Shale-Gas Output May Double by 2035, Reducing Energy Imports, U.S. Says

By Simon Lomax – Dec 16, 2010 3:41 PM MT

Production forecasts for natural gas locked in shale have doubled, which will help the U.S. become less reliant on imported energy, according to a federal agency.

[…]

The Annual Energy Outlook predicts imports will meet 18 percent of U.S. demand by 2035, down from 24 percent last year. Higher prices will spur fuel production, including natural gas, oil and coal, the agency said. Tougher energy-saving rules, such as fuel-economy mandates for new cars, and a boost in biofuel production from crops such as corn also will make the U.S. less reliant on imports by 2035, according to the forecast.

Overall U.S. energy consumption will jump 21 percent by 2035. Coal will remain the “dominant energy source for electricity generation,” although more natural-gas fired plants will be built because of higher supplies of the cleaner-burning fuel, according to the outlook.

The agency forecasts construction of five nuclear plants by 2035, contributing to a 10 percent increase in electricity generated from atomic power. The share of electricity from renewable sources such as hydroelectric dams and solar panels will rise to 14 percent in 2035 from 11 percent last year, according to the outlook.

Natural Gas Is Fantastic Now, But Let’s Not Rest On Its Laurels

without comments

This is a great example of apparent abundance of fossil fuels now becoming a strain on supply in the near future. Natural gas is clearly a comparatively clean option in the traditional energy matrix, and we ought to keep using more of it, decreasing our reliance on coal and imported petroleum. But if this article is accurate in its telling of nuclear and wind power generation decreasing because of increasing supplies of natural gas, we’re just shooting ourselves in the foot.

Another, recently posted article on this site listed about 90 years worth of natural gas available in the US, which I assume is based on current use levels. If we use more gas and less coal for electricity, and use more LNG to power our vehicle fleets, that 90 years will move down towards 50 years. Broadcasting that we have more than enough fossil fuels gives a false sense of security and lends itself to the license to continue wasting energy through inefficiency. Add in the disincentive to continue innovation in renewable energy supplies and the picture for the next generation gets pretty bleak.

Use the gas, sure, but let’s not make the ignorant assumption that we can continue with business as usual when it’s clear that, for economic, environmental, issues of national security, our energy system is in desperate need of an overhaul in the next two decades at the most.

Natural gas proves to be energy game-changer

Its sudden abundance is a boon to many and a pain to its competition

NEW YORK — By unlocking decades’ worth of natural gas deposits deep underground across the United States, drillers have ensured that natural gas will be cheap and plentiful for the foreseeable future. It’s a reversal from a few years ago that is transforming the energy industry.
The sudden abundance of natural gas has been a boon to homeowners who use it for heat, local economies in gas-rich regions, manufacturers that use it to power factories and companies that rely on it as a raw material for plastic, carpet and other everyday products. But it has upended the ambitious growth plans of companies that produce power from wind, nuclear energy and coal. Those plans were based on the assumption that supplies of natural gas would be tight, and prices high.
[…]
The U.S. uses natural gas to produce 21 percent of its electricity. Coal is the dominant fuel, accounting for 48 percent of the electricity mix. By 2015, natural gas is predicted to reach 25 percent, while coal is expected to fall to 44 percent.

[…]
Natural gas, which had traded at about $2 per million British thermal units in the 1990s, hit nearly $15 in 2005. It is now about $3.50, driven lower by reduced industrial demand and rising production by those learning to make a profit from shale gas at ever lower prices.
[…]

Plans for nuclear plants and wind farms were made under the assumption that gas prices would average $7 to $9. At that level, electricity prices would be high enough to make wind and nuclear power look affordable. Now many of these projects suddenly look too expensive.

Positives as well as Overlooked Negatives of Shale Gas

without comments

The article below is absolutely correct in explaining that energy endeavors that produce jobs and other forms of prosperity for Americans ought to be pursued. Our society needs energy to flourish just as people need work that is safe and pays decent wages.

My concern is that some shale gas operations may come with such risk, given today’s technology, that their potential costs outweigh their benefits. These costs are realized in terms of aspects such as lost work and health care, as well as un-monetized costs in potential ecological damage.

Tough choices. It’s a fascinating time to be alive. I’d happy to go in to more specifics on how we make these choices if anyone is still reading and sufficiently interested to ask.

