Critical moment in coalbed gas evolution determines future energy sustainability.
The article discusses how coalbed gas reservoirs form in the Qinshui Basin, China. By studying the history of coal burial and temperature changes, researchers found that the critical stage and moment of geological processes control the formation of these reservoirs. The type of coal and the amount of gas in the reservoir are determined by when the coal reaches its highest maturity level. The gas content in the coal seam depends on when the coal is uplifted to a shallower position.
