Natural Gas & Coal Bed Methane

Natural Gas

Natural gas is one of the cleanest, safest, and most useful forms of energy in our day-to-day lives. Natural gas can be found by itself or in association with oil. It is both colourless and odourless and is in fact a mixture of methane and other hydrocarbons including butane, ethane and propane.

Natural gas is found in reservoirs beneath the surface of the earth. Large layers of rock trap the natural gas as it tries to float to the surface. Although the areas where the gas is trapped are referred to as pools, the natural gas molecules are actually held in small holes and cracks throughout the rock formation.

Alberta's Natural Gas Reserves

Alberta has a world-class natural resource base, with an estimated 84 trillion cubic feet (Tcf) of remaining recoverable natural gas. Alberta accounts for almost 80% of the natural gas produced in Canada, making Canada is the world's third largest supplier of natural gas.

Alberta has a streamlined regulatory process, a highly skilled workforce, and a natural gas processing, transporting and marketing infrastructure in place.

Coal Bed Methane (CBM)

Coal Bed Methane is natural gas contained in coal. The Alberta Geological Survey estimates there may be up to 500 Tcf of natural gas in Alberta's coals. However, it is not yet confirmed what portion of this resource may be recoverable.

Characteristics of CBM

  • The natural gas found in coal is "sweet" not "sour", meaning it does not contain hydrogen sulphide.
  • It is generally of near-pipeline quality when produced and requires minimal processing. 
  • It is typically produced at lower pressures than conventional natural gas.

CBM is called an unconventional gas because the coal acts as both the source of the gas and the storage reservoir. Most of the CBM is attached to or "absorbed" on the coal surfaces and it may also be trapped in the coal fractures, which tend to have low permeability.

  • Alberta Geological Survey (AGS)

    The Alberta Geological Survey (AGS) researches and delivers geological knowledge about Alberta land and natural resources through various programs. The AGS Resource Geology program is focused on advising Alberta government agencies about natural resources.

  • Canadian Society for Unconventional Gas (CSUG)

    CSUG was formed to foster information sharing about unconventional gas among industry, government, regulators and public stakeholders. The CSUG website contains information on many different types of unconventional gas resources found in Canada, including coal bed methane.

  • Canadian Association of Petroleum Producers (CAPP)

    CAPP is an industry association focused on fostering sustainable and responsible economic growth in the Canadian upstream petroleum industry, and has background information on natural gas and coal bed methane development in Alberta.
