Berea Sandstone™ Petroleum Cores
For the past 30 years, Berea Sandstone™ core samples have been widely recognized by the petroleum industry as the best stone for testing the efficiency of chemical surfactants.
Berea Sandstone™ is a sedimentary rock whose grains are predominantly sand-sized and are composed of quartz sand held together by silica. The relatively high porosity and permeability of Berea Sandstone™ makes it a good reservoir rock.
Split Rock
This is the name given to sandstone that has visible laminations and can be easily split along the laminations. Except for the laminations, some split rock can be classified as homogeneous and usually falls in the 50 to 300 milidarcy range.
