How Enhanced Oil Recovery Benefits the Economy and the Job Market

Enhanced oil recovery (or EOR) – also known as tertiary recovery – is the extraction of crude oil from an oil field that cannot otherwise be extracted, and the process can extract 30 to 60-percent or more of a reservoir’s oil compared to 20 to 40-percent when utilizing primary and secondary recovery methods. According to the U.S. Department of Energy, three major techniques for EOR encompass thermal, gas injection and chemical injection, with more advanced (and speculative) EOR techniques referred to as quaternary recovery.

But as of late, there has been talk of the ways EOR can benefit the economy, as well as its employability benefits, much of it having to do with prevailing oil prices. Indeed, adding oil recovery methods increases oil’s costs, yet the increased extraction of oil can be seen as an economic benefit, with the revenue depending on the aforementioned prevailing prices. These prevailing prices depend on a myriad of factors, but also determine the economic suitability of any procedure; important to note here is that more procedures and additional expensive procedures are more economically viable at higher prices.

Benefitting the Economy: A Closer Look

Analysts believe that the use of captured, anthropogenic carbon dioxide – derived from the exploitation of lignite coal reserves – to drive electric power generation and support EOR from existing and future oil and gas wells delivers a multifaceted solution to the challenges faced by America’s energy, environmental and economic sectors. Beyond the shadow of a doubt, coal and oil resources are finite, and the U.S. in particular is finding itself in a strong position to leverage such traditional energy sources to supply future power demands, all while other sources are being developed or otherwise explored.

Let’s now get to the heart of the matter: Does increasing enhanced oil recovery actually stimulate the economy? Absolutely. According to reports such as the factsheet put forth by the Center for Climate and Energy Solutions, EOR will create and preserve high-quality vocations and enable states and local governments to realize additional revenue, reduce oil imports and trade imbalances and inject millions of dollars into local businesses.

Here are some additional statistics that support these findings:

  • Expanded EOR could provide, according to recent estimates by the U.S. Carbon Sequestration Council, up to $12 trillion – equal to about 80-percent of the U.S. national debt – in economic benefits to the country over the next three decades.
  • A report by the University of Texas Bureau of Economic Geology’s (TBEG) Gulf Coast Carbon Center quantifies the total economic activity of oil production for Texas to be 2.9 times the value of the oil produced; put simply, almost two dollars of additional economic activity is generated for every dollar of oil produced.
  • Advanced Resources International (ARI) estimates that an increase in oil production from EOR could reduce net crude oil imports by half – while providing up to $210 billion in increased federal and state revenues by 2030.

 

The Job Market Factor

 

enhanced oil recovery would require more workers

Because workers will be needed across the full EOR value chain, increasing EOR will definitely create jobs. From building and operating CO2 capture systems at power plants and industrial facilities to constructing new pipeline networks, transporting CO2 and retrofitting to give new life to existing oil fields, the future looks bright for the EOR-working relationship.

It is believed that the Kemper County Integrated Gasification Combined Cycle project in Mississippi will create around 300 permanent jobs from power plant and supply chain operators, while a proposed Midwest pipeline – which would transport manmade CO2 captured from coal gasification plants in Illinois, Kentucky and Indiana to the Gulf Coast – could create over 3,500 local jobs over a four-year construction period and over 2,000 jobs from indirect economic activity.

Thermal Oil Recovery: Current State and Future Prospects

Once a well has produced what it can via primary and secondary withdrawal methods, it’s time to move to enhanced oil recovery solutions and methods. This method also gets referred to as tertiary recovery methods and using them extracts between 30 to 60 percent of a reservoir’s original oil in place.

Enhanced Oil Recovery

Move to enhanced oil recovery (EOR) methods after having exhausted the primary and secondary techniques. Use production methods in the following order:

different enhanced oil recovery methods

  1. Primary: Primary means use gravity or the reservoir’s natural pressure to drive oil into the wellbore. These combine with artificial lift techniques like pumps to raise the oil to surface level. This results in the extraction of about 10 percent of a reservoir’s total oil reserves.
  2. Secondary: Secondary means use injection methods to displace oil. Either gas or water forced into the reservoir drives the oil into the wellbore. Combined with artificial lift techniques, this results in the extraction of about 20 to 40 percent of a reservoir’s total oil reserves.
  3. Enhanced: Enhanced or tertiary means use an injection of chemicals, gas or heat/steam to displace the oil, driving it up to the wellbore. Heat and steam comprise two of the thermal oil recovery methods. Using these methods enables the withdrawal of 30 to 60 percent of a reservoir’s total oil reserves.

Thermal Oil Recovery

While chemical techniques account for only about one percent of enhanced US production, gas injection comprises about 60 percent and thermal recovery accounts for 40 percent. Some production fields use more than one method, so the percentage equals greater than 100 percent.

California primarily uses thermal recovery. The injected steam lowers the viscosity of the oil, improving its ability to flow through the reservoir. Although all of the enhanced methods carry high costs, they remain the best available methods by which to continue well production.

