Natural Gas, Marcellus Shale Play in Pennsylvania

The following article about a new natural gas exploration and production "play" in Pennsylvania and neighboring States, is a good example of how rising prices can increase the amount of oil and gas found and produced. Apparently there is a real boom going on. One of the reasons why producing gas from shale is economically attractive is because the layer of shale in the subsurface is often thick and widespread. This means it is easy to find. The rock also tends to be very impermeable and lacking in porosity (that is open space between rock particles).

Engineers have solved those problems primarily through the processes of "horizontal drilling" and "fracing" or fracturing the rock under ground by pumping fluid down the well bore and into the rock formation under high pressure. This is immediately followed with "sand" grains suspended in the fluid that goes into the induced fractures and keeps them open. This creates artificial porosity and permeability. It is an expensive and highly technical operation, but once perfected, as it seems to be, the results and the accompanying high value of the gas produced make it all worthwhile. This is a major development which can be very good for the area, and America's economy in general. It is a good time to be a working petroleum geologist and engineer.

There’s Gas in Those Hills
HUGHESVILLE, Pa. — At first, Raymond Gregoire did not want to listen to the raspy voice on his answering machine offering him money for rights to drill on his land. They want to ruin my land, he thought. But he called back anyway a week later to hear more.
By the end of February, he had a contract in hand for $62,000, and he pulled together a group of 75 neighbors who signed $3 million in deals.

“It’s a modern-day gold rush in our own backyard,” Mr. Gregoire said.
Not just his backyard either — a frenzy unlike any seen in decades is unfolding here in rural Pennsylvania, and it eventually could encompass a huge chunk of the East, stretching from upstate New York to eastern Ohio and as far south as West Virginia.
Companies are risking big money on a bet that this area could produce billions of dollars worth of natural gas.

A layer of rock here called the Marcellus Shale has been known for more than a century to contain gas, but it was generally not seen as economical to extract. Now, improved recovery technology, sharply higher natural gas prices and strong drilling results in a similar shale formation in north Texas are changing the calculus. A result is that a part of the country where energy supplies were long thought to be largely tapped out is suddenly ripe for gas prospecting.
Pennsylvania, where the Marcellus Shale appears to be thickest, is the heart of the action so far. Leasing agents from Texas and Oklahoma are knocking on doors, leaving voice mail messages and playing host at catered buffets to woo dairy farmers and retirees. They are rifling through stacks of dusty deeds in courthouse basements to see who has underground mineral rights to the deepest gas formations.

Thomas B. Murphy, a Pennsylvania State University educator who runs a program to instruct landowners on their rights, estimated that more than 20 oil and gas companies will invest $700 million this year developing the Marcellus Shale. Up to one half of that will be invested in Pennsylvania, he estimated.
The cost to companies for leasing mineral rights jumped from $300 an acre in mid-February to $2,100 now. “It shows you the pace this is going,” Mr. Murphy said. “I would call it breakneck.”
Dale A. Tice, a lawyer representing landowners in lease negotiations, said companies were on a “feeding frenzy.
A natural gas drilling site on a farm in Hickory, outside Pittsburgh, that seeks to extract gas from 600 feet below the surface.

Industry experts say in the last three years companies like Anadarko Petroleum, Chesapeake Energy and Cabot Oil and Gas have leased up to two million acres for drilling in the region, half of that in the last nine months.
Whether their bets will pay off is by no means a sure thing.
Researchers at Penn State and the State University of New York at Fredonia estimate that the Marcellus has 50 trillion cubic feet of recoverable natural gas, roughly twice the amount of natural gas consumed in the United States last year. But government estimates of the amount of gas recoverable from the Marcellus are relatively modest.
Early test results have encouraged companies to keep drilling, but most are holding details of their test wells close to the vest.

The company that has done the most work is Range Resources of Fort Worth, which says it plans to invest at least $426 million in the Appalachia region this year.
The company has reported promising results from the first 12 wells that it has drilled horizontally, the technique considered by most experts to be the most effective in the Marcellus. The most recent six have each produced more than three million cubic feet of production a day in recent months, and company executives say that is better than the average for wells recovering natural gas in the Barnett Shale in north Texas.

