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碳氢化合物来源。开采泥岩中蕴藏的天然气的能力取决于沉积物组构是否适合于碳氢化合物在宿主沉积物中的运动。控制泥岩中沉积物组构的最重要因素之一是洞穴的分布，这些洞穴既可以形成多孔带，也可以摧毁它们。裂缝，包括自然裂缝和水力裂缝，将孔隙连接在一起，使页岩能够产生天然气。