Marcellus Shale Gas Boom: Energy, Cash and Jobs, Jobs, Jobs

August 29, 2010

By Mondoreb

Energy boom in SW Pennsylvania, Northern WV

There’s a lot of drilling for natural gas going on in the southwestern corner of Pennsylvania and northern West Virginia: the rush to tap the huge natural gas reserves of the Marcellus Shale fields. The drilling and building of pipelines has meant an oasis of prosperity during a time of dreary economic news nationwide.

JOBS, CONSTRUCTION & ENERGY IN THEM THAR HILLS

While most of the nation has been suffering through high unemployment, defaults, foreclosures and other Recovery Summer worries, one section of the country has quietly been prospering.

The southwestern Pennsylvania-norther West Virginia area has seen a boomlet of gas drilling in the Marcellus Shale field. Construction, jobs, drilling and trucks hauling equipment have been common sights along the roads of this mostly rural area during the last 18 months.

Marcellus Shale Jobs. What Kinds Are There and Where?

The Marcellus shale will turn out to be the largest job creator in Appalachia and other parts of the Northeast United States in recent history.

This massive domestic reserve of natural gas, which some experts believe holds up to 500 trillion cubic feet of gas, will provide good paying jobs for skilled and semi-skilled workers.

The Hope and Peril of Shale Gas

without comments

Here’s yet another perspective in the ongoing discussion over shale gas and hydraulic fracturing (or fracking, spelled (“fracing” below by Samuelson).

I agree that natural gas provides great promise for the next several decades, especially as it diminishes our reliance on dirtier coal and dirtier and imported oil. But let’s look at that new estimate 90 years worth of gas coming from these new, deeper sources previously locked within shale.

If we move to more vehicles powered by LNG and swap out coal for gas in electricity generation, that 90 years must shrink as estimates on availability are projected according to current use. This means that gas is very helpful to me and maybe to any kids I may one day have, but even within those kids’ lifetimes, and definitely within the lives of the next generation, we’re going to have some serious problems.

As Samuelson says, natural gas is not a panacea. Yes, we should use it, as well as planning on using every drop of petroleum and every last chunk of coal. Continued innovation on other, renewable forms of energy now, not 20 years from now, will ensure that we sill have available gas, coal, and oil 500 to 1000 years from, rather than only 50 to 100 years from now.

This also ties in with the environmental threats posed by shale gas, only briefly mentioned by Samuelson. He says that fracking has been occurring decades “without polluting water supplies,” but the movie he cites, HBO’s “Gasland,” illustrates that this is not accurate.

Developing other energy technologies means that we can hold off on drilling for the supplies that are tougher to access until safer technologies have been developed.

Increasing supply of a diverse suite of energy options while diminishing our demand makes prudent decisions much more likely than if, 30-50 years from now, we are scrambling for any energy sources that are available.

Shale gas: Hope for our energy future

By Robert J. Samuelson
Monday, August 2, 2010

You probably have never heard of oilman George Mitchell, but more than anyone else, he has changed the global energy outlook. In 1981, Mitchell’s small petroleum company faced dwindling natural gas reserves. He proposed a radical idea: drill deeper in the company’s Texas fields to reach gas-bearing shale rock more than a mile down. Because the gas was tightly packed, most engineers believed it was too costly to extract profitably. But after nearly two decades of trying, Mitchell proved doubters wrong. The result: The world has far more available natural gas than anyone suspected.

[…]

How much shale gas exists is unknown, but estimates are huge. The Potential Gas Committee is a group of geologists who regularly estimate future U.S. gas supplies. In 2000, the group’s estimate equaled about 54 years of present annual consumption; by 2008, it was almost 90 years. “This isn’t the end,” says Colorado School of Mines geologist John Curtis. Globally, one study estimated the recoverable supply at 16,200 trillion cubic feet, more than 150 times today’s annual world gas use.

Some standard drilling techniques, applied imaginatively, liberated shale gas. The first was “fracturing” (also called “fracing”): injecting liquids into reservoirs to create openings that allow the gas to flow up the drill pipe. For years, Mitchell’s engineers experimented with different “fracing fluids.” All were expensive, and the resulting gas flows weren’t profitable. In 1997, engineers tried a less costly mix of sand and water. The economics of shale gas improved dramatically, says Dan Steward, a former geologist for Mitchell.

