... Shale gas formation is sensitive to high water saturation due to its ultra-low porosity and permeability, if too much fracture fluid were held up into the formation, water block and formation damage phenomenon will happen. In Fuling shale gas field, a lot of wells get ultra-low flowback rate...

... on pore size was investigated with subsequent neutron scattering. The results have revealed a vast heterogeneity, which can be related to the high clay contents. Due to the high clay contents, pores smaller than 10 nm constitute a large fraction of total porosity (25-30 %) and up to 80 % of specific...