Thermal methods work best in shallow oil wells, using cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD). They help increase and ease flow in oil sands. They’ve proven effective in fields in Canada, China, Indonesia, Oman, United States, and Venezuela.

Future of Thermal Oil Recovery

The future of thermal oil recovery centers on the thermal oil sands techniques and solar EOR. Thermal oil sands experienced expansion in 2015 and 2016, primarily in use in Canada. SAGD is now used in 75 percent of projects. While Chinese investments have slowed, and oil prices fluctuate, Canada alone has more than 160 projects under construction using the method.

The newest development in thermal, solar EOR uses solar panels to create the heat to produce steam. Canada also produces the best market for solar application. Thermal’s use in the US has declined. China, Indonesia, and Oman will continue to use the method in the coming decade.

Thermal continues as a go-to method for extracting oil reserves. It will continue to top the list of methods used to continue production after primary and secondary means have produced what they can.

Can Enhanced Oil Recovery Produce More Oil Output than Fracking

The Need for Fracking and Enhanced Oil Recovery

Oil is considered the most important fuel for energy and transportation needs around the globe, so enhanced oil recovery vs fracking is a hot topic of conversation for oil industry investors.

In the United States, oil fields tapped out by conventional drilling methods are still laden with extensive amounts of oil trapped in the shale. Producing more oil output could only be achieved with innovative techniques to release this trapped oil from existing wells.

Fracking has been used for years to extract the hard to reach oil and enhanced oil recovery (EOR) is quickly becoming a promising route for producing more oil output than fracking.

What are the differences between the two methods?

The Fracking Process

Fracking uses water and chemicals forced into rock formations under high pressure to crack the rock, release the trapped oil, and push it to the surface.

what is hydraulic fracturing and how does the process work

Fracking has proven to be a huge success that has brought the price of petroleum and resulting petroleum products down.

The fracking industry has become cost-effective for delivering higher outputs of oil. However, many critics question the extreme water usage and environmental pollution associated with fracking.

Enhanced Oil Recovery

The enhanced recovery idea has been around a long time but was not financially viable until now.

EOR encompasses the newest techniques used in the oil industry for producing more oil output by using methods such as pumping carbon dioxide (CO2) into existing oil wells to release trapped oil from rock formations and extend well productivity.

The CO2 acts like a lubricant and releases an impressive amount of oil that even fracking can’t reach. Oil fields in New Mexico and Texas are currently profiting from this method, with plans to tap existing fields across the country soon.

The Benefits of EOR

The benefits of enhanced oil recovery vs fracking are the highlight of the use of steam, CO2, water, or other fluids instead of a chemical/water mixture to release trapped oil.

Existing oil well projects as well as the production skyrockets, sometimes bringing up more oil than during initial drilling.

CO2-based EOR is a preferred method that offers the reward of trapping CO2 underground during the process. Reducing CO2 levels from our air and sealing it within the earth’s surface keeps global-warming activists quiet.

Another enhanced recovery process is the use of de-watering technology that turns water soaked oil into the clean water for human or agricultural use, lowering industry pollution further.

Is Fracking on its Way Out?

EOR could produce up to 4 million additional barrels per day in the United States alone. As the use of these new oil recovery methods spread, more output is expected to add to our crude oil reserves.

how the negative environmental effect of fracking is benefiting eor

The success of fracking will keep it in favor for many years, but the overall lessened environmental impact paired with heightened oil recovery will make enhanced oil recovery solutions a favorite as their benefits outperform traditional fracking methods.

Enhanced Oil Recovery Market to ‘More than Triple by 2020

Although enhanced oil recovery (EOR) currently accounts for merely 7.5 percent of total crude oil production in North America, the market is expected to grow rapidly — from revenues of $20.10 billion in 2014 to an estimated $70.60 billion in 2020 — as oil fields deplete and oil extraction becomes more complex, according to new analysis from Frost & Sullivan.

Use of carbon dioxide EOR (CO2 EOR) will be more widespread than chemical or thermal EOR as federal governments focus on carbon capture and sequestration. While chemical EOR has not shown significant growth due to long pay out times and a longer break-even point, using the right technique of injecting the chemical will help the method gain traction.

Economic stability plays a significant role in EOR deployment. When the economy is slow, the decreased demand for oil lowers oil prices and curbs the adoption of EOR. EOR is profitable only when oil prices stand at $80 per barrel or above, as the capital and operational costs of the projects are very high.

Economics also influence the selection of the type of EOR employed. With governments turning their attention to carbon capture and storage, the number of CO2-EOR projects is expected double by 2020. By 2025, 50 percent of the oil produced in the US will be through EOR; 50 percent of that will be through CO2-EOR, Frost & Sullivan predicts.

A year ago, Visiongain analysts calculated that spending in the CO2 EOR market totaled $5.3 billion at the start of 2014. This includes spending on geological studies connected to CO2 EOR, injection and production well drilling and reworking, pumping equipment, CO2 recycling facilities and CO2 distribution pipelines.
