Is coal seam gas LNG?

Is natural gas the same as coal seam gas?

Coal seam gas is natural gas found in coal deposits, typically 300-600 metres underground. … 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.

Is coal seam gas renewable?

Coal seam gas is a non-renewable energy resource that is a by-product of coal. … The methane gas is contained within the coal seams by water from groundwater aquifers.

Is coal seam gas mostly methane?

Coal seam gas (CSG) occurs naturally, in varying quantities, in coal seams. It consists mainly of methane (CH 4) – hence its other name of coal bed methane (CBM). Methane burns well in air, and thus can be used as fuel.

Is coal seam gas petroleum?

Every petroleum and gas project in Queensland requires a petroleum resource authority before it can begin any mining or exploration activities. This includes coal seam gas (CSG) projects. Individuals or corporations must apply for a petroleum resource authority to look for and produce petroleum and gas, including CSG.

Why coal seam gas is 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 …

What does coal seam gas do?

To produce coal seam gas (CSG), wells are drilled into underground coal seams, bringing water (CSG water) from the seams to the surface. This process reduces pressure in the seams which allows CSG to be released.

What are the two types of coal seam gas?

CSG is almost pure methane; conventional gas is around 90 per cent methane with ethane, propane, butane and other hydrocarbons making up the remainder. The difference between CSG/shale gas and conventional gas is the type of geological rock they are found in.

What is called coal bed methane?

Coalbed methane (CBM) is an unconventional form of natural gas found in coal deposits or coal seams and now considered an alternative source for augmenting India’s energy resource. CBM is formed during the process of coalification – the transformation of plant material into coal.

What is syngas formula?

Synthesis gas, or syngas, produced from coal gasification, is a mixture of gases, predominantly carbon monoxide (CO) and hydrogen (H2), along with small amounts of carbon dioxide (CO2). Calgon is sodium hexametaphosphate (Na6P6O18). It is used to remove permanent hardness(due to Mg2+, Ca2+ ions) of water.
