Shale gas ‘worse than coal’ for climate

The new kid on the energy block, shale gas, may be worse in climate change terms than coal, a study concludes.

Drawn from rock through a controversial “fracking” process, some hail the gas as a “stepping stone” to a low-carbon future and a route to energy security.

But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas.

This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well.

“Compared to coal, the footprint of shale gas is at least 20% greater and perhaps more than twice as great on the 20-year horizon, and is comparable over 100 years,” they write in a paper to be published shortly in the journal Climatic Change.

“We have produced the first comprehensive analysis of the greenhouse gas footprint of shale gas,” said lead author Robert Howarth from Cornell University in Ithaca, US.

“We have used the best available data [and] the conclusion is that shale gas may indeed be quite damaging to global warming, quite likely as bad or worse than coal,” he told BBC News.

Short-term fix?

We should not proceed to view shale gas as a ‘transitional fuel’ to be used over the next few decades to replace other fossil fuels”

Robert Howarth Cornell University

Greenhouse gas emissions from shale gas are predominantly down to two things: carbon dioxide produced when the gas is burned, and methane that leaks out while the well is being exploited.

Figures from the US government and industry indicate that at least a third more methane leaks from shale gas extraction than from conventional wells – and perhaps more than twice as much.

Extracting the gas involves a complex sequence of processes including drilling down and then sideways along a shale bed, cracking the rock with hydraulic pressure or explosions (fracking), placing plugs in the shaft and then “drilling out” these plugs.

Coal, by contrast, is associated with a much smaller methane release during mining; but burning it produces about twice as much CO2 as burning natural gas.

Molecule for molecule, methane is a much more potent greenhouse gas than CO2; but it lasts for a much shorter time in the atmosphere.

Figures from this research team indicate that over a 20-year period, the net warming impact of using shale gas is worse than coal – and, perhaps more surprisingly, that conventional gas may be worse than coal as well.

Over a 100-year timeframe, conventional gas is almost certainly better than coal – but shale gas could be worse.

The precise numbers depend most on leakage rates. Dr Howarth’s group used “best practice” estimates; in the real world, therefore, the leakage and the climate impact could be even worse.

“No-one knows for sure to what extent industry uses best practices; and unfortunately, at least in the US, industry does not want government or the public to know,” he said.

Shale gas rig Some communities see shale gas as a route to local riches, as well as energy independence

“The Environmental Protection Agency has proposed rules that would require industry to report methane emissions, but several companies have sued the EPA to try to prevent such reporting.”

With greenhouse gas emissions resuming their rise as societies emerge from recession, and with growth in fossil fuel use expanding at a faster absolute rate than renewables, some analysts and even climate campaigners have seized on the option of expanding gas use as a “transitional fuel” on the way from high-carbon coal-burning to low-carbon alternatives.

The new US analysis suggests this may not be a sensible strategy, given that the total carbon footprint appears bigger – especially if the gas comes from shale formations.

Current projections suggest that within 25 years, half of the US natural gas output will come from shale, while many other countries are also pursuing the technology.

The first trial fracking in the UK took place last month, in Lancashire.

Euan Nisbet, a geologist who runs several methane monitoring and research programmes from Royal Holloway, University of London, suggested the detailed balance might vary between geological formations.

“By trying to evaluate the greenhouse gas footprint of shale gas extraction, Howarth and his team are asking important questions about this new bonanza,” he said.

“I suspect the debate on this will be long, and the answers will be different for each shale gas formation; but it is important that we tackle this debate.”

“We also need to be very careful to account fully for the greenhouse footprint of conventional gas piped over long distances, for instance in the import of Asian gas to Europe, or Norwegian gas to the UK. The energy choices are not easy.”

The UK Department for Energy and Climate Change (DECC) is preparing to issue more fracking licences around the country, and a spokesman said it would “closely monitor developments and consider the need for additional research to improve our understanding of the implications for policy”.

Robert Howarth, however, was less equivocal.

“We should not proceed to view shale gas as a ‘transitional fuel’ to be used over the next few decades to replace other fossil fuels, but rather work harder to move towards truly green renewable fuels as quickly as possible, such as wind and solar.”

