What is coal bed methane used for?
It is a primary clean energy source of natural gas. The development and utilization of CBM is of great social and economic benefit. It is a clean-burning fuel (compressed natural gas—CNG) for domestic and industrial uses. The extraction of CNG reduces explosion hazards in underground coal mines.
When was Neduvasal hydrocarbon started?

Is crude oil found in Tamilnadu?
The discovery well is situated 14-km south-east of Chidambaram town in Tamil Nadu. “Compared to earlier lower-productivity basement discoveries, Madanam-3 discovery is a major breakthrough in basement play exploration in Cauvery basin,” the company said.
What is Delta region in Tamilnadu?

Why is methane called sweet gas?
It is called ‘sweet gas’ because it does not contain any hydrogen sulphide. The gas often contains up to a few percent of carbon dioxide. In the past, coalbed methane was often the cause of numerous explosions in underground mines. In coal mines, the methane is usually held in place by water pressure.
Is Hydrocarbon harmful to humans?
Hydrocarbons are oily liquids. Many are not harmful unless the oily liquid gets into the lungs. However, if it enters the lungs, it can cause a pneumonia-like condition; irreversible, permanent lung damage; and even death.
What are effects of hydrocarbons?

What makes up 90 natural gas?
Natural gas is made up of a mixture of four naturally occurring gases, all of which have different molecular structures. This mixture consists primarily of methane, which makes up 70-90% of natural gas along with ethane, butane and propane.
Does India has crude oil?
India has an existing crude storage capacity of 5.3 million tonnes (mt), including 1.33 mt in Visakhapatnam, 1.5 mt in Mangaluru and 2.5 mt in Padur.
