Webb21 feb. 2024 · The density, pore volume, porosity, and permeability of some typical sandstone cores were tested, and the results are shown in Table 3. It shows that the density of the sandstone is in the range of 2024–2360 kg/m 3, the porosity of siltstone is 8.35–13.32%, and the permeability is 0.565–2.133 mD.
WebbBerea sandstone is often used as a reference formation to study mechanisms that affect permeability in reservoir sandstones. Both heating of the pore fluid and reduction of the pore fluid salinity can reduce permeability in Berea sandstone. falls church va property recordsWebbUnlike conventional reservoirs, the genesis of low-porosity and low-permeability reservoirs and the controls of relatively high-porosity and high-permeability zones are still unclear.
