This publication on coalbed gas is multidisciplinary in scope and covers a wide range of aspects from exploration through production, resource calculations, emissions, and regulatory processes. One part of this volume also deals with qualifying and quantifying oil generation from coal. Furthermore, quality and quantity of oil and gas generation from coals as a function of heating mode is reported. New models for oil and gas generation in coal seams by convective heat transfer through hydrothermal circulation in basins are presented.
