Description

This title is out of print. It is available electronically via the Lyell Collection.


Resources of coalbed methane (CBM), methane trapped within the porous system of coal, are many times greater than the collective reserves of all the known conventional gas fields. Yet only in the United States has this energy source been tapped. As coal is both the source rock and the reservoir for CBM there is a major paradox, whereby, in order for gas sourced by the coal not to have migrated, the coal must either be sealed or possess very low permeability. And yet for the coal bed to be an effective reservoir the gas must readily migrate into the production well. The solution to this paradox lies in a wide-ranging understanding of the geology of coal, and this volume aims to provide some of the answers.
