From mudstone to conglomerate, rock permeability increases with an increase of grain size, with only an exception of siltstone which has a relatively larger porosity value. Finally, regression analysis show that there is a good fitting ( R 2 =0.95) between permeability and porosity which could be easily used to derive reliable permeability ...Terms such as claystone and siltstone are often used in place of mudstone ...

It is mudstone and shale, mud-containing, clay and silt. Siltstone is different because it is mostly clay and not clayy. Silt stone is much less common than shale and sandstone.Figure 1 Characteristic log shapes for different types of sand bodies set in shale, (a) Funnel shape, coarsening upward. Note that this is the shallowest interval, so the shale is least compacted. (b) Cylinder shape, blocky. Note that the SP log is featureless because the borehole salinity is the same as formation salinity.
