Category Archives: Shale Gas
Shale gas is natural gas produced from shale. Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020
The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey.
The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 9 million barrels of unconventional natural gas liquids.
The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States. The Marcellus Shale, at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed. This is followed closely by the Greater Green River Basin in southwestern Wyoming, which has 84 TCF of undiscovered natural gas, of which 82 TCF is continuous (tight gas).
“Understanding our domestic oil and gas resource potential is important, which is why we assess emerging plays like the Utica, as well as areas that have been in production for some time” said Brenda Pierce, USGS Energy Resources Program Coordinator. “Publicly available information about undiscovered oil and gas resources can aid policy makers and resource managers, and inform the debate about resource development.”
The Utica Shale assessment covered areas in Maryland, New York, Ohio, Pennsylvania, Virginia, and West Virginia.
Some shale rock formations, like the Utica and Marcellus, can be source rocks – those formations from which hydrocarbons, such as oil and gas, originate. Conventional oil and gas resources gradually migrate away from the source rock into other formations and traps, whereas continuous resources, such as shale oil and shale gas, remain trapped within the original source rock.
These new estimates are for technically recoverable oil and gas resources, which are those quantities of oil and gas producible using currently available technology and industry practices, regardless of economic or accessibility considerations.
This USGS assessment is an estimate of continuous oil, gas, and natural gas liquid accumulations in the Upper Ordovician Utica Shale of the Appalachian Basin. The estimate of undiscovered oil ranges from 590 million barrels to 1.39 billion barrels (95 percent to 5 percent probability, respectively), natural gas ranges from 21 to 61 TCF (95 percent to 5 percent probability, respectively), and the estimate of natural gas liquids ranges from 4 to 16 million barrels (95 percent to 5 percent probability, respectively).
USGS is the only provider of publicly available estimates of undiscovered technically recoverable oil and gas resources of onshore lands and offshore state waters. The USGS Utica Shale assessment was undertaken as part of a nationwide project assessing domestic petroleum basins using standardized methodology and protocol.
The gas fields extend from the booming Eagle Ford play of South Texas deep into the ranch and coal country stretching inland from this violent border city. This is Zetas country, among the most fearsome of Mexico’s criminal badlands.
U.S. and Mexican energy companies long have been besieged by the gangsters here – their workers assaulted, extorted or murdered – despite a heavy military and federal police presence. Now, with feuding Zetas factions bloodying one another and fending off outside rivals, what has been a bad situation threatens to get much worse.
Northern Mexico’s gas production has suffered for years as gangland threats or attacks have kept workers from servicing the wellheads, pipelines and drilling rigs in the Burgos Basin, the territory between the Rio Grande and the city of Monterrey, which now provides up to 20 percent of Mexico’s natural gas.
“Petroleos Mexicanos has problems with security … principally in Burgos,” Guillermo Dominguez, a senior member of the National Hydrocarbons Commission, told the Mexico City newspaper Reforma.
And now the surging Zetas bloodletting pits the gang’s top bosses – Heriberto Lazcano and Miguel Angel Treviño – against Ivan Velazquez, a former underling known as “El Taliban.” From his base in the western state of Zacatecas, Velazquez reportedly has allied with the remnants of other gangs to launch a challenge for control of Coahuila state, which holds most of the shale gas reserves.
Challenge to control
Banners recently hung by both Zetas factions have accused one another of treason and other transgressions that will be avenged with death. Fighting has rattled Nuevo Laredo, the Zetas stronghold that also is the busiest land port for U.S.-Mexico trade, killing scores this month alone.
Still more banners appeared in Nuevo Laredo Tuesday, reputedly written by beleaguered civilians, promising all the gangster factions further bloody vengeance.
“Zetas are pretty much in control, but they have been challenged,” said a U.S. official in Mexico who monitors the situation, speaking on condition of anonymity. “You have all these groups fighting one another, shifting alliances and internal fights … It’s a wilderness of mirrors.”
The Zetas’ spats with rivals already have turned Coahuila’s other large cities – Torreon in the west, Monclova in the center and Saltillo in the east – into fierce gangland battlegrounds. State officials are blaming the Sept. 17 escape of 131 prisoners from a Piedras Negras prison on the Zetas seeking to replenish their ranks for new battles.