Protesters target gas landowners’ meeting

Protesters target gas landowners’ meeting. Evening Sun. Apr. 11, 2011.

 

Kurkoski, Conover and  the coalition’s Vice President Bryant  LaTourette  reminded members to stick together and to attend their
town’s board meetings in order to oppose any zoning or road use laws that might impede industries’ interest in the group’s acreage.
Conover pointed to a map of acreage within the coalition and land already leased to natural gas companies. “Looking at the map of our
holdings and their’s (Norse Energy and other companies’), the majority of the county has resoundingly spoken in favor of gas drilling,” he said

Bromide linked to oil/gas “brines”

Dr. Conrad Voltz, formerly of the Center for Environmental Health and Justice at U Pitt, testified in front of a Senate subcomittee today.   (4/11/11)

From a study he and his students did at a treatment plant that only handled “brine” from oil and gas operations in Pennsylvania, they found amongst 8 other effluents at levels that exceed standards:

Bromide, which forms mixed chloro-bromo byproducts in water treatment
facilities that have been linked to cancer and other health problems were found in
effluent at 10,688 times the levels generally found acceptable as a background in
surface water.

On March 7, 2011 Melody Kight at SUNY-ESF presented the initial
findings of her research on identifying flowback fluid contamination.

“It’s very difficult to distinguish” the source of elevated chlorides
in well or surface water, whether they’re from road salt, frack fluid,
or other sources of NaCl (salt).  Her studies indicate that the Na:Cl
ratio is at approximately 1:1 in all of them.  Therefore, a different
ratio must be used to “fingerprint” frack fluid contamination.

Parker in 1978 characterized Appalachian Basin formation brine.  He
found that as NaCl precipitates out of solution, bromide remains
dissolved in the brine.

Therefore, Ms. Kight rationalized, the Br:Cl ratio is the key.  Her
studies, using water samples from the PADEP and various calculating
and modeling software, showed that salty water from frack fluid and
from other sources have different Br:Cl ratios.

Bromide has a 0.01 mg/L detection limit.  Ms. Kight calculated that a
solution contaminated with as little as 0.0015% frack fluid could be
fingerprinted in this way.

Ms. Kight is known to be a vocal supporter of natural gas drilling, but her research may prove useful.  Landowners should ensure their water, both pre- and post- drilling, has been checked for bromide.

Rally in Albany Draws Huge Media Attention

ALBANY RALLY TO PROTECT NEW YORK FROM UNSAFE GAS DRILLING DRAWS HUGE MEDIA ATTENTION
Wes Gillingham at Albany Rally

Dear Friends,

With unprecedented, local and national coverage – including stories by The New York Times, The Wall Street Journal, Reuters, the Associated Press and papers from Texas to Canada – yesterday was a truly remarkable day for foes of fracking.

The rally gathered environmental justice and community groups and our organizers made sure our voice was heard. Catskill Mountainkeeper’s Wes Gillingham acted as Master of Ceremonies, introducing such speakers as acclaimed author Sandra Steingraber (Living Downstream), State Senator Liz Krueger, Assemblywoman Barbara Lifton, and ‘Gasland’ director Josh Fox.

Environmental groups from across New York mobilized their bases, spreading the word among members and organizing buses from every corner of the state. The result: over 450 New Yorkers lobbied their state representatives and many more turned out for a huge anti fracking rally in front of the capital. Event attendees not registered to lobby made themselves heard by protesting outside of the New York Department of Environmental Conservation building, as well as the Chesapeake Energy lobby offices – conveniently located directly next to the DEC.

The Rally/Lobby Day was an important step in our campaign to prevent unsafe gas drilling in New York State. To check out some of the news stories of yesterday’s event, please click on the links below.

