récupération assistée par injection de CO²

OBS: Cette méthode de récupération assistée s'applique au gaz naturel et aux hydrocarbures.

CONT: There are vast, deep coalbeds in Alberta, Canada which are unmineable but contain trapped methane. The Alberta Research Council (ARC) is leading a group of provincial, national and international organizations to exploit the coalbed methane by testing a novel process of injecting carbon dioxide. This process is called Enhanced Gas Recovery (EGR). It is similar to the established practice of using CO² injection to enhance production from oil reservoirs. With EGR, the injected CO² is adsorbed in the coal, to be stored in its pore matrix, releasing the trapped methane that can be collected and sold.