[…]

Shale gas has many virtues, but gains will come at the margin. It isn’t a panacea for every energy ailment.
Consider the impact on oil imports. In theory, natural gas — compressed or converted into a liquid — could replace oil in some vehicles. But natural gas now fuels only about 120,000 of roughly 250 million U.S. cars, vans, trucks and buses. At today’s prices, natural gas is competitive with oil, but there’s a chicken-and-egg problem: Drivers won’t use it without filling stations; companies won’t build stations without drivers.
[…]
The second threat to shale gas is over-regulation. Environmentalists are split. Some favor shale gas as a desirable “bridge fuel” until use of non-carbon energy expands. Others argue gas drilling will threaten drinking water supplies; that was a theme of “Gasland,” a film shown this year on HBO. The charges seem overblown. As the BP spill reaffirmed, all drilling requires regulation. There are environmental issues, especially the safe disposal of “fracing fluids.” But onshore drilling, including “fracing,” has proceeded for decades without polluting water supplies. In shale gas, thousands of feet typically separate shale deposits from water tables.

Shale’s a curse and blessing for natural gas

without comments

Here’s another installment in the ongoing discussion about the potential for oil and gas from shale. It is interesting and important to put this discussion, about an uncertain technology with great negative and positive potential, in the context of the current spill in the Gulf of Mexico. Given time to work, technologies for shale and deep sea drilling both hold tremendous promise. Rushing them to market before they are ready and reliable poses equally tremendous risks.

By Myra P. Saefong, MarketWatch

TOKYO (MarketWatch) — A supply surplus has made natural gas a cheap source of energy, and its growing production from so-called “unconventional” sources such as shale may be destined to keep it that way.

“Natural gas is at a historically cheap price, assuming we’re just looking at the last ten years, but one major issue not affecting other energy markets is driving the price lower and lower,” said Neal Ryan, managing partner at Ryan Oil & Gas Partners LLC.

Driven by the nation’s growing need for energy and high natural-gas prices in recent years, interest in gas derived from shale, a geologic formation, has increased despite the high costs involved with developing the sources.

“Shale gas provides the largest source of growth in U.S. natural gas supply,” according to the Energy Information Administration’s Annual Energy Outlook 2010 report.

U.S. shale gas production was at 2.02 trillion cubic feet in 2008, up from 1.18 trillion cubic feet in 2007, government data show.

[…]

“Now many of those companies are being forced to continue drilling plans formulated for a much higher market price in order to protect those lease investments,” he said.

That’s “a dangerous spot to be in because the domestic market doesn’t need this gas right now, but companies are stuck having to protect their capital investment,” he said.

[…]

Total U.S. natural gas consumption by end use fell to 22.8 trillion cubic feet in 2009 from 23.2 trillion cubic feet in 2008, according to the EIA.

[…]

Even so, right now there are “a large number of wells that are being drilled to hold leases,” said James Williams, an economist at WTRG Economics, explaining that if a well is not drilled on a new lease within 3-5 years, then control of the mineral rights reverts to the owner and the lease is void.

Total Will Buy Texas Gas-Field Stake

without comments

There’s no doubt that these are extremely valuable resources that should be utilized. If we can be conservative in our energy use, we can hold off on exploiting resources like shale-gas, oil sands, and deep-sea resources, we can continue to develop the technology needed for extraction until it is much more efficient, economically, energetically, and ecologically.

French Oil Firm to Pay $2.25 Billion for 25% of Chesapeake Project as It Pursues U.S. Opportunities

By BEN CASSELMAN

French oil company Total SA will pay $2.25 billion for a stake in a Texas natural-gas field, in the latest sign that international energy giants are scrambling to catch up after missing out on the large U.S. gas discoveries of the past decade.

Total will get a 25% stake in Chesapeake Energy Corp.’s operations in the Barnett Shale, the biggest U.S. gas field by annual production. The discovery of the Barnett near Fort Worth, Texas, in the early 2000s launched a nationwide drilling boom that uncovered huge pockets of gas in Louisiana, Arkansas, Pennsylvania and elsewhere.

Under terms of the deal, which is expected to close by the end of the month, Total will pay Oklahoma City-based Chesapeake $800 million in cash and also will pay $1.45 billion of Chesapeake’s Barnett drilling costs over the next three years. The companies said they are also considering joint ventures in South Texas and in Canada.
