others are integrated operators spread across all of these operational phases.

Upstream Oil and Gas: Extraction

Upstream Oil and Gas: Extraction“Upstream” refers primarily to the various techniques used to extract oil/gas from the earth. The precise extraction mechanism used depends on the underlying grade of oil (see below). Oil and gas extraction are distinct but closely related: in many cases, the release and capture of natural gas can occur during the oil drilling process. Gas is often dissolved in the oil itself.

What is the importance of oil/gas grades?

“Grade” refers to important chemical properties of oil/gas. These properties can vary based on where the media was extracted. For each of these grades, different operational procedures and equipment are required. For example, thicker, lower-grade oils may need to be refined at higher temperatures. Different grades also require different extraction techniques:

  • Light and medium oil can flow naturally to the earth’s surface. From there, it can typically be extracted using vertical drilling and pumping. 
  • In some geographies, light oil can become trapped in non-porous rock (sometimes called “tight” rock; shale is one famous example). This situation calls for horizontal drilling and/or hydraulic fracturing (“fracking”).
  • Heavy oil has a much thicker consistency and is more resistant to flowing. More advanced technologies are required to extract it.

How are different oil grades extracted?

The different grades discussed above require different extraction techniques. The most important categories for oil and gas extraction are “conventional” and “unconventional.”

  1. Conventional extraction refers to pumping from underground oil/gas reservoirs. Inside these reservoirs, oil sits as a liquid at normal atmospheric pressure. This fact means that it can flow through the well and into a pipeline without extensive additional processes at the extraction site. This simpler extraction process means lower costs at this stage. Conventional oil drilling can occur at either land-based or offshore drilling sites.
  2. Unconventional extraction refers to oil that cannot be extracted using traditional methods. For instance, oil sands contain oil that is mixed with thick particulate matter. This oil can be extracted using “sand mining” (where oil sands are mined directly and transported to a nearby crusher for separation) or “in situ recovery” (where advanced techniques achieve separation while the sands are still underground). The Canadian Association of Petroleum Producers provides a useful explanation of sand-based extraction here and one method for in situ recovery here

Upstream Oil and Gas Extraction Operations

Oil/gas wells are the first part of a huge arsenal of equipment used to get these commodities out of the ground, conduct preliminary processing, and prepare it for storage/transportation via the midstream segment. As noted above, the precise equipment used depends on the oil grade. The sheer variety of equipment used is too vast to cover here. We list some important examples below.

Example Oil/Gas Extraction Equipment
  • Well Head
  • Production and Test Manifolds
  • Production Separators
  • Metering and Storage Equipment
  • Storage Tanks
  • Pumps for both extracted media and support chemicals (Water, Glycol)
  • Support Systems (HVAC, firefighting systems, air pumping systems, and more)

Midstream Oil and Gas: Storage and Transportation

Midstream Oil and Gas: Storage and TransportationOnce oil and gas is safely out of the ground, it is ready for storage and/or transportation to refining facilities where it will be transformed into a salable product (or an intermediate product for use in another industry). 

Transporting Oil and Gas

Oil and gas are generally transported long distances via train, ship, or pipeline. There are some exceptions (for instance, freshly mined oil sands may be transported short distances by truck for processing). 

Trains and ships offer more flexibility (pipeline’s delivery destinations are sharply constrained by their construction). Pipelines, however, offer lower transportation costs and lower risk of environmental contamination. These pipelines cover vast distances: the United States alone features over 2.6 million miles of pipelines that transport trillions of cubic feet of media every year. These massive volumes are simply beyond the capabilities of any other transportation method. Pipelines are found above ground, below ground, and even on the ocean floor.

The same pipelines transport gas/oil extracted and owned by many different companies. These quantities are separated by “pigs,” small vehicles designed to move within the pipeline itself. Pigs are used not only to separate products, but for cleaning and monitoring/preventive maintenance.

Downstream Oil and Gas: Product Refining and Distribution

Downstream Oil and Gas: Product Refining and DistributionThis final industry segment focuses on the refining of oil and gas into various final and intermediate products, along with the sale and distribution of these products.

Downstream Oil and Gas Operations: Refining

Once oil/gas have been extracted and transported, they are ready for refining. The precise refining process utilized depends on the end product: oil and gas are core inputs for a massive variety of products. Even among fuel products, different refining processes are used to create:

  • Jet Fuel
  • Vehicle Fuel
  • Heating Oil
  • Diesel Oil
  • Fuel for electrical generation.

But these various grades of fuel are only the beginning of many end-uses for oil/gas.

What are examples of non-fuel oil and gas industry products?

The refining process creates intermediate chemicals which are then transported to the companies that turn these intermediates into final products.

