Many landowners are being approached with offers to lease their land. The size of the signing bonuses that have been paid in transactions between informed buyers and informed sellers is directly related to two factors: 1) the level of uncertainty in the mind of the buyer, and 2) the number of other buyers competing to make the purchase. These factors have changed significantly in a very short time.

As recently as 2005 there was very little interest in leasing properties for Marcellus Shale gas production. The Marcellus was not considered to be an important gas resource and a technology for tapping it had not been demonstrated. At that time the level of uncertainty in the minds of the buyers was very high and the signing bonuses were a few dollars per acre.

When the potential of the Marcellus was first suspected in 2006 a small number of speculators began leasing land – paying risky signing bonuses that were sometimes as high as $100 per acre. In late 2007 signing bonuses of a few hundred dollars per acre were common. Then, as the technology was demonstrated and publicized signing bonuses began to rise rapidly. By early 2008 several wells with strong production rates were drilled, numerous investors began leasing and the signing bonuses rose from a few hundred dollars per acre up to over $2000 per acre for the most desirable properties.

If the results of current and future drilling activity do not match the expectations of companies paying for leases the amounts that they are willing to pay could drop rapidly.

Before 2000, many successful natural gas wells had been completed in the Marcellus. The yields of these wells were often unimpressive upon completion. However, many of these older wells in the Marcellus have a sustained production that decreases slowly over time. Many of them continued to produce gas for decades. A patient investor might make a profit from these low yield wells with slowly declining production rates.

For new wells drilled with the new horizontal drilling and hydraulic fracturing technologies the initial production can be much higher than what was seen in the old wells. Early production rates from some of the new wells has been over one million cubic feet of natural gas per day. The technology is so new that long term production data is not available. As with most gas wells, production rates will decline over time, however, a second hydraulic fracturing treatment could restimulate production.

Throughout most of its extent, the Marcellus is nearly a mile or more below the surface. These great depths make the Marcellus Formation a very expensive target. Successful wells must yield large volumes of gas to pay for the drilling costs that can easily exceed a million dollars for a traditional vertical well and much more for a horizontal well with hydraulic fracturing.

And rock units are not homogeneous. The gas in the Marcellus Shale is a result of its contained organic content. Logic therefore suggests that the more organic material there is contained in the rock the greater its ability to yield gas. John Harper of the Pennsylvania Geological Survey suggests that the areas with the greatest production potential might be where the net thickness of organic-rich shale within the Marcellus Formation is greatest.

As recently as 2002 the United States Geological Survey in its Assessment of Undiscovered Oil and Gas Resources of the Appalachian Basin Province, calculated that the Marcellus Shale contained an estimated undiscovered resource of about 1.9 trillion cubic feet of gas.  That’s a lot of gas but spread over the enormous geographic extent of the Marcellus it was not that much per acre.

In early 2008, Terry Englander, a geoscience professor at Pennsylvania State University, and Gary Lash, a geology professor at the State University of New York at Fredonia, surprised everyone with estimates that the Marcellus might contain more than 500 trillion cubic feet of natural gas. Using some of the same horizontal drilling and hydraulic fracturing methods that had previously been applied in the Barnett Shale of Texas, perhaps 10% of that gas (50 trillion cubic feet) might be recoverable. That volume of natural gas would be enough to supply the entire United States for about two years and have a wellhead value of about one trillion dollars!

A few years ago every geologist involved in Appalachian Basin oil and gas knew about the Devonian black shale called the Marcellus. Its black color made it easy to spot in the field and its slightly radioactive signature made it a very easy pick on a geophysical well log.

However, very few of these geologists were excited about the Marcellus Shale as a major source of natural gas. Wells drilled through it produced some gas but rarely in enormous quantity. Few if any in the natural gas industry suspected that the Marcellus might soon be a major contributor to the natural gas supply of the United States – large enough to be spoken of as a “super giant” gas field.

Natural gas captured from organic shale formations is not new to the oil and gas industry; shale gas has been produced since the early 1800s (DOE, 2009).  Most shale gas formations have historically been deemed economically impractical to drill due to the available technology and relative abundance of domestic conventional natural gas sources.  However, recent technological advances in horizontal drilling and hydraulic fracturing along with increasing demand for natural gas and recent price trends for natural gas, have allowed previously inaccessible reserves to become technologically feasible and economically efficient to recover (DOE, 2009).

