These sediments have extremely low permeability, and thus prevent the CO2 from escaping.

Its low permeability to air, oils, greases, bacteria and water makes it useful for food packaging.

Injection probes are used in areas where there is very low permeability.

The field is described by low permeability, limited thickness, and geological complexity.

The rock can have extremely low permeability but production is not hampered by the presence of water.

The actual type of stratum does not matter as long as it has low permeability.

There they form a consolidated mass of much lower permeability than the surrounding sandstone.

It is resistant to ozone and has low permeability to gases.

In some cases, more area is needed if the reservoir is of low permeability.

Most of the gas-producing formations are considered tight gas, having low natural permeability.
