Sandstones

SANDSTONE. Sandstones are formed of lithified quartz grains between 0.06 mm and 2 mm in size. A small proportion of other mineral grains such as feldspar, mica, and rock fragments may also be present. The grains may be closely packed together forming a compact stone or sparsely distributed to form a porous stone.

Berea Sandstone Cores | Cleveland Quarries

Permeability - Berea Sandstone™ Petroleum Cores. In geology, permeability is a measure of the ability of a material (typically, a rock or unconsolidated alluvial material) to transmit fluids through it. It is of great importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs, and of groundwater in aquifers.
