Shale gas is an increasingly important source of hydrocarbons for the petroleum industry. The ability to exploit the gas held in mudstones is dependent upon the sediment fabric being suitable to allow movement of hydrocarbons within the host-sediment. One of the most significant factors controlling sediment fabric in mudstones is the distribution of burrows that can either create porous zones or destroy them. Fractures, both natural and hydraulically induced, link the pores and allow gas to be produced from the shale.

页岩气是石油工业日益重要的烃类来源。 开发泥岩中所含气体的能力取决于沉积物组构是否适合允许烃类在主沉积物中运动。 控制泥岩中沉积物组构的最重要因素之一是洞穴的分布，洞穴可以产生多孔带或破坏多孔带。 天然和水力引起的裂缝将孔隙连接起来，并允许从页岩中生产天然气。
