Shale Gas(셰일 가스) Shale is one of the most common sedimentary rocks in the world and it is primarily composed of clay and fragments of other minerals such as quartz and calcite. Shale can be the source‚ reservoir and the seal for natural gas. Shale formations normally have low permeability (limited ability for gas or fluids to flow easily through the shale formation) and normally require stimulation techniques (such as fracturing) to economically produce shale gas. Shale gas is natural gas that

WHAT IS COAL SEAM GAS (CSG)? CSG is a naturally occurring methane gas which is known as Coal Bed Methane (CBM). It is a-by product of ancient plant matter that has formed over millions of years by the same natural processes which produce coal. Not long ago this gas was identified as a major problem in the underground coal mining industry due to it’s high flammability despite this‚ it is now recognised as a very profitable resource. The coal seams are generally filled with water and it is the

Shale gas is natural gas formed from being trapped within shale formations. Shale gas has become an increasingly important source of natural gas in the United States over the past decade‚ and interest has spread to potential gas shale’s in the rest of the world. In 2000 shale gas provided only 1% of U.S. natural gas production; due to rising oil prices gas prices have also been affected by the rise therefore there was big demand for gas in the US which in 2010 it was over 20% and the U.S. government’s

Coal Seam Gas What is it? Coalbed methane‚ also more commonly known as coal seam gas (CSG) in Australia‚ is a type of natural gas removed from coal beds. It has been labelled as an unconventional natural gas along with tight gas and shale gas. They are labelled as "unconventional" as a result of their unusual reservoir types. It is removed from coal seams that are 300 - 1000 metres underground‚ and it is mainly composed of methane gas. It is typically extracted by drilling a steel-encased hole

5561 - A World with Only Electric Vehicles Today our lives are thought to be in danger due to global warming. Global warming is defined as a gradual increase in the overall temperature of the earth’s atmosphere caused by increased levels of carbon dioxide‚ chlorofluorocarbons‚ and other pollutants. Thought to be a big contribution to global warming are the emissions that come from the exhaust of our cars. Electric vehicles do not have tailpipes that exhaust fumes to pollute so they are the logically

Gas leak detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial

an auto parts manufacturer is planning to expand its struggling ABC Filters into filters for Gas Turbines. Recently ABC ’s R&D department developed a cartridge-shaped ’E-10 ’ synthetic filter with a lot of superior features than it competitors. However ABC lacks deep knowledge about the natural gas power generation filter market. This presentation is attempting to assess the attractiveness of Gas Turbine filter market and providing a market strategy to ABC Filters for their product launch

What needs to be done to achieve greenhouse gas reduction targets by 2020? Since the beginning of Industrial Revolution‚ concentrations of carbon dioxide‚ methane‚ and nitrous oxide have all risen dramatically because of human activities. Fossil fuel combustion‚ land-use change‚ increasingly intensive agriculture‚ and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet’s atmosphere include water vapor and ozone. Carbon

“THE GAS MAN COMETH” The documentary‚ “Gas Land”‚ by Josh Fox‚ is a film about the problems with contaminated groundwater due to excessive and unregulated natural gas extraction across the country. In the film‚ Fox travels all over to talk to many people who have rented out their land to natural gas companies‚ only to get contaminated water and no help from any company or organization with the problems that ensue. Fox uses many techniques in his film to get across his point that America should