From the recent news reports you’d think shale gas and fracking had just been discovered, but neither is brand new. It has been known for decades that deep shale rock formations contain lots of natural gas, and oil drillers have employed fracking for years to enhance oil recovery. But fracking for shale gas was not economical until a second technology achieved major breakthroughs in the last decade and a half: directional drilling. It is possible today to drill several wells from a single platform in many different directions, often for several miles laterally, and navigational advances enable drillers to know their exact position down to a few inches from thousands of feet away. Combined with advances in underground geological surveying, directional drilling and fracking over the last decade have allowed us to tap into previously uneconomic shale gas deposits. At the present time shale gas accounts for about 20 percent of total U.S. gas production (up from 1 percent in 2000), but it is projected to account for nearly half of U.S. gas production by the year 2035.

One remarkable aspect of the shale gas revolution is that it was not the product of an energy policy edict from Washington, or the result of a bruising political battle to open up public lands and offshore waters for new exploration. Although the Halliburtons of the world are now big in the field, its pioneers were mostly smaller risk-taking entrepreneurs and technological innovators. George P. Mitchell, an independent producer based in Houston, is widely credited as being the prime mover in shale gas, pushing the idea against skeptics. The technology was mainly deployed on existing oil and gas leaseholds or on private land beyond the reach of bureaucrats (for the time being, anyway). That is why shale gas seemed to sneak up unannounced to the media and Beltway elites, even though people inside the gas industry realized several years ago what was rapidly taking place. Mitchell worked the Barnett shale formation near Dallas, but the biggest shale gas “play” is the Marcellus​—​a massive deep shale formation stretching from West Virginia through upstate New York.

Now that shale gas is front-page news, everyone wants a piece of the action. Environmentalists, who have supported natural gas as a “bridge fuel” to kill coal, are starting to turn against gas now that it looks more abundant. Regulators want to regulate it; state legislators want to tax it more. And politicians are eager to “help” the market decide how best to use this newfound bounty, which is music to the gas industry’s ears, as they fear a glut might collapse prices and do to their industry what the collapse in oil prices in 1986 did to the small producers in the oil patch. In other words, the one thing that might disrupt this amazing success story has arrived on the scene: politics.

The shale gas revolution presents two main issues. The first concerns fracking, which is currently unregulated or lightly regulated by state and local governments. Fracking is currently exempt from some sections of the Clean Water Act and the Safe Drinking Water Act, though it is subject to all of the wastewater and hazardous material rules and regulations. Fracking fluids, once they have done their work loosening the gas, contain some toxic chemicals (and can pick up low levels of radiation from deep underground). Environmentalists are raising a predictable hue and cry about threats to groundwater from well casing leaks or from water that returns to the surface. The environmental crusade against fracking has its own Inconvenient Truth-style documentary, Gasland, by Pennsylvania filmmaker Josh Fox, which was nominated for best documentary at the Academy Awards and aired on HBO.

Gasland features dramatic footage of gas-infused well water that can be ignited at a kitchen tap, though it is not established that this is the result of nearby shale gas drilling. Hitting pockets of gas has been a well-known phenomena in shallow water wells in parts of Pennsylvania for decades. Most shale gas fracking is conducted as far as 5,000 feet underground, thousands of feet below the aquifer and beneath impermeable rock layers that separate it from drinking water. Still, spills and leaking well casings near the surface have caused some localized water pollution problems, providing just enough traction for environmentalist complaints. The EPA has launched a major study of fracking that is expected to report findings in 2014, and New York’s outgoing governor David Paterson imposed a moratorium on new gas drilling last year in response to claims that fracking threatened groundwater, even though New York’s state geologist concluded fracking presented a low risk to the state’s groundwater.

Volunteer fishing enthusiasts look for unknown trout streams and test water quality
Sunday, April 10, 2011
By John Hayes, Pittsburgh Post-Gazette
Bob Donaldson/Post-Gazette
Sean Brady of Observatory Hill, who says he’s “addicted to fly fishing,” tests the water of Pine Creek in Hampton.

In some Pennsylvania watersheds, the only thing separating Marcellus Shale drilling crews from a fortune underground could be brook trout.

Tomorrow in Harrisburg, the Pennsylvania Fish and Boat Commission will vote on the designation of 98 streams statewide as Naturally Reproducing Wild Trout Waters, following the recent discovery there of trout populations, some by volunteer anglers working in a program that trains them to do stream surveys.

