{"product_id":"2940013583481","title":"Two-Phase Flow in Coalbeds","description":"Experimental work by the Bureau of Mines indicates that when a coalbed is degassed by boreholes, the flow of methane may actually increase with time. This phenomenon appears to be the result of a relative permeability effect; that is, the coalbed permeability to the gas increases sharply with decreasing water saturation. This report reviews the background of experimental evidence indicating a relative permeability effect and presents the results of a computer simulation of two-phase flow in coal.","brand":"1001 Property Solutions LLC","offers":[{"title":"Default Title","offer_id":47082934141168,"sku":"2940013583481","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940013583481_p0.jpg?v=1763594059","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013583481","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
