The report, from information and analytics firm IHS, looked at well performance for oil and oil-rich liquids in the Eagle Ford as well as in the Bakken Shale of North Dakota and Montana, currently the nation’s top play. The Bakken has more wells than the Eagle Ford, but so far, on a per-well basis, the Eagle Ford seems to be producing more than the Bakken.

This IHS report is part of a broader study that’s under way of 27 of the nation’s shale plays.
The IHS analysis shows that “Eagle Ford drilling results appear to be superior to those of the Bakken,” said Andrew Byrne, director of equity research at IHS and the study’s author.
The Bakken shale is the play against which others are measured, Byrne said, because “it was the key play that really opened up development of unconventional resources” using high-tech drilling methods and hydraulic fracturing.
The Bakken first began to show great promise about 12 years ago, Byrne said.
“The results from the Bakken were so strong that it set the standard by which all others will be measured. It was the one play that incited the industry into pursuing these opportunities,” he said.
Now, though, comes the Eagle Ford.
Wells in the Eagle Ford Shale have a stronger flow – 300 to 600 barrels a day or oil and oil-rich liquids, based on average production in a peak month – than in the Bakken, where flow ranges from 150 to 300 barrels a day.
“One of the reasons we really like the Eagle Ford is its potential as a large total resource. It could be one of the best, if not the best, in North America,” Byrne said.
“The Eagle Ford covers such a vast area. That also makes this such a strong play.”
The Eagle Ford sweeps 400 miles from East Texas to counties south of San Antonio and on to the border.
The play “gets uniformly strong results, and that’s making the play look that much bigger and better,” Byrne said.
“All plays essentially have sweet spots. What makes the Eagle Ford so good is that the noncore stuff is delivering strong results also. In some other plays, it’s only the sweet spot that’s economic.”
The Center for Community and Business Research at the University of Texas at San Antonio has also prepared studies of the Eagle Ford Shale. Center Director Thomas Tunstall predicts that the Eagle Ford Shale will produce 65 million barrels of oil for 2012. Oil production in the Eagle Ford reached 36.6 million barrels in 2011, according to Texas Railroad Commission data.
It’s somewhat difficult to predict production from the shale because the rate of production is accelerating, Tunstall said.
IHS doesn’t yet have an estimate of all the oil that is in the Eagle Ford.
“We’re working on that,” Byrne said.
Last week, Steve Trammel, senior manager of industry affairs for HIS, said in an interview that rig counts are declining in shale plays with much more natural gas than oil because of low natural gas prices.
But drilling is on the rise in shale with oil and “liquids-rich” areas, where wells can tap a mix of oil and condensate, a light oil, and “wet,” or liquid, natural gas, Trammel said.
In fact, the highest average monthly production in the Eagle Ford is coming from the formation’s liquids-rich window, Byrne said.
Asked which might be the next hot play, Byrne said: “We haven’t officially put out that opinion yet. That will have to be reserved until we finish our study.”
The energy industry is “very creative,” he noted. “It seems like every quarter another play shows up.”

Drilling in the Eagle Ford shale has dramatically increased in 2012, as producers have frantically turned away from cheap natural gas to production from regions that yield higher priced oils and other liquids.
The number of new wells drilled in Texas’ Eagle Ford shale more than doubled during the first three months of 2012, compared with the same period a year ago, according to Bentek Energy.
Operators started 856 new wells in the first quarter of 2012, compared with 407 in the same period a year ago, the energy market analysis firm reported.
There was also a record high number of 217 rigs active in the Eagle Ford during this month.
The increase in activity ratcheted up production of oil and other liquids, from 182,000-barrels-a-day in April 2011 to more than 500,000-barrels-a-day this month, according to Bentek’s analysis, which the U.S. Energy Information Administration highlighted on its website.
The Eagle Ford currently produces about 2 billion cubic feet of natural gas per day.

