Coalbed methane is a form of natural gas that is produced from coal beds. It is composed mostly of methane, with small amounts of nitrogen, carbon dioxide, and heavier hydrocarbons like ethane. Coalbed methane is “sweet” rather than “sour.” This is because it does not contain hydrogen sulphide.
How is coalbed methane formed?
Coalbed methane is made naturally in our environment when coal forms underground. When dead plant matter breaks down in swampy areas, it eventually turns to peat and sinks further into the ground, tucked under layers of sand and mud. Over time, a combination of high temperatures and pressures causes this plant matter to harden into coal. Methane that is generated during this process becomes trapped within the newly formed coal.
We regulate coalbed methane production in the same way that we regulate other natural gas operations. The application, exploration, drilling, and production processes are all the same, as are the operational regulations.
