Quick Answer: Is coal seam gas fracking?

In some cases hydraulic fracturing, or ‘fracking’, is used to extract coal seam gas. Hydraulic fracturing is the process of injecting fluid under high pressure into a coal seam to widen existing fractures and create new ones.

Is coal seam gas bad for the environment?

Possible environmental effects: environmental groups have raised concerns that CSG development might cause environmental damage through release of untreated production water at the surface; damage to, and contamination of underground aquifers by hydraulic fracturing; damage to wildlife habitat in sensitive areas and …

What is coal seam gas mining?

Coal seam gas (CSG) mining is a risky, invasive form of unconventional gas mining. Coal seam gas extraction usually involves tens of thousands of gas wells, with roads, pipelines, compressor stations, wastewater dams, and other infrastructure. A CSG project can spread across hundreds of thousands of hectares of land.

Is coal seam gas a fossil fuel?

Modern economies are incredibly dependent on inexpensive energy – and today that energy mostly comes from fossil fuels like conventional oil, gas and coal. … As traditional oil and gas reservoirs become more expensive to find and produce, alternatives like CSG, shale gas, solar and wind power become more attractive.

Why is fracking used in the extraction of coal seam gas and shale gas?

Fracking — or hydraulic fracturing — is used to improve the flow of gas from formations that are difficult to access due to depth and rock composition. The technique is not used for all coal seam gas deposits.

Why is coal seam gas bad?

Coal seam gas extraction can affect water in a number of ways: it could contaminate underground water if there’s a leak that enters a water source; affected water could travel between underground water sources; loss of pressure could cause fluid to move between connected underground sources; or it could contaminate the …28 мая 2018 г.

Why fracking is bad?

Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.

Why is coal seam gas good?

Using CSG to generate electricity reduces CO2 emissions by up to 70 per cent compared with coal, and gas is critical to us meeting our greenhouse reduction targets. Gas is also the perfect partner to back up intermittent renewable energy sources such as wind or solar.

Is coal seam gas the same as natural gas?

What is coal seam gas (CSG)? Coal seam gas, or coal bed methane (CBM, is a form of natural gas, typically extracted from coal seams at depths of 300-1000 metres.

What does fracking mean?

Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.

How is coal seam gas extracted?

Coal seam gas is held in place by water pressure. To extract it, wells are drilled through the coal seams and the water pressure is reduced by extracting some of the water. This releases natural gas from the coal. … In some cases hydraulic fracturing, or ‘fracking’, is used to extract coal seam gas.

How is coal seam gas formed?

Coal seam gas (CSG) is primarily methane – a colourless and odourless gas, found in coal deposits formed over millions of years from fallen trees and other plant matter. Natural gas collects in underground coal seams by bonding to the surface of coal particles.

Is natural renewable?

It’s considered renewable because of how easy it is to make, especially compared to nonrenewable energy sources like fossil fuels. … Although natural gases, no matter where we get them from, are cleaner than coal and other fossil fuels, they still produce some carbon emissions.

Is fracking used to extract coal?

FRACKING & MINING: The processes used to extract and transport minerals, metals, coal, and natural gas. … Fracking can contaminate groundwater, deplete freshwater supply, and the development of pipelines to transport natural gas could cause construction and erosion across large swaths of land.

How many fracking wells are there in Australia?

In north-east SA, fracking has been undertaken in the Cooper Basin since the late 1960s in over 700 wells. Some of Australia’s biggest gas players have gas projects in this basin, including Santos, Beach Energy (ASX: BPT), Cooper Energy (ASX: COE) and Senex Energy (ASX: SXY).
