Gas content in the Powder River Basin is much lower than in the San Juan Basin (Table ), but the large production of gas in the Powder River Basin suggests that low gas content is compensated by large coal volumes. This also suggests that the Powder River Basin may feature a significant contribution of free (, not adsorbed) gas in its coal.
Coal. We help keep the lights on! BNSF is a critical component in coal delivery for electricity generation, industrial use and export. We offer efficient, reliable delivery through proven routes with broad access to western coal production. BNSF is a vital link to lowcost Powder River Basin (PRB) coal. Contacts.
Cretaceous The thickest section of the Powder River Basin is composed of Cretaceous rocks, an overall regressive sequence of mostly marine shales and sandstones deposited in the Western Interior Seaway Tertiary The coal beds of the region began to form about 60 million years ago when the land began rising from a shallow sea.
