NO to Marcellus Shale Drilling and Hydro Fracing

Marcellus Basic FactsThe Marcellus Shale formation is located in Eastern North America. The Geological formation gets it name from a nearby outcrop in the Village of Marcellus.

The Shale formation stretches across much of the Appilachian Mountain Basin.

Marcellus Basic Facts (cont.)The Marcellus Shale is a source of

untapped Natural Gas Reserves, making it one of the most attractive site for Drilling, Fracing and ultimately Energy Development.

The Gas in the Shale is produced from organic materials in the earth after they have succumb to thermogenic decomposition under extreme pressure and high temperatures.

Natural Gas in MarcellusThe Gas is usually contained within

“Pores” of the Shale. But it also found in the natural Vertical fractures of the Shale.

In April of 2009, the US Department of Energy estimated Marcellus to contain 262 TCF (trillion cubic feet) of harvestable natural gas.

Hydraulic FracturingHydraulic Fracturing is the process of

pumping water and a mixture of other chemicals into the earth under high pressures to release natural gas from the pores and grooves of the Shale.

Fracing works because the Shale won’t be able to absorb the fluid as quickly as it is being injected after a certain point. The shale begins to crack at this point and then the chemical (proppants specifically) being pumped into the earth hold the cracks open. Allowing the gas to flow freely into wells.

The Impacts of Hydraulic FracturingOf all the chemicals pumped into the earth

during Fracing, studies show that an average about 20 to 40% stay underground. These chemicals contain a compound known as Benzene. Benzene, able to cause cancer, is capable even in small quantities to contaminate millions of gallons of water.

The EPA declared that as many as 9 chemicals used in hydraulic fracturing are at concentrations that are hazardous to human health.

Laws and RegulationsNew York City, under the NYC Gas Fuel Code has made

it illegal to drill and frac within the cities limits.Pennsylvania has followed the same trend.A GEIS, or Generic Environmental Impact Statement,

provides a comprehensive review of the potential environmental impacts of oil and gas drilling and production and how they are mitigated. The Department is preparing a supplemental GEIS to assess issues unique to horizontal drilling and high-volume hydraulic fracturing of the Marcellus and other low permeability reservoirs. Governor Paterson directed DEC to supplement the GEIS when he signed the spacing bill (see Offsite Links at right).

Laws and regulations (cont).While the process of preparing the

Supplemental GEIS is ongoing, any entity that applies for a drilling permit for horizontal drilling in the Marcellus Shale and opts to proceed with its permit application will be required to undertake an individual, site-specific environmental review. That review must take into account the same issues being considered in the Supplemental GEIS process and must be consistent with the requirements of the State Environmental Quality Review Act and the state Environmental Conservation Law.

Horizontal DrillingHorizontal drilling is the process of

drilling a well from the surface of the earth to a subsurface layer just above the target gas reservoir known as the kickoff point. Then deviating the well bore from the vertical plane around a curve to intersect the reservoir at the “entry point” with a near-horizontal inclination, and remaining within the reservoir until the desired bottom hole location is reached.

Frac DrillingWhy it’s a problem

Horizontal drilling can release the trapped radioactive material

Contaminated frac water Surface run-off Where will it be stored/purified?

Source of frac waterContaminate ground water

Regulations Against FracingNew York City has passed regulations against

drilling within city limitsPittsburgh, Pennsylvania has since followed

suit in November of this yearPennsylvania has unspecified regulation of

who can authorize withdrawal of water and from what sources

Natural Gas SuppyMany believe that the shale contains over 100

years supplyRecent studies show that based on current

consumption levels there is just 7 year supply“Sweet Spots” are often smaller than

suspectedHaynesville has found less than 10% of originally

promoted land contained within “sweet spot”Barnett Shale shown only about 2 and a half

counties opposed to the original 17

Haynesville in Louisiana

Average Well Life25-35% of wells are not covering costsHow can you project future well’s declinationState of Pennsylvania does not publish

monthly production dataHow can results be analyzed or criticized

Infrastructure ProblemsInsufficient pipelines and storage capacity

Current wells being drilled to hold leases are losing profit

Plans for getting the large volumes of water needed for fracing are difficult to get approved

Waste treatment plants that are required to clean the highly contaminated frac water

What amount of land is needed to contain any problems a well may incur

Public OppositionPeople are fearful of contamination of their

drinking water as promoted by videos of residents setting their tap water on fire

Suggestion that these drill sites will be placed within protected state parks

Withdrawal of water needed for frac will be detrimental to ecosystems

Scenery degradation