The insecurity in Mexico’s gas fields contrasts sharply with the drilling and production frenzy seizing the ranchlands just north of the border. Oil field pickups and semi-trailer fuel tankers choke Highway 83, the once-desolate ranch-country highway that cuts northwest from Laredo though the lower reaches of the Eagle Ford.
Some 6,000 drilling permits have been issued for Eagle Ford shale in Texas, and 550 wells are producing there. By comparison, Pemex so far has drilled five exploratory shale gas wells, but hopes to drill 170 more in the next four years. The company plans to spend $200 million on exploration in the short term.
Those first exploratory wells have been drilled to the west of Nuevo Laredo and below the border at Piedras Negras, ranch and coal country that remains relatively violence free for now. But that tranquility may owe more to the now-threatened dominance of the Zetas bosses than to rule of law.
“They are in control,” said a U.S. official. “They are pretty much just doing their thing.”
At least eight Pemex and contract employees vanished in May 2010 near a gas facility near Falcon Lake, territory under the Zetas’ firm control. Last March, two men working for a Mexican company doing contract work for Houston-based Halliburton disappeared outside Piedras Negras.
Halliburton spokeswoman Tara Mullee-Agard said employees get regular security briefings, but the company declined to comment on the contractors’ disappearance.
“Many companies that were active in the areas have stopped until Pemex or the government can provide security,” said an employee of one Reynosa-based company. “In places where there have been incidents we don’t operate anymore. When darkness falls, we stop wherever we are.

State-run gas company GAIL is just steps away from signing a 20-year contract for shipping two million tonnes of LNG a year from US east coast, The Times of India said, citing sources close to the development.
Value of this contract would be approximately $12 billion.
GAIL executives were in the US last week in order to give final touches to the deal, the newspaper said.
In December 2011, GAIL inked a $20 billion contract with Sabine Pass Liquefaction for 3.5 million tonnes of LNG annually.

(Reuters) – About six years ago, an army of agents hired by energy companies started desperately courting landowners across the United States whose farms and ranches happened to sit atop some of the richest oil and gas deposits in the world. And so began one of the biggest land grabs in recent memory.
Those days are over.
U.S. energy titan Chesapeake Energy is quickly cutting back on an aggressive land-leasing program that in recent years has made it one of America’s largest leaseholders, putting an end to half a decade of frenzied energy wildcatting.
Beset by growing governance and financial problems, and a sharp slump in natural gas prices, the No. 2 U.S. gas driller is reducing by half the ranks of its agents, known in the industry as landmen.
With little evidence that its competitors are taking on the role of leading industry lease-buyer, Chesapeake’s new found frugality is expected to usher in a more sedate period of U.S. land buying, and a sizeable cultural shift for an industry that has been acquiring new acreage at almost any cost.
A surge in drilling into rich shale-gas seams from Pennsylvania to Texas has pushed natural gas prices to 10-year lows, forcing producers, including Chesapeake, to cut output and put the brakes on new wells.
Drilling simply to hold on to leases represents about half of U.S. natural gas output, analysts say, which has helped keep production at record highs despite plummeting prices. Leases held by energy companies tend to last about three years, but will typically remain valid indefinitely if an energy company drills wells and produces fuel on the leased acreage.
It should be fairly easy for drillers to re-hire agents and secure more land when prices recover, according to landmen sources, and production is not expected to be affected immediately. But a lull in leasing could briefly affect production longer term, given that it takes up to six months to secure large tracts of land.
“Chesapeake has always been a bellwether for where the next big play is. It would come, lease large blocks and send a signal to the market,” said Adam Bedard, senior director at Bentek Energy in Colorado. “Without them, the pace of land acquisition might slow.”
In a move to mollify disgruntled shareholders, Chesapeake plans to reduce its use of contracted landmen from 1,300 now to 650 by the end of the year, said Chief Executive Aubrey McClendon, who was stripped of his chairmanship last month after Reuters reported a series of governance missteps.
The reduction, which is expected to help reduce towering debt levels, marks an 80 percent decrease from its peak of 3,400 landmen, McClendon said.
