- "Since roughly mid-2006, Garrett and Allegany Counties have been receiving considerable interest by energy companies as a possible source of natural gas from a geologic formation known as the Marcellus Shale. The Marcellus Shale has long been known as an organic-rich shale in the Appalachians, occurring at the surface and in the subsurface from New York to eastern Tennessee. However, the Marcellus had never been a target for gas exploration because it was not economical for the companies involved.That is about to change, as drilling techniques developed in the past ten years are being used in the Marcellus in Pennsylvania (and to a lesser extent in West Virginia) and will soon be used in New York and Maryland."

- "The Oriskany Sandstone is the main deep gas reservoir in western Maryland. Appalachian gas drillers have long suspected that the dark gray to black shale, known as the Marcellus Shale, that overlies the Oriskany was the likely source for the gas within this prolifically productive sandstone. The Marcellus was considered “tight” or unproductive as a potential gas reservoir, but recent innovations in gas well drilling and stimulation have changed that long-held paradigm. In 2003 Range Resources was the first company to prove that the tight shales of the Marcellus could produce economical amounts of gas if drilled and stimulated unconventionally."

- "Methane in well water has been repo rted anecdotally over the years in the Appalachian Plateau of Maryland; however, no systematic study has been conducted regarding methane occurrence an d distribution. The potentia l development of natural gas reserves in the Marcellus Shale in western Ma ryland has raised concerns about whether these activities could resu lt in methane contamination of the wa ter-supply aquifers in the region. Well water is not routinely tested for meth ane in Maryland, since it does not have an established Primary or Secondary Maximum C ontaminant Level (MCL). Because of the concern over possible methane contamination of water wells resulting from Marcellus Shale gas-development activities, the Maryland Ge ological Survey (MGS) evaluated methane samples from 49 wells in 2012 and an additional 28 wells in 2013 in Garrett County and western Allegany County. The purpose of th is study was to measure ambient methane concentrations in water wells in the region, and to begin to gain an understanding of the occurrence and distribution of me thane in water wells. This report discusses the methane data collected in both years."

- "Thanks to the U.S. Energy Information Administration (EIA), new updates to maps and geological information for the Marcellus Shale formation has allowed for a better understanding of the shale’s structure, thickness and extent.
In order to create these maps, the EIA uses data collected from the wells in the formation. The maps show the formation’s extent and the structure of the areas that are productive and prospectively productive. The structure and thickness maps are extremely important when determining resource estimation and when defining areas where hydrocarbon extraction is practical...."

- "The Settled Science of geology incorporates the quaint notion that the Earth’s petroleum deposits were formed via the “anaerobic decomposition of buried dead organisms”.
Western mainstream petroleum geologists accordingly classify petroleum as a “fossil fuel” [aka decomposed dinosaur detritus] because these “dead organisms” are “typically” believed to have been “buried” millions of years ago."

- "Shale gas plays in the United States are commercial failures and shareholders in public exploration and production (E&P) companies are the losers. This conclusion falls out of a detailed evaluation of shale-dominated company financial statements and individual well decline curve analyses. Operators have maintained the illusion of success through production and reserve growth subsidized by debt with a corresponding destruction of shareholder equity. Many believe that the high initial rates and cumulative production of shale plays prove their success. What they miss is that production decline rates are so high that, without continuous drilling, overall production would plummet. There is no doubt that the shale gas resource is very large. The concern is that much of it is non-commercial even at price levels that are considerably higher than they are today. "