The Annual Energy Outlook for 2009, recently released by the United States’ Energy Information Administration, projects an increase of 0.5% total primary energy consumption annually through 2030 (EIA, 2009).  The majority of this demand increase will come from the residential sector’s demand for additional electricity (EIA, 2009).  Currently, coal-fired electricity generation dominates the electricity generation sector at approximately 49% of total U.S. domestic generation capacity (EIA, 2009).  However, due to emerging concerns and public policy developments regarding greenhouse gases and renewable portfolio standards for a sustainable energy supply, lower carbon energy sources needed for electricity generation are expected to gain marketplace demand (EIA, 2009).  Unfortunately, conversion from a fossil fuel-dependent energy economy to a low-carbon energy economy will take time and significant capital investment for infrastructure development (DOE, 2009).  A recent Wall Street Journal article cites Carl Pope, executive director of the Sierra Club as viewing natural gas as a “bridge fuel” from carbon-intensive fossil fuels, such as coal and petroleum, to cleaner future fuel sources (Casselman, 2009).

In order to meet the expected increased demand for natural gas without increasing dependence on foreign imports, development of domestic unconventional natural gas sources will need to grow rapidly.  Production from unconventional natural gas sources, namely organic shales, tight sand formations, and coal-bed methane, currently account for approximately 50% of the total domestic natural gas production (DOE, 2009), this total production from unconventional resources was estimated at 8.9 trillion cubic feet (Tcf) per year in 2007 (ALL, 2008c).  Of the 8.9 Tcf of unconventional natural gas produced in the United States in 2007, 1.2 Tcf was from shale formations; however, shale gas production is expected to grow to 4.2 Tcf by 2030, accounting for an estimated 18% of the total U.S. gas production in 2030.  Unconventional sources combined are predicted to grow to nearly 56% of total U.S. domestic natural gas production (EIA, 2009).  To date, four evolving shale gas plays (Haynesville, Marcellus, Fayetteville and Woodford) are estimated to have over 550 Tcf of total recoverable gas resources, these formatiosn are expected to be capable of providing sustainable production of 2-4 Tcf of natural gas annually for decades (DOE, 2009).  Of these four, the Haynesville Shale and Marcellus Shale may have the most significant additions to domestic reserves of natural gas in recent decades.

A 31-year-old worker died Thursday after he fell 20 feet off a natural gas rig in Towanda Township, according to Pennsylvania State Police.

At around 5:30 p.m., Greg Allen Henry, of Athens, Tennessee, was working on a Nomac Drilling site off Plank Road, two miles from Towanda, Pa.

He was attempting to dislodge a handrail while the drilling unit was being moved to another hole on the drilling pad, police said. The handrail gave way and Henry fell 20 feet, suffering a severe head injury. He was pronounced dead at the scene by Bradford County Coroner Thomas Carman. An autopsy will be conducted at a later date, police said.

A panel offers an update on legislation, which turns out to center on money.

BENTON – With interest increasing in drilling for natural gas in the Marcellus Shale, there’s a whole swirl of legislation related to it being considered in Harrisburg, but much of it comes down to money.

“A lot of what goes on in Harrisburg is who’s gonna pay to make the pie and who’s going to get a piece,” said state Rep. Garth Everett, R-Lycoming. “The fight is how we’re going to divide up the pie. … We want to see the Commonwealth get its fair share, but we also don’t want to … go New York on them and drive them away.”

Everett was among two other representatives – Karen Boback, R-Harveys Lake, and David Millard, R-Columbia – who spoke on Thursday evening at a meeting of the Columbia County Landowners Coalition.

A state Department of Environmental Protection official and a Penn State University educator were also on the panel.

Everett described the intention and status of nearly 20 bills throughout the legislature, noting that they fit into four categories: taxation and where the money goes, water protection, access to information and surface-owner rights.

While some likely won’t ever see a vote, Everett said a few will probably pass this session, including a bill that would require companies to release well production information within six months instead of the current five years.

He said a tax on the gas extraction also seems likely “at some point.”

For the most part, the industry received a pass at the meeting, with most comments favorable. One woman suggested companies might underreport the amount of gas they take out and questioned what’s being done to help landowners keep them honest.

Dave Messersmith of Penn State suggested that an addendum to each lease should be the opportunity for an annual audit of the company’s logs.

Robert Yowell, the director of the DEP’s north-central regional office, said the rush to drill in the shale happened so quickly that DEP is still trying to catch up with regulations. Likewise, he said, companies are still becoming acquainted with differences here from where they’re used to drilling.

“When they first came to town, I don’t think they realized how widely our streams fluctuated,” he said.

He added some public perceptions need to be changed – such as the belief that people aren’t naturally exposed to radiation all the time – and that he felt confident that “this can be done safely.”

In response to contamination issues in Dimock Township in Susquehanna County, DEP is upgrading and standardizing its requirements for well casings, Everett said. He added that it’s being suggested the contamination in might have been caused by “odd geology.”

“Every time humans do anything, there’s an impact on the land,” he said. “We just need to balance this right so that we end up with something we’re happy with when we’re done.”