The Wild Trout designation would trigger further state Department of Environmental Protection testing and possible issuance of land use restrictions in those watersheds that could limit development, including drilling.

Sixteen of the small streams and tributaries recommended for protection are located in Westmoreland, Fayette and Somerset counties. One more is in Cambria.

PG VIDEO: BASELINE READINGS ON STREAMS

As more than 800,000 Pennsylvania fishing license holders prepare for the opening of trout season on April 16 in most of the state, some angler volunteers are searching vulnerable waterways for unrecorded trout colonies, or charting baseline water conditions in Marcellus drilling zones that could be used for reference in potential pollution emergencies.

John Arway, executive director of the Fish and Boat Commission, said the water monitoring is not intended to thwart gas drilling — it’s a means of conducting “necessary research in tough economic times,” and couldn’t be done without help from citizen scientists.

“We don’t have enough eyes and ears out there. I don’t have enough biologists to monitor all of the water that we need to check to protect the resource,” he said.

Two separate volunteer water-monitoring projects with roughly the same goals are under way in Pennsylvania. One is run by Fish and Boat, the other by Washington, D.C.-based Trout Unlimited, a nonprofit cold-water conservation group with chapters in Pennsylvania. The nascent projects still lack focus and coordination in some areas, but the parallel projects are to intersect later this year and become a volunteer-based research tool of the Fish and Boat Commission.

Fish and Boat’s five-year Trout Management Plan, launched last year, calls on volunteers to provide data on 45,513 streams statewide that have never been visited by the agency’s biologists. Through the Unassessed Waters Program, volunteer students and interns at Lycoming and Kings’ colleges in central Pennsylvania take a day of training before heading out to headwaters and tributaries in specific watersheds in search of several things — most importantly, wild trout.

If Fish and Boat commissioners designate a stream section as Wild Trout Waters, DEP staffers collect additional data on invertebrates and determine if the waters will be classified a High-Quality Cold-Water Fishery (which restricts development in the watershed) or Exceptional Value Fishery (which mandates more stringent restrictions).

“Originally the program was designed to look at waters where urban development growth was highest,” said Dave Miko, Fish and Boat chief of fisheries management, who wrote the state’s Trout Management Plan. “When the Marcellus Shale industry boomed, we re-prioritized those waters with [potential drilling] activity, as well as urban growth areas. … These are waters we certainly want to go look at because we feel those waters are most at risk of degradation.”

Trout need cold water. In particular, Pennsylvania’s official state fish and only stream trout native to its waters, the brook trout (Salvelinus fontinalis), thrives in about 54 degrees. Since the sealing of many coal mines in the state, lots of small streams that 20 years ago ran red or white with toxins are now healthy enough to attract caddis, mayflies and brook or brown trout. The discovery of reproducing populations of wild trout presents a clear and unmistakable indicator of clean water, an invaluable resource.

Of prime concern to the Fish and Boat Commission are potentially high-value cold-water tributaries that flow into warm-water streams or rivers with lower water-quality ratings. The unassessed tributaries, which potentially hold trout, currently get the lower classifications and lesser protections of the waters they flow to.

The easiest way to prove fish are making babies is to identify the presence of two year-classes of a species. Under the assessment program, volunteers are trained in the use of electro-fishing devices.

“Find trout smaller than 6 inches long and 12 inches long in the same place and you know you have multiple year-classes,” said Mr. Miko. “That means they’re reproducing.”

As part of Fish and Boat’s Trout Management Plan, the Unassessed Waters Program is funded through existing resources including grants, angler licensing and permitting fees. Last year, the program’s volunteers sampled more than 65 waterways. Fifty-five percent contained reproducing populations of brown or brook trout, prime indicators that could trigger DEP involvement if the Fish and Boat commissioners change those streams’ designations tomorrow.

By next year, said Mr. Miko, the expanding program will work with nine training campuses statewide, including the University of Pittsburgh, Duquesne University and the Western Pennsylvania Conservancy.

