The Northwest Savings Bank has set-up a site for landowners interested in leasing.
It is impossible to understand with all the info on it, but go to the lower right and un-check all the boxes except Marcellus Fairway and see that of COD, only Chenanago is included
Then repeate except with Utica and see that it shows all of the Southern Tier east of the Fingerlakes as overmature, ie the gas has been cooked out.

Comment from Chip Northrup, retired oil/gas professional:
Sounds like a good well  – but sometimes they report the spikes – not a 3+ day average. 

The Utica is productive in Ohio – as wet gas (propane) oily shale =- high carbon content


It may be high carbon content in Western Pa. = the way the Marcellus is 

In NY, both the Marcellus and Utica are more likely drier gas – less valuable methane. 

And probably less productive as you go north of I 88 and N west of the Susquehanna

Utica test wells in NY (Otsego Co)  have not shown much potential.

Marcellus just start of rich Pa. reserves

New discoveries could hold even more natural gas.

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.
