Unconventional Natural Gas

By Adrian Casaday, Caroline Dykes,

Alyssa Hooks, & Marnee KirkpatrickSlide2

What is it?

Some sources are deemed "unconventional" because of their out of the ordinary geological locations. Unconventional gas is found in highly compact rock or coal beds and requires a specific set of production techniques. Types of fuel that fall into this category include tight gas, shale gas, and coal bed methane.Slide3

The Process

Hydraulic fracturing (“fracking”) is the process used to extract unconventional natural gas. Under high pressure, water and fracturing fluids are injected into a formation to create spaces in the rock pores, which allows natural gas to be freed from under the rock where it was previously trapped. Slide4

The ProcessSlide5

Net Energy Outcome

The energy used as a percentage is only about 6% for unconventional gas

Production costs of unconventional natural gas range from $2.6 to $7.6/GJ for tight gas, from $3.8 to $7.6/GJ for CBM and from $3,8 to $8.6/GJ for shale gasSlide6

Advantages vs. Disadvantages

natural gas can be a renewable resource

it can be efficiently and safely stored

more environmentally friendly due to its low emissions after burning

abundant resource

cheapest source of electrical power

government is experiencing external costs that are not directly covered from tax revenues or impact on fees on oil and gas production.

does create greenhouse gas emissions

highly volatile and can be dangerous if handled or transported carelessly

creates micro-earthquakesSlide7

Negative Impact on Environment

The picture to the right is an image of the amount of pollution UNG puts out of its smokestacks. UNG pollutes the atmosphere.

To the left, tap water is flammable due to groundwater contamination caused by fracking.Slide8

Availability

It’s availability is very high and is referred to as the future of gas supply in North America.The U.S. is the leading producing nation, yet they have only produced a small fraction of their ultimate potential. Slide9

Depletion time

Natural gas now is expected to peak around 2030. By the end of this century, nearly all of the economically recoverable fossil fuels will be gone and there will be shortages.

Expected to peak around 2020 and cause major price increases. The use of Unconventional Natural Gas will significantly improve future resource recovery.Slide10

2005 Energy Policy Act

This bill was passed on July 29, 2005 and signed into law on August 8, 2005. It was passed to help minimize the growing energy problems in the U.S. This act provided tax subsidies and loan guarantees for the production of energy.Slide11