Trout Unlimited takes a different route to the same destination.

Essentially a Washington lobbying firm funded through dues paid by chapter members, TU has no official position on Marcellus Shale drilling. But with Pennsylvania’s 52 chapters — the largest state council in TU — the regional issue has piqued the interest of the group’s leadership, which recently hired Dave Sewak of Windber, near Johnston, to coordinate its volunteer-based water monitoring program, Coldwater Conservation Corps. In southwest Pennsylvania, TU’s Penn’s Woods West, Forbes Trail and Chestnut Ridge chapters participate.

Mr. Sewak, who worked on community conservation projects at the state Department of Conservation and Natural Resources, visits the chapters to explain the program and trains volunteers to use $300 monitoring kits provided by TU national. Each kit includes a GPS unit for precise marking of locations, pH strips for measuring acidity and alkalinity, items for measuring and recording data, and one LaMotte Tracer Pocket Tester, which measures temperature, conductivity and total dissolved solids. Volunteers also take water samples that are analyzed at Dickenson College in Carlisle, south of Harrisburg, for barium and strontium, signature elements of hydraulic fracturing fluids used in Marcellus Shale drilling. Volunteers are coached to bracket a drilling location with samples taken upstream and downstream of the site.

It’s not easy — volunteers are required to return to the same sites multiple times, log precision data and adhere to a rigorous data collection protocol.

“Development is moving very rapidly, and the state just doesn’t have the wherewithal to keep track of everything, especially in rural areas,” Mr. Sewak said. “Our guys are trained to know the whole [drilling] process. We put together a conservation success index based on solid science. They’ll be testing throughout the year and have a real good idea of what the stream should look like.”

It doesn’t always work that way. Some volunteers say they wish they were given more direction.

“There isn’t much action guidance on this program,” said Monty Murty of Laughlintown, president of Forbes Trail Trout Unlimited of Ligonier. He completed the Coldwater Conservation Corps training, and plans to begin testing as soon as Westmoreland County creeks drop to normal levels.

“They leave it up to the chapters to identify the most risky sites for Marcellus Shale impact,” he said. “At our next meeting, Step 1 will be to review maps in our area and prioritize sites to test baselines.” Nevertheless, he said, “It’s good work. Something that has to be done.”

Volunteer water monitor Sean Brady of Observatory Hill said he got involved because he’s “addicted to fly fishing.” With a biology degree and a background as assistant executive director at Venture Outdoors, he’s Riverlife Pittsburgh’s development director and a Penn’s Woods West Trout Unlimited member. Having completed training, he sees the Coldwater Conservation Corps as potentially useful, but says it remains “very focused on the details, but kind of unclear on where they want us to go and what to test.”

That could change later this year. Bob Weber, head of Fish and Boat’s Unassessed Waters Program, said he’s had discussions with Mr. Sewak on bringing the citizen science programs together. “I’m going to use [the TU program] to collect water samples in a lot of these streams, to help me to prioritize where to send sampling crews, and Dave [Sewak] will be the liaison between the Fish and Boat Commission and the TU chapters,” he said.

Steve Forde, a spokesman for the Marcellus Shale Coalition, said he wasn’t aware of the details of the volunteer testing programs, but in general the industry would welcome it.

“I think we have shown over several years we embrace added transparency on a variety of levels,” he said. “We are a highly regulated, highly transparent and consequently highly sophisticated industry, particularly when it comes to water quality.”

Mr. Arway said he believes gas can be extracted from Marcellus Shale without polluting water resources.

“Most operators,” he said, “want to do this well and safely.”

Forbes Trail Trout Unlimited members will choose assessment sites at their next meeting, 7 p.m. April 20 at the Winnie Palmer Nature Reserve in Latrobe, 724-238-7860.

Marcellus just start of rich Pa. reserves

New discoveries could hold even more natural gas.

By Andrew Maykuth

Inquirer Staff Writer

Natural gas drillers are accelerating exploration of several Appalachian rock formations that sandwich the Marcellus Shale beneath Pennsylvania, and some experts say the new discoveries may be as prolific as the Marcellus itself.

