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 held together by silica. The relatively high porosity and permeability of Berea Sandstone™ makes it a good reservoir rock.
There are 3 variations of the sandstone used for our core samples:
- "Split Rock" has visible laminations but can be classified as homogeneous. This usually offers the lower mD ratings.
- "Liver Rocks" has very little, to no visible laminations and is considered homogeneous. This is our most prevalent core rock, and runs in the 200-500mD ranges. Some of these samples have readings as high as 700mD.
- "Dundee" samples are from the Massilon Formation. While having consistent porosities and densities to our Berea Sandstone™, our Ohio Sandstone samples are not considered homogeneous. Its laminations do not run parallel to each other and is very porous, therefore yielding the higher ratings of 900mD-2500mD.
We currently have core material available in ranges from 19mD thru 2500mD, with ambient porosities from 13% to 23%.
Cleveland Quarries supplies Berea Sandstone™ Cores in a wide variety or shapes and sizes; raw core blocks for customer cutting, cut core blocks, cylindrical cores (1/2" and up), and dimensioned cores (rectangular, square, and irregular shapes).
