Coal Seam Gas

What is Coal Seam Gas?

Coal Seam Gas (CSG) is naturally occurring gas found in coal deposits. It is also referred to as Coal Seam Methane (CSM) and Coal Bed Methane (CBM). The coal deposits are formed through a process called coalification; organic matter (such as plants trees etc.) that is trapped underground under pressure with water and heat over many millions of years.

Coal Seam Gas is a by-product of the coalification process and is either form from Biogenic (generally found in the earlier stages of coalification, such as lignite) or Thermal (found in deeper later stages of coalification). The gas is absorbed into the coal through micro-pore structures, cleats, fractures and openings in the coal and held in place by water pressure.

The Composition of Coal Seam Gas is mostly Methane some Carbon Dioxide and other minor Hydrocarbons, you will also find ethane present where CSG is formed from Biogenic processes.

Coal seam gas is used in the same way as any other form of natural gas for cooking and heating as well as in industrial processes and electricity generation.

In-Situ Coal Seam Gas Analysis

IRL provides Laboratory and Consultancy services for Coal and Coal Seam Gas companies throughout Australia and Internationally. IRL provides laboratory analysis to Australian (AS 3980) and international (ASTM D7569) Standards.

Fugitive GHG Emissions Analysis and Reporting

The National Greenhouse and Energy Reporting Act 2007(Act), the Regulations made under that Act, and the National Greenhouse and Energy Reporting (Measurement) Determination 2008 (the Determination) establishes the legislative framework for a national greenhouse and energy reporting (NGER) system.

IRL can assist you with all facets of the Fugitive Green House Gas (GHG) Emissions reporting to NGER system requirements.