The cull has begun. Over the past month, 225 contracted landmen were cut from Chesapeake jobs, said one Ohio-based landman, who, like most in the close-knit industry, would only speak off the record.
“Chesapeake’s activity level in the Appalachian region is minimal now. It has devastated the (landman) industry,” the source said. “The Chesapeake debacle is one thing, but the rest of the industry shortfall is because a lot of the projects are intertwined with Chesapeake,” he added.
The Oklahoma-based company has become one of the largest leaseholders in the United States, amassing more than 15 million acres of land for drilling or an area about the size of West Virginia.
One mid-sized U.S. brokerage that does lease work for Chesapeake has experienced a 15 percent to 20 percent fall in business over the last 90 days due to a slowdown not just in Chesapeake activity but across the board, a manager for operations at its eastern division told Reuters. About 15 percent of that company’s business comes from Chesapeake, he said.
“We are getting to the point where companies are becoming more cautious – that is what we are seeing,” he said, asking that he not be named.
Other major producers, including Encana Corp, Royal Dutch Shell and Chevron, said they are not planning to materially change their strategy of land acquisition or staffing numbers, suggesting a gap might be left as Chesapeake, long the pioneer in drill leasing, retreats.
“We have not reduced our land staff nor have we made any changes in the way we conduct land operations,” said a spokesman for Encana, one of Chesapeake’s main land-leasing rivals. Encana employs an in-house staff of about 170 workers in its land department. Shell also said it was “not planning any major staffing level changes in our land function for leasing activity.”
Landmen in the field reckon companies are now well-placed to increase leasing again when they need to, but it could take up to six months between a decision to lease the land and the drilling, potentially creating a lull in activity, sources said.
While a fall in leasing will affect the landmen, it is unlikely to affect gas output for quite some time given the amount of land already leased and the hundreds of wells drilled that have yet to begin producing.
“The huge land grabs in the gas plays are coming to an end,” said one energy hedge fund manager. “Even without more leasing, however, these companies have backlogged a huge inventory of drilling locations.”
The backlog of 3,500 oil and gas wells in the United States is about 1,000 more than usual, according to Randall Collum, a natural gas analyst at Genscape in Houston.
It could take more than a year to exhaust the natural gas portion of that supply as pipelines come online to connect new producing regions, such as in Ohio, to areas of higher demand, he said. Moreover, the reserves accumulated over the last decade are expected to take longer to dwindle away.
That scenario is likely to put a cap on prices in the near term, with or without Chesapeake.
AFTER THE BOOM
When U.S. drillers employed new technologies during the last decade to economically tap oil and gas from shale rock, results showed the potential for a massive revival in waning domestic production.
In 2006 and 2007, companies began rushing to acquire new leases. Geologists pored over maps, in search of the sweetest acreage. Landmen were hired like never before, court houses in energy-rich regions filled with workers quickly securing leases. Rural and depressed areas in Pennsylvania, North Dakota, and Ohio became, by geological coincidence, new target areas for energy companies.
Teams of between 50 and 100 landmen were charged with securing hundreds of thousands of acres in a matter of weeks. Some would knock on landowners’ doors, while others specializing in title work would make the lease legally secure and determine, among other things, who receives royalties on the production.
Chesapeake led the charge, spending billions of dollars a year on speculative leasing, helping to push land prices higher in energy-rich regions. In 2011, it became the lead acreage holder in the Utica formation shale in Ohio with 1.5 million acres, and was the first to publish production figures from new wells there.
After Chesapeake arrived, other majors such as Anadarko and Exxon Mobil quickly followed. Much of the best drilling areas have already been swept up in what is now thought – though not fully proven – to be one of the most promising oil and gas plays in the country.
Now, five years after the boom began, natural gas output is at an all time high. The success has, in many ways, backfired. Prices have dropped so far that companies can barely afford to drill in pure natural gas plays. Chesapeake, the self-proclaimed ‘champion’ of U.S. natural gas, is facing a $10 billion cash-flow shortfall this year, forcing it to rein in spending.
“It will slow down the overall aggressiveness if Chesapeake isn’t out there leading the charge,” said Genscape’s Collum. “But it is all about prices. If prices rise then companies will come back in.”