  • Asphalt: the roads we drive on using petroleum-based fuels are themselves made from petroleum.
  • Plastics and Various Synthetic Materials: from packaging to vinyl home-siding.
  • Chemicals: a vast array of “petrochemicals” are refined from oil. Natural gas is used in fertilizer, antifreeze, ammonia, and many more chemicals.
  • Pharmaceuticals: even aspirin is made from benzene, a compound typically derived from petroleum.
  • Consumer goods: CD’s, DVD’s and Lipstick are just a few examples.
  • Clothing: polyester is a synthetic material found in clothes across the globe.

What are representative steps in the oil/gas refining process?

We cannot cover the specifics of the many different types of refining used for all of the product categories listed above. Below are some representative steps in petroleum refining. The U.S. Energy Information Administration provides an excellent, more detailed guide here.

  1. Separation: molecules are separated using atmospheric distillation. Oil is heated to high temperatures, causing it to vaporize so that it can be separated from other residual chemicals. A second-stage distillation process helps further separate various chemicals from the raw oil.
  2. Conversion: even after separation, heavy hydrocarbons remain. Oil is “cracked” to separate heavier and lighter molecules. That means the oil is again heated, this time with a special catalyst used to facilitate a chemical reaction.
  3. Treating: finally, fuel is treated to reduce molecules that are corrosive or prone to generating air pollution (sulfur is a prominent example). This process is also used to raise the octane levels of, for instance, automotive fuels.

Natural gas has its own unique refining requirements and processes. You can find an excellent overview here. 

 

Oil and Gas Industry Equipment: Component Engineering Challenges

Valves for oil and gas applicationsAs the different industry segments discussed above indicate, the oil and gas industry relies on massive infrastructure featuring a huge arsenal of different types of equipment. While the engineering requirements of this equipment vary by application, certain challenges are commonplace.

What are important challenges for oil and gas equipment components?

Components used in oil and gas industry equipment need to be carefully engineered to reflect demanding operating conditions. They need to meet these challenges to ensure both efficient operations and safety.

  • High Temperatures: temperatures ranging up to 500 degrees Fahrenheit are commonplace in oil/gas applications. Components need to stand up to prolonged exposure to these temperatures without deforming or otherwise compromising performance.
  • High Pressure: both oil and gas are pressurized for both transportation and a variety of refining processes. Components need to maintain performance in extremely high pressure operating conditions.
  • Caustic Chemicals: from cleaning agents to sulfuric “sour” gas, the oil and gas industry is full of caustic chemicals. Components need to stand up to chronic exposure without compromising performance.
  • Abrasive Environments: raw media often contains substantial amounts of sand and other abrasive particulate matter. Components used in the industry need to stand up to prolonged exposure to abrasion without compromising performance or lifespan.
  • Reliability: the need for reliability in oil and gas components is two-fold. First, they cannot afford to fail: premature, unplanned failure comes with financial risk and real danger. Second, they need to minimize the need for maintenance work, both to limit cost and because many of these components are deep inside complex mechanisms that are not easy to reach for routine maintenance.
  • Cost Effectiveness: some of the materials used in high-pressure/high-temperature environments are simply not cost-effective at the scale required by this massive industry. A component used as a one-off selection in aerospace may stand up to the requisite conditions but not be cost-effective in oil/gas, where a single plant or pipeline may require thousands.

How TriStar’s Self-Lubricating Components Help Address Oil and Gas Engineering Challenges

TriStar works directly with a variety of oil and gas companies to engineer components designed to thrive in challenging operating conditions.

These attributes reduce the total square feet of material required. In this application, Ultrcomp managed to reduce install, time, transportation cost, and overall material costs.

 

Learning More: Engineering-Driven Component Selection for Oil and Gas Equipment

Rulon 945 for Oil and Gas ApplicationsWe hope this guide has provided useful insight into how TriStar’s self-lubricating materials can help enhance component performance in highly demanding oil/gas applications. In our experience, the right materials selection can help tackle some of the biggest challenges for both oil/gas operators and OEM’s.

At the same time, we never present any of our materials as an all-encompassing solution. To maximize performance, reliability, and efficiency, materials need to be selected based on careful engineering analysis of the projected operating environment.

All too often, bearings and similar vibration- and impact-absorbing components are approached as commodities and sourced from the cheapest bidder. Over the long term, we think an engineering-driven approach to component selection almost always pays off. In many cases, our components are directly price-competitive with traditional metal solutions. In others, they are similarly priced but offer substantial operational benefits that bring far greater lifespan ROI. Oil/gas is a great example of an industry where the cost of failure can be extremely high and a well-engineered component based on the right materials can make all the difference.

To help engineer the right materials solutions, TriStar brings a true consultative engineering approach to our relationship with every client. We work hard to understand not just where materials can function, but where they can solve problems and help equipment work better than ever.
