The cap rock would be the impermeable rock layer. Cap rocks form the top of reservoirs and create a layer that is impervious to fluid flow (Figure 1). By preventing fluids from flowing through it, the …

It depends on the connectivity of the pore space. Permeable rocks include sandstone and fractured igneous and metamorphic rocks and karst limestone. Impermeable rocks include shales and unfractured igneous and metamorphic rocks.

Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers (laminae) less than one centimeter in thickness. This property is called fissility. Shale is the most common sedimentary rock. Witryna17 sie 2024 · Shale is a kind of sedimentary rock with very low permeability and is generally considered as a natural barrier for oil and gas migration. Its matrix permeability is between 10 –12 –10 –18 m 2, while the permeability of shale fractures is much larger, generally between 10 –6 –10 –4 m 2 (Luffel et al. 1993 ).