“The Marcellus is important to Range and it could be important to the country but it really is still early,” said Rodney L. Waller, a senior vice president at Range. “I can build you a scenario where it can be significantly better than the Barnett but it’s a function of economics.”
Energy experts say the Marcellus, along with other smaller shale formations being developed around the country, is coming under scrutiny at an opportune moment, just when conventional domestic natural gas production and imports from Canada are diminishing. With easy-to-find gas fields in decline, the country will need to explore in deeper waters in the Gulf of Mexico and penetrate deeper under the surface on land.

If all goes well, the Marcellus could help moderate the steep climb in natural gas prices and reduce possible future dependence on natural gas from the Middle East, which is beginning to arrive at coastal terminals in liquefied form.
Natural gas in the Marcellus and other shale formations is sometimes found as deep as 9,000 feet below the ground, a geological and engineering challenge not to be underestimated. The shales are sedimentary rock deposits formed from the mud of shallow seas several hundred million years ago. Gas can be found trapped within shale deposits, although it is too early to know exactly how much gas will be retrievable.

The gas from all the shales combined “is a game changer,” said Robert W. Esser, an oil and gas expert at Cambridge Energy Research Associates. He estimated that shale produced four billion cubic feet of gas a day on average last year, or about 7 percent of national production, and that shale gas production would increase to nine billion cubic feet a day by 2012, or about 15 percent of expected national production.
The New York State Energy Research and Development Authority estimates that developing New York’s portion of the Marcellus could roughly double the amount of natural gas now produced in New York. Currently that is about 55 billion cubic feet a year, providing for 5 percent of the state’s needs.

The Marcellus has suddenly become attractive in large part because natural gas prices have spiked in the last several years and the geologically similar Barnett Shale has been an industry sensation.
By using horizontal drilling techniques, oil and gas companies have been able to draw natural gas from underneath the city of Fort Worth, even from below schools, churches and airports. The companies have perfected hydraulic fracturing techniques, pumping water and sand into well bores to fracture shale and release gas from its pores.
Production in the Barnett has exploded from a trickle five years ago to over three billion cubic feet a day, and energy experts say that number could more than double by 2015. Shale gas development in other parts of Texas, Louisiana and Arkansas has also shown promise.
But no formation compares in size to the Marcellus. It is deeply entrenched in wooded and mountainous countryside and expensive to reach. But the reserve is also within short pipeline distance from some of the nation’s most energy-hungry cities.

Still, not everyone here is happy about all the leasing and drilling. At meetings with the companies, landowners have asked questions about potential hazards to water and woodlands.
Keith Eckel, 61, a grain farmer with 700 acres in northeastern Pennsylvania, said he had not decided whether to let the companies drill on his property. “Farmers have taken care of this land all their lives and don’t want to see it destroyed,” he said.
But many farmers and retirees in rural Pennsylvania appear excited that their lives are about to change.

“Now I can retire,” said Robert Deiseroth, a 63-year-old farmer and auctioneer from the town of Hickory, who recently received a $16,000 royalty check from Range Resources that he hopes will be repeated month after month. “This was a godsend for me. If it weren’t for this I would have to sell off some of my land to get some money for retirement.”
Mr. Deiseroth has put new windows in his house, bought a new fishing boat and plans to build a new garage. His 89-year-old father and 90-year-old mother, who live nearby, just got a $20,000 monthly check. His father has replaced the golf cart he drove around his farm with a Kubota utility vehicle, while his mother has bought a flat-screen television.
“When Range came in a lot of people didn’t like it,” Mr. Deiseroth said, “But things changed when they started getting their checks.”

Nice blog. Lots of good info. PA owns over 2 million acres in NC Pa and that doesn't include the ANF. Private landowners are going to get the shaft being inholders...
It sure makes sense now why the NGO's have been in a land grabbing frenzy for the past 10 years in these counties. It sure isn't about conservation now is it?

The caption on the photo in this article suggests that gas is extracted from depths of 600 feet. The Marcellus Shale is 6000 feet.

Peter said...

I'm sure the depth to the Marcellus Shale varies from one area to another. The depth to production levels will vary accordingly. The well shown in the photo may indeed be producing from 6000 feet, but this is irrelevant to the overall story.
