U.S. Natural Gas Supply Hits Record High

Thanks to technological advancements and innovation, the United States has a growing abundance of natural gas “proved reserves” according to the Potential Gas Committee biennial assessment of the country’s gas supply.

The report finds that the United States possesses 3,374 trillion cubic feet (Tcf) of recoverable natural gas assets, the highest it’s forecast in the history of the Committee representing a 20 percent increase from 2016.

Proved Vs. Unproved Reserves

Proved reserves consist of natural gas that lies beneath the earth and can be ICEeconomically recovered with current technology. Unproved reserves are not currently recoverable because the necessary technology does not exist, it may be too expensive to economically recover them, or scientists are not certain if they exist.

Natural gas reserves can be looked at like a large iceberg. The proved reserves consist of natural gas that is known to be recoverable which is illustrated as the visible part of the iceberg – above the water. Underneath the water, a huge part of the iceberg is unable to be seen, visually representing the unproved reserves.

Each year, the amount of natural gas in each type of reserves changes. As technology and science improves, unproved reserves are then moved to the proved reserves category as they are now able to be recovered successfully.

How Much Gas is That?

3,374 trillion cubic feet (Tcf) equates to 3,740,000 billion cubic feet (Bcf) of natural gas.

A few years ago, we illustrated the power of 1 Bcf in the video below:

To help explain how much gas is stored below the U.S., ready to be recovered, we did a little math.

To give you some perspective, the 3,740,000 billion cubic feet (Bcf) of unrecovered natural gas can power over 12 trillion TVs non-stop for a century, it can provide electricity to over 82 trillion homes for a year, fuel a cross country road trip over 286 trillion times, and most impressively, fuel over 1.8 trillion rocket trips to the moon and back.

That’s a lot of gas, and as an industry, we look forward to safely and responsibly developing it to power our economy for many more decades.

Marcellus & Utica Shale Leading the Charge

The Appalachia region, specifically the Marcellus and Utica shales, contain the country’s richest supply of this natural gas. In fact, the United States is expected to account for more than half of the global natural gas supply growth through 2035, McKinsey & Company said in a new report.

According to the August 2018 report issued by the PA Department of Environmental Protection (DEP), 44 percent of the natural gas being produced in the Commonwealth is coming from the Endless Mountains (Bradford, Sullivan, Susquehanna, and Wyoming counties). What is even more impressive is that more than four percent of all the natural gas in the United States being produced solely in Susquehanna County alone.

David Spigelmyer, Marcellus Shale Coalition (MSC) president, commented on the report saying:

“Thanks to shale and production from Appalachia, the U.S. has rapidly transformed from a nation increasingly reliant on energy imports to the global leader in natural gas production. This positive shift in America’s energy outlook continues to drive meaningful economic and environmental progress while boosting national security.”

Key PGC Report Takeaways

Some key takeaways from the report include:

“The United States possesses a total mean technically recoverable resource base of 3,374 trillion cubic feet (Tcf) as of year-end 2018. This is the highest resource evaluation in the Committee’s 54-year history, exceeding the previous high assessment (from year-end 2016) by 557 Tcf (increase of about 20%).”

“The largest volumetric gains (264 Tcf or 25%) were reported in the Atlantic area. The major reason for the increase is new drilling and production results from Marcellus and Utica shale plays in the Appalachian basin.”

“The importance of shale gas in the USA is evidenced by the fact that the PGC’s mean total assessed shale gas resource of 2,107 Tcf for year-end 2018 accounts for approximately 62% of the country’s total potential resources. The growth of shale gas resources from year-end 2016 to year-end 2018 was 310 Tcf (17%).”

In conclusion, the Potential Gas Committee’s report gives evidence that the nation’s untapped natural gas supply is plentiful. The responsible development, transport and use of this natural gas will promote economic stability and our nation’s status as being energy independent.

In order to remain energy independent and provide affordable energy to the nation, the United States should encourage safe and responsible natural gas development, not restrict it.