Energy companies in search of oil riches rivaling the biggest finds from Brazil to Angola are flocking to Texas shale, where new wells have triggered a 230- fold increase in crude output in three years
More than 115 years after a gusher 55 miles (88 kilometers) south of Dallas ushered in Texas’ first oil boom, U.S. producers such as ConocoPhillips and Marathon Oil Corp. (MRO) are counting on the Eagle Ford Shale to boost crude output amid a glut-driven slump in natural-gas prices.
Drilling for oil in the brush-covered plains of south Texas is cheaper and less risky than exploration offshore Brazil, the largest oil find in the Western Hemisphere in 30 years, and more profitable than the remote, rougher terrain of the Bakken Shale in North Dakota and Montana.
“The Eagle Ford is the top basin we have in the world today,” David Roberts, chief operating officer at Marathon Oil, told analysts and investors on a conference call last month.
Surging production in shale formations has transformed the U.S. energy landscape, flooding the market with gas and boosting domestic oil production by 14 percent from three years ago after dropping by a third in the previous 17 years, according to Energy Department data. After worries of a global oil shortage drove prices to record highs above $140 a barrel in 2008, politicians and industry executives now are discussing the prospect of the U.S. weaning itself from dependence on imports.
Marathon Oil and ConocoPhillips (COP) both plan to double their production in the Eagle Ford this year. EOG Resources Inc. (EOG), based in Houston, calls the Texas shale play its biggest source of growth, and last month boosted its estimated recoverable reserves there by 78 percent.
Oil production in the Eagle Ford jumped almost sevenfold in 2011 to surpass 30 million barrels, still less than Bakken production in North Dakota that exceeded 128 million barrels. This year daily oil production in the Eagle Ford is forecast to expand by 200,000 barrels, roughly the same amount as the Bakken, according to estimates by Wood Mackenzie Ltd. cited by Hill Vaden, an analyst with the industry consultant.
The South Texas oil fields are winning a larger portion of producers’ investment because it’s easier and more profitable to drill there compared to many prospects in the U.S. and in the world. Wells are faster and cheaper to develop, and the formation is located closer to refineries on the U.S. Gulf Coast, lowering transportation costs.
EOG said it costs about $5.5 million per well in the Eagle Ford, compared with more than $8 million per well in the Bakken, because of different well configurations. An offshore Gulf of Mexico well can cost $100 million, said Brian Uhlmer, an analyst at Global Hunter Securities LLC in Houston.
Deep-water wells can take five months or longer to drill, compared to a couple of weeks for a well in the Eagle Ford, said Brian Cain, a spokesman for Anadarko Petroleum Corp. (APC)
Producers can get a higher price for their Eagle Ford output than they can in the Bakken. Prices for Texas and Louisiana (USCRLLSS) crude this week are as much as about $38 a barrel more than production in the Bakken (USCRLLSS), according to data compiled by Bloomberg.
“The economics there are absolutely stellar,” said Danny Brown, a general manager who helps oversee Anadarko’s Eagle Ford operations. Anadarko has said it is considering selling its exploration properties offshore Brazil.
Less Political Risk
Texas provides a more stable investment environment compared to many international projects, said Pavel Molchanov, an analyst at Raymond James & Associates in Houston.
“Clearly, there’s less political risk in Texas than in Libya, let’s say, or Kurdistan,” he said. Marathon Oil last year had output suspended in Libya during unrest in that country.
The Eagle Ford cuts across a 400-mile swath of southern Texas, according to the Railroad Commission, which regulates oil and gas production in the state. Producers have unlocked the resource using advances in horizontal drilling and hydraulic fracturing, which sends jets of water, sand and chemicals underground to break up rock.
Petrohawk Energy Corp., acquired by BHP Billiton Ltd. (BHP) last year, first drew attention to the Eagle Ford when it announced a gas find in 2008, a year when futures for the fuel in New York averaged more than $8 per million British thermal units.
Expanded use of fracturing, or fracking, across the U.S. caused a surge in gas output that drove prices to a 10-year low this month of $2.204 per million Btu. Meanwhile, crude in New York has climbed 15 percent since the end of 2010 and is trading for about $105 a barrel.
The Eagle Ford will help lead a surge in state drilling permits that’s on pace to reach 25,000 this year, the most since 1985, said Barry Smitherman, the commission’s chairman.
“It’s by far the most sought-after play anywhere — not only in this country, but anywhere around the world,” said Fadel Gheit, an analyst at Oppenheimer & Co. in New York.
A Sanford C. Bernstein report last August estimated Eagle Ford production would reach 1.2 million barrels of oil equivalent a day in 2015, with 750,000 of that being liquids.
“A long-time oil field axiom is that big fields tend to get bigger over time, and that’s certainly the case here,” EOG Chief Executive Officer Mark Papa told investors during a Feb. 17 conference call. “This continues to be the hottest and highest reinvestment rate-of-return play in North America.”