“What we’ve got is Marcellus times two,” said Terry Engelder, the Pennsylvania State University geosciences professor whose Marcellus Shale estimates in 2008 first drew public attention to the region’s shale gas potential.

Since The Inquirer reported in May that drillers had found recoverable gas in the Utica and Upper Devonian Shales, several operators have become more openly optimistic about a potential natural gas triple play in the region. The new discoveries add momentum to an industry that is rapidly reshaping the economy and the environment of large swaths of rural Pennsylvania.

“A year ago, I didn’t have a feeling the tests were going to be as large as I’ve seen,” Engelder said. “The implications of this are just amazing.”

Range Resources Corp., the Texas company that drilled the first Marcellus well in 2004, is bullish about multiplying output from its acreage, mostly in southwestern Pennsylvania.

“The Utica and Upper Devonian could combine to equal the Marcellus,” Range spokesman Matt Pitzarella said, though he cautioned that the estimates were preliminary.

At least four gas drillers, including Range, told investors this year they were exploring the formations, which lie above and below the Marcellus in a geological layer cake.

The expanding outlook of shale gas reserves goes far beyond Pennsylvania.

Worldwide estimates of gas reserves are growing because of revolutionary advances that couple horizontal-drilling techniques with hydraulic fracturing to unlock gas in long reaches of tight rocks.

The U.S. Energy Information Administration on Tuesday said technically recoverable shale gas worldwide could add 40 percent to global gas supply. China, South Africa, Argentina, and Australia have big reserves. So do Mexico and Canada.

According to the administration, American natural gas reserves are now at the highest level in 40 years. By 2035, shale gas will account for 46 percent of U.S. natural gas production.

Though gas burns cleaner than coal or oil, the escalation of an industrial extraction process that produces large volumes of toxic wastewater has raised fears about the trade-offs of shale gas. President Obama has championed natural gas development, but only if it can be done without endangering water supplies.

“It’s a little disheartening the industry is wringing its hands in excitement when they clearly haven’t figured out how to drill in the current shale without creating problems,” said David Masur, executive director of PennEnvironment, a lobbying organization.

Pennsylvania regulators on Wednesday pressed Western Pennsylvania water suppliers to expand the scope of tests to screen for radioactive pollutants and other contaminants from the natural gas drilling industry.

So far, 2,748 Marcellus wells have been drilled in Pennsylvania – 399 in the first three months of 2011. Experts say 50,000 wells could be drilled in the coming decades, not counting wells in other formations.

“We’re still in the early stages of this,” Masur said.

Awareness of the presence of gas in other Appalachian formations – even deep ones – is hardly new. Some operators, such as Anadarko Petroleum Corp., were attracted to Pennsylvania to explore other deep formations and then switched to the Marcellus. Range’s first Marcellus well had targeted a deeper formation called the Lockport Dolomite.

The potential of the Marcellus has eclipsed all other formations. In the last 150 years, operators have produced 47 trillion cubic feet of gas from Appalachian wells, Pitzarella said. By comparison, the Marcellus Shale is believed to contain 500 trillion cubic feet, though the amount eventually recovered will be less.

In recent months, operators have begun to focus capital on some of the other formations.

Atlas Energy Inc. executives, before their company was sold to Chevron Corp., told analysts they were exploring the Utica formation and the Upper Devonian Shale.

“Both of these shale packages are prevalent throughout Western Pennsylvania and New York, where we have over 630,000 net acres,” Atlas president Richard D. Weber said in August.

Consol Energy Inc., a Pennsylvania coal producer that last year moved aggressively into natural gas, said it had a promising Utica well last year in eastern Ohio.

Brandon Elliott, Consol’s vice president for investor relations, told investors on Feb. 28 that a vertical well produced 1.5 million cubic feet of gas from a 200-foot-thick Utica layer 8,450 feet below the surface.

That production, which required no hydraulic fracturing, “actually would be greater than any of our other vertical wells that we drilled in the Marcellus,” Elliot said.

Consol has budgeted $35 million to drill six more Utica wells later this year, he said.
